In case of power failure, a battery back-up is activated immediately.
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:
The 12h standby output current can be calculated from the formula:
I=QAKU/12 - IZ
where:
QAKU – minimum battery capacity [Ah]
Iz – PSU current consumption (including optional modules) [A] (Table 3)
To be able to install PSU module in the Intrusion Detection Systems or Access Control
systems, it must be placed in enclosure with an appropriate design and, in order to obtain
certificate, supplementary tests must be commissioned for compliance with EN50131-6: 2017
or EN60839-11: 2013 standards in notified laboratory.
PSU module should be configured properly, depending on application, to work in burglary
and assault signalling systems or access control. For this purpose, appropriate charging
current should be selected (taking into account battery capacity and required charging time).
