5-3. How to start the gas detector

Before supplying power (24 VDC) to the detector, check that the detector is installed properly.

Supply power (24 VDC) to the detector (turn on the detector).

After the detector completes the start-up, it enters the detection mode swiftly.
NOTE
<<Start-up Operation Procedures>> (approximately 25 seconds for system check of the detector and alarm
deactivation)
Power on -> Initial clear (approximately 25 seconds) -> Detection mode
WARNING
When the detector enters other mode from the detection mode while an alarm is activated, the alarm
is reset.
CAUTION

Do not turn off the detector during the initial clear. The detector is reading the internal memory
during the initial clear.

If the detector is installed newly or the new sensor is replaced, the sensor must be warmed up
for a specified period which is determined depending on the type of the sensor after the
detector is started.

After the warm-up is completed, perform a span adjustment.
