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
** General use – if the PSU is not mounted in an installation complaint with the EN-50131 standard, the
acceptable current efficiency amounts to:
Total current of the receivers + battery charging current is max. 1A.
In case of power decay, a battery back-up is activated immediately. The PSU is housed in a metal
enclosure with battery space for a 7Ah/12V battery. It is fitted with micro switches indicating unwanted door
opening (front panel).
