Installing the Unit
Notice!
When selecting the installation location, it must be ensured that the unit displays are easily
visible.
Remember when planning that the unit fans generate a noise level of approx. 45 dB(A).
The installation location may not be in any door opening area.
The air outlet on the unit must not be obstructed. There must be a free area of 10 cm in front
of the air outlet.
The aspiration smoke detector can be installed with the aspiration device pointing upwards or
downwards. Rotate the cover through 180° in the required direction.

Aspiration from below
If the air-return pipe is directed upwards, it must be guaranteed that no foreign bodies or
dripping water can penetrate the air return. You should therefore use a short, downward
angled pipe.
Mounting type MT-1
The Aspiration smoke detector is either bolted directly to the wall provided for
installation using the rear panel or installed by means of unit mounting type MT-1, e.g.
onto frames.
First, clearly mark the fixing points on the installation position provided on the
equipment. Use the supplied drilling jig as an aid. To guarantee a safe and low-vibration
hold, the unit must be secured with four screws.
Using four screws appropriate for the installation method, attach the unit securely to the
surface or to the unit mounting. Ensure that the unit is not fixed under mechanical stress
and that the screws are not tightened too tightly, otherwise damage or undesirable
resonance noises could occur. To equalize unevenness and/or prevent vibrations,
vibration absorbers (subject to separate order) must be used.
Using a screwdriver, carefully punch out the required cable entry points of the housing
(max. 5 x M20 and 2 x M25).
Fit the cable entry point(s) as required with M20 or M25 connections by pushing them
into the cable entries. 2 x M25 and 1 x M20 are supplied in the pack.
Punch out the cable entries using a sharp object.
Caution: Do not cut the cable entries with a knife!
Route the connection cable(s) (max. 2.5 mm2) through the prepared M20 or M25
connections and into the unit. Now cut these to the required length inside the unit.
