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

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 gas calibration.
