Features
Each circuit is equipped with LED indicators for fire, circuit break and short circuit,respectively.
Whenever a voltage error is detected by the system, an error alarm will sound and〝charger fault〞an indicator will illuminated.
At the first stage, when the detector sends the signal for the first time, the control panel will automatically reset the signal and enter the second stage for standby after 8 seconds.
At the second stage, if there is another signal sent by the detectors within 9-40 seconds, the control panel will triggered the fire alarm, else reset the alarm signal. This will prevent the control panel from sending false alarms.
alarm, power supply and circuit connection fault.
