General Introduction
The concept of module design is applied to each circuit board. Performance of the circuit is stable. Appearance is elegance.
The function unction of automatic testing makes operation and maintenance easily and effectively.

Description of Functions
1. Accumulation function : Fire warning will be activated only after circuit detection and confirmation
after certain period of time. This function can eliminate circuit interference and reporting mistakes,
as well as increase the reliability of the mainframe.
2. Automatic circuit detection : Digital-counting scanning is applied to automatic circuit detection.
This function assures that each circuit is functioning in normal condition.( Optional model)
3. Standby power supply protection device : In case of power failure and the standby battery voltage
below DC 18V, discharge will be stopped automatically to extend battery life.
4. Integration design : External wires are configured into the terminal wiring board through wiring
ducts and separated from circuit boards. In case of maintenance, the circuit board can be independently and promptly removed without removing the external lines.
