1. General

1.1 Introduction

This report describes the marine type approval testing of five types of analogue address-able smoke and heat detectors carried out to achieve compliance with the specification:

• IACS E10 "Test Specification for Type Approval", Rev. 4, May 2004, issued by the International Association of Classification Societies (IACS)

An assessment to verify if the detectors fulfil the relevant requirements of the IACS E10 by evaluation of the validity of the previous tests and the standards used at that time compared with the IACS E10 has previously been carried out and reported. The assess-ment was reported in Ref. /1/ of Section 1.6. The assessment report describes which sup-plementary marine tests should be carried out to achieve compliance with the IACS E10 specification. In addition to these tests, Consilium Marine AB also requested dry heat and damp heat cyclic to be included for the heat detectors class A1R. This resulted in the following test plan, where the notation is defined in Table 1:

in Ref. /1/ of Section 1.6.

The marine base type SPB-ADAPT is used for all the types of tested detectors.

Since the detector type EV-H-CS is exactly the same detector as the EV-H-A1R, except for the detector class and suffix, the type testing of the EV-H-A1R also covers the type testing of the EV-H-CS for some of the tests as described in the test programme in Table 1.

The functional testing of the test objects was carried out by measuring the Response Time (RT) of the heat detectors and the Response Threshold Value (RTV) of the smoke detectors before and after the environmental conditioning as described in Section 1.3.2.

Also, a simple functional test was carried out before, during if specified, and after the environmental testing as described in Section 1.3.1.

The results of the tests in standard environment and the environmental tests are given in Chapters 2 and 3.

A summary of all the test results is given in Chapter 4.

All measuring equipment used during the tests has been calibrated according to the re-quirements given by the accreditation.

The test results relate to the tested objects only.

1.2 Test set-up

Test set-up connection diagram is enclosed in Annex 2.

Consilium Marine AB delivered three test set-ups, control unit/power supplies, and 4 - 7 samples of each detector type for the marine type testing.

Each of the three test set-ups consists of an analogue addressable detection circuit, where it is possible to connect different numbers of detectors and different types of detectors to the analogue loop.

The first control unit/power supply is used for the measurements of all response times and response threshold values in the test tunnel. This control unit has 1 or 2 detectors connected to the loop at a time and a relay output for signalling alarm condition from the individual detectors to the test tunnel data acquisition system.

For the detector type EV-PH, there are two separate relay outputs, one for the smoke de-tector part and one for the heat detector part.

The second control unit/power supply is used for the salt mist testing. This unit has one of each type of the detectors type EV-H-A1R, EV-P, EV-DP and EV-PH connected to the loop during the test. This means that 4 marine bases are connected to the analogue loop with 10 cm between the bases and 6 m between the detectors and the control unit.

The third control unit/power supply is used for all other environmental tests. This unit can have one of each type of all 5 detectors connected to the loop during the testing, in-cluding the detector type EV-H-CS. It is possible to remove the detector type EV-H-CS from the loop during certain tests without removing the base from the loop. 5 marine bases are connected to the analogue loop with 3 m between the detectors and 20 m be-tween the detectors and the control unit.

The detectors are mounted in IP55 marine bases type SPB-ADAPT during the type test-ing.

The cable used in the test set-up is a typical unshielded installation cable.

The revision numbers of the different types of tested detectors at the start of the marine type testing and during the complete marine type testing period are given in Table 2. The revision number is for the complete detector.

1.3 Functional test procedure

1.3.1 Simple functional testing

A simple functional test of all the tested detectors was performed.

The simple functional test was carried out before, during (if specified) and after each of the environmental tests.

The simple functional test included the following activities:

Smoke detectors : Smoke from a match or test gas was blown into the detector (alarm condition and reset).

Heat detectors : Heat from a hair dryer was blown into the detector (alarm con-dition and reset).

The LED on the detector and the readings on the control unit to which the detector was connected were observed.

1.3.2 Measurements of response time for heat detectors and response threshold value for smoke detectors

The sensitivity of the test objects was found by measuring the Response Time (RT) of the heat detectors and the Response Threshold Value (RTV) of the smoke detectors. These measurements were performed before and after the environmental conditioning.

The response time for each type of heat detector was measured after the conditioning at rate of rise of air temperatures of 3 K min-1 and 20 K min-1 in the orientation which gave the maximum response time in the directional dependence test according to EN54-5, as specified in the LPCB reports from previous type testing (see the report ref. /1/ in Sec-tion 1.6), and compared with the response time measured for the same detector before the environmental test.

The response threshold value of each type of smoke detector was measured after the conditioning in the least sensitive orientation of the detector as measured in the direc-tional dependence test according to EN54-7, as specified in the LPCB reports from pre-vious type testing (see the report ref. /1/ in Section 1.6), and compared with the response time measured for the same detector before the environmental test.

