General Introduction
All base boards 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 instantly and maintenance is also easy.
Description Of Functions
1. Accumulation function: Fire alarm will be activated only if signal is received for the second time after 8-10 seconds gap. If there is no signal is received for the second time after the time period, memory would be automatically cleared after 60 seconds of the first signal.
2. Standby 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.
3. 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 replaced without removing external lines.
