whether the detector alarms normally and control panel displays its registered address.
 Reset：After testing, reset the detector through control panel.
Fault Finding
Detector Fault on
Control Panel
Check wiring of Common base , no water no short-circuit and open circuit.
Chenk the connection between detector and common base.
Nuisance alarm The detector alarm frequently but there is no Fire and other unusual, then check whether
the chamber in the detector is too dirty and needs to be cleaned
Otherwise, the circuit may be broken.
Address Fault Address is set incorrectly,Reset by VI-6537 Digital Programmer.
