FIXED TEMPERATURE HEAT DETECTOR WITH ADDRESS MODULE ÏÎÆÀÐÎÈÇÂÅÑÒÈÒÅË ÒÅÐÌÈ×ÅÍ ÌÀÊÑÈÌÀËEÍ Ñ ÀÄÐÅÑÅÍ ÌÎÄÓË 6110L 1. INTRODUCTION The fixed temperature heat detector is designed to provide early warning of a fire condition reacting upon ambient temperature reaching a fixed temperature threshold. 2. STRUCTURE AND FUNCTION The detector consists of two main parts: a base and a detector head. The latter comprises a circuit board and a chamber with heat sensitive element. The contact plates are fixed to the base. The detector head is fixed on the base by the means of bayonet joints. When locating the detector head on the base, make sure the bench mark stands about 20 mm before the respective bench mark on the base; then rotate clockwise to fix. The bench marks should fully coincide when fixed. A flat point screw is provided on the detector head to prevent unauthorized removal. A 2 mm tip screwdriver is required for locking and unlocking. The principle of function of the detector is based on the ohmic resistance alteration in the thermistor as a result of the ambient temperature change. Upon activation the detector illuminates two red LEDs, situated on the detector head (360° visibility). The LEDs can be reset and extinguished by momentarily removing the power source. Detectors type and sensitivity are marked. On fig.2 is shown DIP switch for the addresses and the address number label. The DIP switch is protected by a transparent cover. Address assign- ment is made through the DIP switch, according Fire Control Panel FS6000 Instruction Manual, Appendix 9. Fire detectors addressing is made via spe- cial communication protocol. 3. PREPARING THE DETECTOR FOR OPERATION 3.1. Connection diagram Connection diagram of a fire detector base to two - wire fire alarm line, using shielded wire, is shown on fig. 3. Shielded wire is strongly recom- mended for reducing electromagnetic interferences. 3.2. Ìounting Separate the base from the detector head by turning the detector head in an anti-clockwise direction. Feed the connection cable through the cable entry in the center of the base. Fix the base on the ceiling using appropriate fixings. Complete the wiring as shown on fig. 3. Fix the address label on its appropriate place. Pull the protection cover and assign the necessary address through the DIP switch. After completion replace the cover and press until a click sound is heard. Note: DIP switch should not be set to middle (null) position, because it would cause an incorrect reception of a fire detector address by the fire control panel. Replace the detector head on the base by offering the detector head to the base ensuring bench marks are no more than 20 mm apart. Rotate the detector head in a clockwise direction to complete location. Lock the detector head to the base by screwing the flat point screw, using a 2 mm tip screwdriver, ensure not to over tighten. 3.3. Testing Test is made when the fire detector is connected to FS6000 Fire control panel and according the provided test procedures. Place a permanent magnet on the detector heads surface at the point marked test periphery. The twin LEDs will illuminate. After removing the magnet the LEDs should re- main lit until reset by momentary interruption of the power supply. In addi- tion a simulation test of real fire conditions should be completed by a labo- ratory heat probe. 4. WARRANTY The manufacturer guarantees compliance with EN 54, Part 5. The warrant period is 36 months from the date of purchase, providing that require- ments stated in the service schedule have been observed. 1.ÏÐÅÄÍÀÇÍÀ×ÅÍÈÅ Ïîæàðîèçâåñòèòåë òåðìè÷åí, ìàêñèìàëåí å ïðåäíàçíà÷åí çà îòêðèâàíå íà ïîæàðè â ðàííèÿ ñòàäèé, êàòî ðåàãèðà íàä îïðåäåëåíà òåìïåðàòóðà. 2.