Directional dependence - least sensitive orientation: Detector Heat

[Maximum response time] Smoke [mmax]

EV-H-A1R 180º - EV-H-CS 180º - EV-P - 315º EV-DP - 135º EV-PH 315º 270º

For the heat detectors, the least sensitive orientation is the orientation which resulted in the maximum response time in the previous directional dependence testing.

For optical smoke detectors, the least sensitive orientation is the orientation which re-sulted in the maximum response threshold value which is designated mmax.

For all the tested detectors, the 0° orientation was defined as the direction with the align-ment notch pointing downstream with regard to the airflow in the test tunnel. The test object was rotated clockwise when viewed from below with the detector mounted at the ceiling.

The results of the functional tests are given in Chapters 2 and 3.

1.4 General criteria for passing the tests

The following general criteria have been used as a basis for passing the tests in this re-port:

Functioning

The testing in standard environment and the environmental testing shall not cause mal-functioning of the test object.

The test object shall function correctly when subjected to the simple functional testing as specified in Section 1.3.1 above.

The RT and RTV values measured before and after the environmental testing as speci-fied in Section 1.3.2 above are compared.

For the heat detectors, the response time measured shall be above the lower limit of re-sponse time and below the maximum deviation in response times measured before and after the environmental testing according to EN54-5.

For the optical smoke detectors, the ratio between the maximum and minimum response threshold values (mmax and mmin) measured before and after the environmental testing ac-cording to EN54-7 shall be equal to or below 1.6.

Visual inspection

The testing shall not cause damage or degradation likely to jeopardise the correct func-tioning of the test object.

1.5 Modifications of test objects during testing

The type approval testing revealed that modifications of some of the test objects were necessary to pass certain tests. The modifications are described in the summary in Annex 4 and mentioned in the relevant sections of Chapters 2 and 3.

2.2 High voltage

Test objects

EV-H-A1R EV-P EV-DP EV-PH.

Specification

IACS E10 Req. 1993/Rec.4, 2004, Test no. 10.

Procedure

One of each type of detector in its marine base is tested as specified in the standard, ex-cept for the EV-H-CS detector, which was not included in this test. With respect to this test it is similar to EV-H-A1R, as described in Section 1.1, Introduction

For each type of detector, a test voltage of 574 VAC, 50 Hz is applied for one minute be-tween shorted supply terminals (loop or detection line) and an aluminium earth plate to which the detector is mounted.

During the conditioning, it is monitored that no flashover, breakdown, etc. occurs.

A simple functional test is performed after the conditioning.

The insulation resistance is measured after the high voltage test and compared with the initial measurements of the insulation resistance as described in Section 2.1.

The response times for each type of heat detector are measured after the conditioning and compared with the results achieved before the conditioning.

The response threshold value for each smoke detector is measured after the conditioning and compared with the results achieved before the conditioning.

Results

No flashover or breakdown was observed during the conditioning, and the simple func-tional test was OK after the conditioning.

The insulation resistance measured was within the required limits. Please see results in Section 2.1.

The response time of each type of heat detector was measured and compared with the measurement before the conditioning as follows:

3. Environmental tests This chapter describes the environmental tests. The tests are described with reference to test objects, specification and procedure.

3.1 Dry heat

Test objects

EV-H-A1R EV-H-CS EV-P EV-DP EV-PH.

Specification


Procedure

IEC 60068-2-2 (1974), Test Bd: Dry heat for heat-dissipating object with gradual change of temperature, Amendment 1 (1993), Amendment 2 (1994).

Temperature : +70°C Duration : 2 hours Humidity : Below 50 %RH

One of each type of detector in its marine base is tested as specified in the standard.

The test objects are energised and monitored in quiescent condition during the condition-ing, except for the EV-H-A1R and EV-PH which are in heat alarm condition at this tem-perature, and it is monitored that they cannot be reset.

During the last hour of the conditioning, a simple functional test is performed. After re-covery, the simple functional test is repeated in standard environment.



Since the same EV-H-A1R detector and EV-PH detector was used for the three tests: dry heat, cold and damp heat, cyclic, carried out in this sequence, the intermediate functional test for these detectors was deleted. Only before and after the end of this sequence of tests, a functional test was carried out. Therefore, the measured response threshold


EbC/jh

levels/response times for these detectors are included in the test results of the dry heat test.

Results

Except as mentioned below, no malfunction was observed during the conditioning and the simple functional test was OK during the last hour of the conditioning period at the high temperature as well as after recovery.

At +70°C the EV-H-A1R and EV-PH were correctly in heat alarm condition and could not be reset.

The detectors all passed the dry heat test, but with the comments given below.

Comments

The dry heat test revealed that the built-in LED of the detector type EV-H-A1R did not light up when in alarm condition. Otherwise, it functioned correctly in all other aspects, and the alarm signal was correctly received by the CS4000 control panel.

