7-2 Performing alarm tests
A signal is emitted that simulates a gas concentration, enabling checks of the alarm lamps and the status
of signal transmissions to external devices.
WARNING

Before starting an alarm test, notify the related departments so that measures can be taken to
ensure that problems do not arise due to external output signals or alarm contacts.

When the alarm test is complete, hold down the TEST/SET key to return to the detection mode. The
product will not detect gases while in the adjustment/setting state. If left in alarm test mode, the
product will return to detection mode after 10 hours. Note that this is dangerous because no
monitoring occurs during this time.

seconds.
