BJ-93D Combustible Gas Detector Technical Parameters

Detection method
FIGARO semiconductor gas sensor
Alarm concentration
Methane: 1% LEL ~ 25% LEL
Carbon monoxide: 50 x 10-6 ~ 300 x 10-6
Power supply
AC220V ± 15%
Power consumption

Alarm methane / carbon monoxide alarm lights, intermittent buzzer sound (alarm sound over 
70dB), delay after about 20S output contact is closed and the output drive an external 
solenoid valve action signal, fault indicator flashes.

Over-temperature alarm
the ambient temperature exceeds 70°C, carbon monoxide and methane warning lights 
warning lights flashing alternately, buzzer intermittent sound (70dB alarm sound above), 
after a delay of about 20S output contact is closed and the output drive an external 
solenoid valve action signal, fault indicator flashes.

When the fault alarm
(sensor failure) fault indicator light, buzzer continuous sound.
Output delay
20 seconds after the alarm output (can be changed according to user requirements)