A subsequent failure analysis made by Nittan showed that the fault was caused by a bad soldering. The detector was repaired and sent back to DELTA for inspection and found to be functioning correctly.

Please see information regarding the fault in Chapter 4.

3.2 Damp heat, cyclic

Test objects

EV-H-A1R EV-H-CS EV-P EV-DP EV-PH.

Specification

IACS E10: Req. 1993/Rec.4, 2004, 1997, Test no. 6.


EbC/jh

Procedure

IEC 60068-2-30 (1980), Test Db: Damp heat cyclic (12 + 12 hours' cycle), Variant 1, Amendment 1 (1985).

Lower temperature : 25°C Humidity at lower temperature : >95 %RH

Upper temperature : 55°C Humidity at upper temperature : 93 %RH Number of cycles : 2

One of each type of detector in its marine base is tested as specified in the standard.

The test objects are energised and in quiescent condition during the first cycle. A simple functional test is performed during the first 2 hours of the 55°C phase.

During the rise of temperature to the high temperature, condensation on the test objects is ensured.

During the second cycle, the test objects are deenergised. However, once within the last 2 hours of the second 55°C phase, the test objects are energised temporarily for a simple functional test to be performed.

After recovery, a simple functional test is carried out.




Since the same EV-H-A1R detector and EV-PH detector were used for the three tests: dry heat, cold and damp heat, cyclic, carried out in a sequence, the intermediate func-tional test for these detectors was deleted. Only before and after the end of this sequence of tests, a functional test was carried out. Therefore, the measured response threshold levels /response times for these detectors is included in the test results of the dry heat test in Section 3.1.

Similarly, the same EV-P detector and EV-DP detector were used for the two tests: cold and damp heat, cyclic, carried out in a sequence, the intermediate functional test was de-leted. Only before and after the end of these tests, a functional test was carried out. Therefore, the measured response threshold levels/response times for these detectors is included in the test results of the cold test in Section 3.4.


EbC/jh

Results

Except as mentioned below, no malfunction was observed during the conditioning, and the simple function of the test objects was OK during the first and second cycle at 55°C, 93 %RH and after recovery. No corrosion attack was observed after the conditioning.


The response time of each type of heat detector was measured and compared with the measurement before the conditioning.

The results for the detectors type EV-H-A1R and EV-PH are included in the test results of the dry heat test in Section 3.1.

The response time for the heat detector type EV-H-CS was measured and compared with the measurement before the conditioning as follows:

EV-H-CS Orientation of test object: 180°

after env. test





The response threshold value of each type of smoke detectors was measured and com-pared with the measurement before the conditioning.

The results for the detector type EV-PH are included in the test results of the dry heat test in Section 3.1.

The results for the detectors type EV-P and EV-DP are included in the test results of the cold test in Section 3.4.



The detectors all passed the damp heat, cyclic test, but with the comments given below.


EbC/jh

Comments

The damp heat test revealed that the built-in LED of the detector type EV-H-A1R did not light up when in alarm condition. Otherwise, it functioned correctly in all other as-pects, and the alarm signal was correctly received by the CS4000 control panel.

A subsequent failure analysis made by Nittan showed that the fault was caused by a bad soldering. The detector was repaired and sent back to DELTA for inspection and found to be functioning correctly.

Also, the damp heat test revealed that when switching on at the second simple functional test during the exposure, the EV-PH gave the indication SENSOR FAULT (129) on the control panel.

The fault could not be reset before heat and smoke alarms had been subsequently pro-voked.

A new detector type EV-PH from an improved controlled production was tested at DELTA in a second damp heat, cyclic test, including initial and final response parame-ters, insulation resistance and simple function check. The new detector passed the damp heat, cyclic test without comments.

Please see information regarding the fault in Chapter 4.

3.3 Vibration

Test objects


Specification


Procedure

IEC 60068-2-6 (1985), Test Fc: Vibration (sinusoidal).

Response investigation (test objects switched off) followed by endurance by frequency dwelling (switched on) is carried out in each of three axes using the following parame-ters:


EbC/jh

Frequency range : 2 - 100 Hz Frequency/amplitude : 2 - 25 Hz : ±1.6 mm 25-100 Hz : ±4 g Sweep rate : Max. 1 octave/min. Number of axes : 3 mutually perpendicular

One of each type of detector in its marine base is tested as specified in the standard, ex-cept for the EV-H-CS detector, which was not included in this test. With respect to this test, it is similar to EV-H-A1R, as described in Section 1.1, Introduction

During the response investigation, resonance frequencies are determined by means of stroboscopic light with slow-motion facility and accelerometer measurements of the am-plification factors (Q). Resonance frequencies with Q≥ 2 are recorded.

