Timer and Special Timer (T and S)
In order to lower the false alarm rate, the Alarm Threshold of analogue de-
tectors must be INCREASED during Day mode (to allow for cigarette
smoke, heaters, etc.).
The Timer can be set to activate/deactivate (ON/OFF) the Increased
Alarm Threshold value.
The Special Timer is especially useful in work places with split shifts (fac-
tories, offices, etc.).
Both Timers have exactly the same programming and operating modes.

Threshold must be restored.
