Installation of the device
General information:
-
When choosing the installation location make sure the displays of the device are clearly visible.
-
Screw the air sampling smoke detection system either directly to the wall with its bottom casing or mount it by means of a special support (type
MT-1). This support allows to mount the device also to racks for example.
-
The air outlet of the device must not be blocked. (The distance between the air outlet and adjacent objects (e.g. wall) is to be at least 10 cm.)
-
The air sampling smoke detection system can be mounted with the air sampling pipe connector(s) pointing upwards or downwards. (If neces-
sary, turn the lid by 180
°
). If the air sampling pipe connector(s) point downwards make sure no impurities enter the air outlet which then points
upwards.
-
At switching-on the supply voltage, the device does not start running at once but only after approx. 10 seconds.
Procedure:
1. First, clearly mark the fixing points for mounting the device. If necessary, use the provided drilling jig. Fix the device using four screws (max.
∅
of 6
mm for wall mounting and max.
∅
of 4 mm for mounting by means of the device support MT-1) in order to guarantee a safe fixing and to limit vibra-
tions which occur.
2. Fix the device by means of four screws in accordance with the mounting type to the wall or the device support. Make sure the device is not fixed
under mechanical tension or the screws are not tightened too much. Otherwise the device might be damaged, or unintended secondary noise may
arise.
Note:
To balance unevenness and/or to avoid vibrations vibration dampers need to be installed.
3. Carefully break out of the housing the required cable entries (max. 5 x M20 und 2 x M25). If required, use a screwdriver.
4. Carefully equip the cable entry(entries) according to requirements with M20 or M25 glands (2x M25, 1x M20 included in the delivery) by inserting
them into the corresponding cable entry/entries.
5. Pass the connection cable(s) (max. 1.5 mm²) required to wire the device through the prepared M20 or M25 glands into the device and cut it to the
required length within the device.
6. Wire the device according to the following connection diagram.
