WARNING
•
Before starting the alarm test (transmission test), provide a notification to the related sections so
that they can prepare for false abnormalities (external output signals and alarm contact). After
the test is completed, never fail to press MENU/ESC key to return to the detection mode. (If the
detector remains in the alarm test mode, it automatically returns to the detection mode in ten
hours.)
•
In the alarm test mode, the gas concentration equal to the reading is output even in the
maintenance mode depending on the setting. Take actions, if necessary, so that the signal
receiver side can prepare to avoid false alarms.
