Observer 180 plus
Theory of Operation
This observer responds to thermal movement initiated by persons, animals or objects and, when
detecting, turns on consumers such as lights.
The unit remains activated as long as movements are detected. Otherwise, the observer switches off
after a preset delay time has elapsed.
A visual signal indicates the responding of the unit.
With the aid of an adjustable twilight switch, the switching function is activated from a desired
brightness value only or can be set to day-time/night-time operation.
The working range of the unit can be individually adapted by adjusting the sensitivity.
Via a mechanical flush-mounted push-button (normally closed contact), the mode can be changed:
Observer mode.
Light ON for 2 hours.
Light OFF for 2 hours.
Test mode.
