Functional principle
Scatter light, adaption of the alarm threshold, no alarm saving (self-reset-
ting as soon as there is no longer any smoke in the measuring chamber)
Insect grid
prevents insects getting into the measuring chamber.

with test magnet near the magnetic sensor (GEZE logo)
with test aerosol
The detector test using a test magnet tests the electrical compo-
nents. The detector test which forms part of the regular testing of
the hold-open system must be carried out using a test aerosol
(see chap. 6.2.2).
