PCX power supplies are NOT designed for use with multiple batteries connected.
System load should not exceed the panel power supply output or the maximum load supportable by the battery for the
specified backup time.
The power ratings are based on battery shown in table – but ANY battery capable of supporting the system load for the
required time may be used without affecting these ratings.

In accordance with EN50131-6:2008, the PCX standby times and effective output currents depend
on the Security Grade of the system and how 230V mains missing fault is signalled to the Alarm
Receiving Centre. Power supplies are rated in accordance with the requirements of EN50131-6,
which are related to the maximum battery size that can be accommodated in the housing and vary
according to the grade of the system in which they are installed.
