How to Operate
5-1. Preparation for start-up
Before connecting a power supply, read and understand the following precautions. Ignoring these
precautions may cause an electric shock or damage the detector.

Check that the detector is installed properly.

Connect the detector to a grounding circuit.

Check that the external wiring is done properly.
5-2. How to start the detector
Before supplying power to the detector, check that the preparations described in "5-1. Preparation for
start-up" are completed. Turn on the indicator/alarm unit power and check that it functions normally with
reference to the operating manual of the indicator/alarm unit.
5-3. How to detect
Turn on the power switch of the indicator/alarm unit. Gas detection starts after the initial clear.
5-4. How to exit
Turn off the power switch of the indicator/alarm unit.
CAUTION

When the detector is installed newly or the sensor is replaced with new one, 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. Only as a guide, perform a warm-up of around one hour after
switching it on.

After the warm-up is completed, perform a calibration.
WARNING

When the detector is turned off, an alarm may be triggered on the upper (central) system.

Before turning off the detector, INHIBIT (point skip) on the upper (central) system must be
activated.
Also, check the operation of the devices connected to this gas leak detection/alarm system to
see if power can be turned off.
