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
Siemens FP120-Z1
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.
