INTELLIGENT INTERFACE MODULE TO COMPUTER COMMUNICATION FAULTS

Symptom Corrective Action

No communicationbetween the IIM and thecomputer when using adirect IIM to computerconnection(Local IIM connection)

Ensure that the computer to IIM cable is plugged in to the port marked "PC" on the IIM.

Check the configuration of the OCS under the Setup/System Computer/Configuration menus. The serialport must be set to the same COM port as the communications cable is plugged in to. Connection typemust be set to "Local IIM".

Ensure that the IIM is powered and operating. Depress the hard reset on the IIM. It should momentarilyengage the trouble relay and extinguish all LEDs. The orange (lower) LED will come back on for about 1min while the IIM resets. If no action occurs, the IIM may be defective or not receiving power

Check the DB9 to RJ12 connector by separating the DB9 section from the plastic housing. The wireconfiguration must be as follows: White - Pin 2 Blue - Pin 3 Black - Pin 4 Yellow - Pin 5 Red - Pin 6 Green - Pin 8

No communicationbetween the IIM and thecomputer when using amodem and phone linesto connect to the IIM(Remote IIM Connection)

Check for proper operation of the IIM using a local IIM connection. If this fails, refer to local IIM troubleshootingsection above. If the local IIM connection functions correctly, check that the correct phone number is beingused and that the phone line is properly connected and operating.

Check the configuration of the OCS under the Setup/System Computer/Configuration menus. The serialport must be set to same COM port as the communications cable is plugged into. Connection type mustbe " Remote IIM".

Check that the characters "ATSO=1" appear in the initialisation string box of the configuration screen. Fora very few modems this string may require modification. Consult supplier if problems persist in this area.

If the previous three steps do not resolve the problem, the IIM may be defective.

GENERAL SYSTEM FAULTS

Symptom Corrective Action

Low Suction Pressure

If the system is new, ensure that the actual piping system corresponds with the layout as calculatedby the "SNIFF" design software. Items such as pipe diameters, elbows, sampling hole diameterand junction configurations should be checked.Check for proper operation of the fan module.

Check the screens located in the union, inside the detector head chamber and Elutriator.Clean if required.

Check for broken pipes, loose joints, leaky junction boxes, or missing pipe caps.Check for blockages within the pipes. The blockage can be located by checking the suctionpressure at points closest to the detector head(s) and working outward. The suction pressure willdrop downstream from the blockage.

High Suction Pressure

If the system is new, ensure that the actual piping system corresponds with the layout as calculatedby the "SNIFF" design software. Items such as pipe lengths, pipe diameters, elbows, samplinghole diameters and junction configurations should be checked.Check for blockages within the pipes and blockage of sampling ports. Pipe blockage can belocated by checking the suction pressures on the points closest to the detector head(s) and workingoutward. The suction pressures will be higher upstream of the blockage.

Long Transport Times Perform checks as outlined for low suction pressure.

Low Sensitivity to SmokePerform the sensitivity test by selecting the "sensitivity test" option from the OCS graphic displaysoptions menu. OCS will either PASS or FAIL.

Perform checks as outlined for low suction pressure.

Detector configuration is not savedafter Detector is powered down Ensure that the battery backup memory jumper is installed. (See Paragraph 4-2.10.1)

DISPLAY MODULE OR OCS GRAPHIC DISPLAY MESSAGE INDICATION CORRECTIVE ACTION

Detector Trouble Detector Head Trouble Check connections at the termination board.

Clean the detector head.

If these two steps do not resolve the problem, return the detector to thesupplier.

Display Module (if installed) COMM TR on Display Module Sounder was on even though the Display Module is not configured for sound. Date displayed was 00 JAN 2000 and time was 00:00. This does not change over time. No other troubles are shown on the Display Module STATUS menu.

OCS can communicate with the terminationboard Troubles shown: Detector, Airflow and Display Time and Date are correct on the top of the Detector graphic. Airflow is -50, but the fan is operating.

Detector Head Trouble Insure that the cable from the detector head to the termination board iscorrectly installed.

If the cable is correctly installed and the symptoms persist, return thedetector head to the supplier.

Fan is not operating.

Display Module has power but is displaying COMM trouble.

Unable to communicate to the Detector via OCS, shows "device not found"

Termination Board PowerSupply Failure

Verify the DC input voltage to the termination board is within the specifiedrange of 18 to 30 Vdc at terminals 1 and 2 on TB1. Resolve probelm withsource if necessary.

Check the termination board fuse F2 and replace if necessary. It is locatedon the lower right corner of the board. Replace with Littlefuse 1541AT.

If these two steps do not solve the problem, then the converter on thetermination board is not functioning. Return the termination board to thesupplier.

Full-Scale deflection for no apparent reason No specific event is loggedfor this fault

Check that no ambient light is penetrating the pipe and entering thedetection chamber. This can happen in brightly lit areas, especially whenwhite PVC is used as the sampling pipe.

Disconnect the sampling pipe and connect an absolute filter to theDetector. If the deflection goes to zero, there is particulate in the sampledarea. If not proceed.

Clean the detector head.

If these three steps do not resolve the problem, return the unit to thesupplier.

Airflow Trouble Low or High Airflow Level Check the real-time airflow level (see Chapter 4). Ensure that the airflowthresholds are set according to the manual.

Check for proper operation of the Fan Module.

Check for blockages or breaks in the sampling pipe network.

Check for rapid temperature fluctuations in the protected area. If found,widen the airflow thresholds.

Ensure that inlet cam is in the locked position.

Unregistered Display Module Trouble Unreg LCD Enable disply in OCS.

Power Supply Trouble PSU Trouble Measure the output voltage of the supply. It must be above 24 Vdc.

Check the power supply fault lights (only if powered by multi-zone powersupply, not the PEGAsys panel supply). Check the indicated circuit asdescribed in the four steps below.

Check the connections and continuity of the wires connected between thepower supply and the termination board.

Check that the AC voltage at the power supply input terminals is withinoperating range.

Check the battery wiring connections and continuity.

Check the batteries for low output voltage.

Check for ground fault problems throughout all associated system wiring.

Fails Sensitivity Test Detector Trouble Return Detector to supplier.

RX/TX Communication Problems PC Line Trouble Check RX/TX wiring connectors.
