Installation position and space requirements
2.3 Installation position and space requirements
Installation site requirements
Only to be installed within a building where the ambient conditions are
permissible
No direct sunlight
Take into account the additional space required by and the need to access the
following:
– External power unit and batteries
– Blowing-out unit (optional)
– Water trap (optional)
The aspirating smoke detector can be installed either horizontally or vertically
on a level surface.
The dust load should be low at the installation site, because the aspirating
smoke detector housing is opened for maintenance purposes.
Ensure that there is at least 150 mm of free space on each side of the installed
aspirating smoke detector to ensure the pipe system and electrical connections
can be installed with ease.
Connecting to the pipe system
The aspirating smoke detector can be installed in different installation locations.
The installation location to be used depends on the pipe system's connection to the
aspirating smoke detector.

Installation position and space requirements
Four connection types are possible:
Standard: From above (A)
From below (B) when the aspirating smoke detector is installed rotated by 180°
From left (D) or right (E) when the aspirating smoke detector is installed
horizontally
When the aspirating smoke detector is installed horizontally, no adapted
alignment of the front panel is possible. See 'Adapting the front indicator to the
installation position'.

External power unit and batteries
2.4 External power unit and batteries
External power unit
The aspirating smoke detector must be supplied with electricity by an external
power unit. The power unit must satisfy the following requirements:
Version according to EN 54-4
Output voltage: DC 24 V
Output current: 250 mA
The power unit must be connected to the aspirating smoke detector with as
short a cable as possible.
Suitable power unit:
Company
Type
VdS
For battery type
Siemens FP120-Z1 G214130 2x FA2003-A1 (12 V, 7 Ah)
Or
2x FA2004-A1 (12 V, 12 Ah)
Or
2x FA2005-A1 (12 V, 17 Ah)
You will find more information on the power supply kit FP120-Z1 in
document A6V10393194. See the 'Applicable documents' chapter.
Batteries
If the power supply via the external power unit fails, the power supply of the
aspirating smoke detector must be guaranteed using batteries.
If the aspirating smoke detector is in standalone operation: Observe local
regulations for the minimum detector operation period for power supply failure.
The capacity of the batteries must be selected according to the local
regulations.
If the aspirating smoke detector is being operated on a FDnet/C-NET detector
line: The capacity of the batteries must match the runtime of the connected fire
detection installation if the power supply fails. Observe local regulations for the
fire detection installation.
The batteries are charged using the external power unit. The charging current
for the batteries depends on the battery capacity. You should therefore select
your external power unit to match the batteries' capacity.

Fastening on a level substructure
3.2 Fastening on a level substructure
A drilling template is punched in the inner packaging of the aspirating smoke
detector packaging.
The punched symbol in the center of the packaging indicates the airflow direction
(air inlet and air outlet).
The mounting holes in the back box are not symmetrical, so use the drilling
template.

Using the drilling template
4 screws with a shaft diameter of 5…6 mm and a head diameter of 8…10 mm
are available.
A suitable tool for drilling and screwing is available.
The housing cover is removed and the cable loosened.
The product must be installed on a level, non-combustible base.

NOTICE
Connection between pipe system and aspirating smoke detector
Damage to the pipe system and/or the aspirating smoke detector
●Do not glue the pipe system to the aspirating smoke detector! If the pipe
system has to be separated from the aspirating smoke detector for
maintenance work or repairs, components may be damaged.
The pipe system is installed.
The last 500 mm of the pipe system on the aspirating smoke detector must be
straight, such that flow turbulences can be eliminated before entering the
aspirating smoke detector.
