Description
VG-6627 Digital smoke detector can compensate the variation of environmental parameters and judge fire alarms
through algorithm fixed inside the excellent MCU, and send current operating state, smoke concentration,
environment parameter etc.to control panel via digital signals transmission. With the pleasing appearance, it is easy to
install and maintain. The detector is suitable for hotels, restaurants, computer rooms, banks, malls, warehouses,
libraries, museums, offices and places with heavy moistures among the air. Besides, it is also applicable for places
where black smokes occurred when there is fire.

Testing
Warning：Power is switched off before all devices are installed completely.
The detector must be tested after installation or regular maintenance.
Registration: The fire alarm control panel will registers the detector on line to check if the address of the
detectors mounted is the same address as that registered in the control panel.
Fire condition: After registration, make detector under fire conditions by using Smoke generator to test
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 VG-6537 Digital Programmer.
