Setting the Fan Voltage (SL Variant)
For FAS-420-xx systems, the standard fan voltage setting is 6.9 V.
CAUTION!
For SL variants, the jumper BR4 on the motherboard always needs to be removed (see
Figure 4, Page 5).
Close or open the jumpers BR1 and BR2 only when the device is switched off.
Re-initialize the airflow if you have switched the fan voltage.
The fan voltage on the fan activation circuit board on SL devices is set using jumpers BR1 and
BR2. The default setting is marked in bold.

Number of Detector Modules
See Figure 4, Page 5.
The number of populated detector modules is factory set depending on the model variant
(jumper BR1 on the motherboard).

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 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 aspiration device pointing up or
down (to do this, rotate the housing cover through 180°). If the aspiration device points
down, make sure no impurities enter the air return pipe, which will be pointing up.
The aspirating smoke detector is either screwed directly to the installation wall by the
rear panel or installed using unit mounting type MT-1, e.g. on frames (see Figure 5,
Page 5: 1 = horizontal installation, 2 = vertical installation).
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 firm, low-vibration hold,
the unit must be secured with four screws (max. 6 mm Ø for wall mounting, max. 4 mm Ø
for MT-1 unit mounting).
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 balance out unevenness and/or prevent vibrations, vibration absorbers (subject to
separate order) must be used.
Using a screwdriver, carefully punch out the required cable entries on the housing (max.
5 x M20 and 2 x M25).
Fit the cable entry/entries as required with M20 or M25 connections (2 x M25 and 1 x
M20 included in the delivery) by pushing them into the cable entry/entries.
Route the connection cable(s) (max. 2.5 mm
connections and into the unit. Cut them to the required length inside the unit.
