General Introduction
All base board adopt a modular design. Wiring is stable. External appearance is simple and elegant. With two phase accumulation function to reduce false alarm, operator can know the situation instanly and maintenance is also easy.
Description of Functions
– Accumulation function : Fire alarm will be activated only if signal is receives for the second time after 8-10 second gap. If there is no signal is received for the second time after the time period, memory would be automaticcally cleared after 60 seconds of the first signal.
– Stand by power supply protection device. In case of power failure, when standby voltage reaches below DC 18V, discharge will be stopped automatically to extend battery life.
– External wires are connected to the terminal wiring board separated from circuit boards. In case of maintenance, the circuit board can be independently and easily repleaced without removing external lines.
Electrical Features
– Over voltage : Red LED on, indicating system voltage is over high.
– Normal voltage : Green LED on, indicating system voltage is normal.
– Under voltage : Yellow LED on, indicating system voltage is over low.
List of Panel LED indication
– AC lamp: Green LED on, indicating AC power supply is in normal condition
– Reserve Power Lamp: Yellow LED on, indicating standby power in use.
– Manual call point signal/artificial message dispatch lamp : Red LED on, indicates signal from manual call point, fire alarm is also activated
