Device errors
If a malfunction has occurred which limits the functional scope of the heat detector, the
heat detector signals a device error.
The heat detector issues an acoustic signal every 32 seconds; the signal LED (4) does
not
flash.
Check the functionality of the heat detector or change the heat detector.
Mute mode
If an alarm has been triggered on one or more heat detectors, Mute mode can be acti-
vated by pressing the Test button (5).
Die Signal-LED (4) flashes every 8 seconds for a period of 10 minutes.
Mute mode is activated for 10 minutes. After 10 minutes, the alarm is either extended
or ended automatically, depending on the temperature. In the case it is extended, the
device switches to Alarm mode.
Test mode
You should test the heat detector on a weekly basis by pressing the Test button (5). The
heat detector issues a loud acoustic alarm to confirm its functionality.
