STORAGE COMPOUND
  Characteristics Of Circuit
Lighting protection circuits, avoid high voltage penetration and keep stable circuit voltage.
Termanal resistors configured on the circuit board.
Every circuit with an isolating switch.
In operation, switch in off position to avoid power failuare false report.
Short circuit indicating light at every 5L joint-postion recognizes short circuit from motion perception.


Storage Function
2-phase signal confirmation.
Help to elimantae false fo disturbance.
Auto reset the first reported fire alarm signal and re-perform scanning and detection before sending alarm message.


Main Circuit Board
External indicating lights and zone bells relay-controlled, voltage output stable.
All fuse wires with protectors and power failure indicating lights.
Stable voltage IC-control battery charge, enable extend battery time.
 
Design
External lines configured into PCB through wiring ducts to avoid short circuit caused by external line's contact with internal lines.
Easy to maintain- Int the evernt of power failure, unplug power cord to replace defected circuit.
A special designed IC-control supervisory LED, on the back of the panel, provides monitoring the machine operation. And it is constantly flashing when monitoring.
