3.1 General description.
The buffer power supply is designed in accordance with the requirements of the EN 50131-6 standard,
grade 1÷3 and II environmental class. It is intended for an uninterrupted supply of alarm system devices requiring
stabilized voltage of 12 V DC (+/-15%).
Depending on a required protection level of the alarm system in the installation place, the PSU efficiency
and the battery charging current should be set as follows:
* Grade 1, 2 - standby time 12h
Output current 1,4 A + 1,5 A battery charge
** Grade 3 - standby time 30h if the faults of the main power source are reported to the Alarm Receiving
Centre - ARC (in accordance with 9.2 – EN 50131-1 standard).
Output current 0,56 A + 1,5 A battery charge
- standby time 60h if the faults of the main power source are reported to the Alarm Receiving
Centre - ARC (in accordance with 9.2 – EN 50131-1 standard).
Output current 0,28 A + 1,5 A battery charge
*** General use – if the PSU is not mounted in an installation complaint with the EN-50131 standard, the
acceptable current efficiency amounts to:
1. Output current 3 A + 0,2 A battery charge
2. Output current 2,6 A + 0,6 A battery charge
3. Output current 2,2 A + 1 A battery charge
4. Output current 1,7 A + 1,5 A battery charge
Total current of the receivers + battery: 3,2 A max.
In case of power decay, a battery back-up is activated immediately. The PSU is housed in a metal
enclosure (color: RAL 9005 - black) with battery space for a 17 Ah/12 V battery. It is fitted with micro switches
indicating unwanted door opening (front panel) and detachment from the mounting surface.