Endurance by frequency dwelling is carried out for 90 minutes at each resonance fre-quency with a Q≥ 2, or 90 minutes at 30 Hz if no such resonances are found.

A simple functional test and visual inspection is performed after the conditioning.

Results

No resonance frequencies with an amplification factor above 2 were recorded for any of the tested detectors.

No damage or malfunction was observed during or after the exposures and the simple function test was OK after the test.

The test objects are deenergised during the conditioning. However, during the last hour of the conditioning at the low temperature, the test objects are energised and a simple functional test is performed. After recovery, a simple functional test is carried out.




Since the same EV-H-A1R detector and EV-PH detector were used for the three tests: dry heat, cold and damp heat, cyclic, carried out in a sequence, the intermediate func-tional test for these detectors was deleted. Only before and after the end of this sequence of tests, a functional test was carried out. Therefore, the measured response threshold

Similarly, the same EV-P detector and EV-DP detector were used for the two tests: cold and damp heat, cyclic, carried out in a sequence, the intermediate functional test was de-leted. Only before and after the end of these tests, a functional test was carried out. Therefore, the measured response threshold levels/response times for these detectors is included in the test results of the cold test in Section 3.4.

Results

No malfunction was observed when energising the test objects, and the simple functional test was OK during the last hour of the conditioning period at the low temperature and after recovery. (It is noted that the same detector type EV-H-A1R as tested during the previous dry heat test now functioned correctly with its LED lighting up in alarm condi-tion, both during and after this exposure.)


The response time of each type of heat detector was measured and compared with the measurement before the conditioning.

The results for the detectors type EV-H-A1R and EV-PH are included in the test results of the dry heat test in Section 3.1.

The response threshold value of each type of smoke detectors was measured and com-pared with the measurement before the conditioning.

The results for the detector type EV-PH is included in the test results of the dry heat test in Section 3.1.

0.30 - 30 MHz : 52 - 34 dBμV/m

30 - 2000 MHz : 54 dBμV/m, except for 156 - 165 MHz : 24 dBμV/m Photo of test set-up : See annex 3


The electric field is measured with antennas at a distance of 3 m.

The test objects are energised and in quiescent condition during the measurement.

Results

The measured emission from 0.15 to 2000 MHz was below the limits for all the test ob-jects.

The detectors all passed the salt mist test without comments.

4. Summary The five smoke and heat detector types from Consilium Marine AB as listed on Page 2 have been subjected to type approval testing based on IACS E10 test procedures. The tests carried out and the results are listed in the table below.

According to the assessment report A530269 mentioned in Ref. /1/ in Section 1.6, the requirements of the IACS E10 are covered by including the selected E10 tests listed be-low, since the E10 tests not included here are covered by previous testing as described in Ref. /1/ in Section 1.6.

All functional testing before and after the environmental tests was carried out according to EN54-5 for heat detectors and EN54-7 for smoke detectors.

The test results can be summarised as follows. (Detailed information is given in Chapters 2 and 3)

Test Specification Results Visual inspection IACS E10, test no. 1 OK Performance test IACS E10, test no. 2,

EN54-5, EN54-7 OK

Insulation resistance IACS E10, test no. 9 OK High voltage IACS E10, test no. 10 OK Dry heat, +70ºC IACS E10, test no. 5 OK, See note 1) Damp heat, cyclic, 55ºC IACS E10, test no. 6 OK, See note 1) and 2) Vibration IACS E10, test no. 7 OK Cold, -25ºC IACS E10, test no. 11 OK Salt mist IACS E10, test no. 12 OK Radiated emission IACS E10, test no. 19

(bridge and deck zone) OK

Note 1:The dry heat test and the damp heat cyclic tests revealed that the built-in LED of the detector type EV-H-A1R did not light up when in alarm condition. Otherwise, it functioned correctly in all other aspects, and the alarm signal was correctly received by the CS4000 control panel. A subsequent failure analysis made by Nittan showed that the fault was caused by a bad soldering. The detector was repaired and sent back to DELTA for inspection and found to be functioning correctly. For more details please see the Nittan, UK failure analysis report as listed in Annex 1. Note 2:The first damp heat test revealed that when switching on at the second simple functional test during the exposure, the EV-PH gave the indication SENSOR FAULT (129) on the control panel. The fault could not be reset before heat and smoke alarms had been subsequently provoked. Application of heat produced both heat and smoke alarm indications. Application of smoke correctly produced only smoke alarm. A subsequent failure analysis made by Nittan showed that the fault was caused by contamination of the circuit board during the soldering process as well as errors in the conformal coating applied at the manufacturing. A new detector type EV-PH from an improved controlled production was tested at DELTA in a second damp heat, cyclic test, including initial and final response parameters, insulation resistance and simple function check. The new detector passed the damp heat, cyclic test without comments. For more details please see the Nittan, UK failure analysis report as listed in Annex 1.
