System Overview Installing the Device

1.

First, clearly mark the fixing points on the installation position provided on the 

equipment. To guarantee a safe and low-vibration hold, the housing base must be 

secured with four screws (

∅

max. 4 mm (0.2 inches)).

2.

Fix the housing base to the surface by means of four screws in accordance with the 

mounting type. Make sure that the housing base is not fixed under mechanical tension 

and that the screws are not tightened too much. Otherwise, the device might be 

damaged or undesirable secondary noise may arise.

3.

Using a screwdriver, carefully punch out the required cable entries from the housing 

base.

4.

Carefully fit the cable bushing(s) as required with M20 or M25 cable entries (2 x M20 and 

1 x M25 included in the delivery) by inserting them into the corresponding cable entry/

entries.

5.

Punch out the cable entries using a sharp object.

Caution: Do not cut the cable entries with a knife!

6.

Feed the ribbon cable(s) (max. 2,5 mm²) through the prepared M20 or M25 cable entries 

into the device and cut to the required length inside the device.

7.

Wire the device according to the connection information described below.

WARNING! 

The equipment may only be installed by authorized and qualified personnel!

Switch off the device before carrying out any connection work!

NOTICE! 

-

When selecting the installation location, it must be ensured that the device displays are 

easily visible.

-

Remember when planning that the device fans generate a noise level of approx.  40  

dB(A).

-

The air outlet on the unit must not be obstructed. The distance between the air outlet 

and adjacent components, e.g. a wall, must be at least 10 cm (4 inches).

-

The aspirating smoke detector can be installed with the suction device pointing up or 

down (to do this, the detection device cover must be rotated through 180°). If the 

aspiration pipe points down, make sure no impurities or dripping water enter the air 

return pipe, which will be pointing up.
