In case of power failure, a battery back-up is activated immediately.. The PSU is housed in a metal enclosure
(colour RAL 9003) which can accommodate a battery. A micro switch indicates door opening (front cover).
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=Q
AKU
/12 - I
Z
gdzie:
Q
AKU
– minimum battery capacity [Ah]
I
z
– PSU current consumption (including optional modules) [A] (Table 4)
Power supply should be configured to work in intruder alarm systems or access control,
depending on application. For this purpose, appropriate charging current should be selected
(taking into account battery capacity and required charging time).
