Operational Description

The smoke detector has 3 operating modes:

Measuring Operation

This is shown by a blinking green light on the operation di splay

Detecting Smoke

The smoke is measured by a sender and a receiver in the IR-light area. The sender sends a

pulsed directed IR-light at a set angle to the scattered light area. This forms a defined measuring

zone below the detector, which disperses light to the smoke particles in the case of a fire. The

light goes to the receiver and the receiver sends a signal to the detector electronics. The

electronics analyses the signal and an alarm goes off if the set limit is exceeded.

Empfänger

Recognizing Manipulation

Advanced measuring instruments allow for a distinction between smoke and other types of

interference that occur within the measuring area. This way solid objects will be detected as

manipulation and the smoke detector sends an alarm signal after a set amount of time. The signal

must be reset, so that the smoke detector will work again.

Recognizing Impurities

Additional sensors are used to detect the amount of impurities on the surface of the smoke

detector. When the amount of surface impurities reaches the point that it cannot detect smoke

anymore, an alarm signal will be set off after a certain amount of time. The signal must be reset,

so that the smoke detector will work again. An early exposure of the smoke detector will also be

recognized.
