Description

Characteristics: - 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 monitor circuit. - Key-controlled function switches prevent 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 a two-stage accumulation function to prevent false alarms. When the detector activates for the first time, the system will automatically reset the detector, 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" mode are available to fire alarms. - Separate control switches; separate control panels for main audio, local audio, indicator, 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.
