Comprehensive circuit monitoring and corresponding indicators: each circuit is equipped with monitoring functions on fire, circuit break and short circuit, respectively
The fire alarm circuit and the indicator circuit are able to detect circuit break and offer protection against short circuit
The system always keeps close watch over battery charging and the voltage of the stand-by battery to ensure that the central control unit functions well in all circumstances to prevent any disaster
Each circuit is equipped with a testing button to ensure the normal function of each monitoring circuit
Key-controlled function switchesprevent false alarms caused by accidental touch
Digital detection of voltage error: whenever a voltage error is detected by the system, an error alarm will sound and an indicator will light on
The system is equipped with atwo-stage accumulation functionto prevent false alarms. When the detector activates for the first time, the system will automatically reset the detector. If another signal is received later, the system will then confirm that there is a fire, for fear of a false alarm
“Self-Protection” mode and “Non Self-Protection” modeare available to fire alarms
Separate control switches: separate control panels for main audio, local audio, indicators, and reporting output
There is a “Not-Located” indicator above each switch
Digital-electronic switches are used due to advantages of dust proofing and a long service life
A control panel with all necessary master indicators: the status of system alarm, power supply quality, and circuit connection are shown
The alarm buzzer sounds in a loud voice: personnel in charge will be informed immediately in case of a firm alarm
