SATEL APS-612 5
The used batteries must not be discarded, but should be disposed of in
accordance with the existing rules for environment protection.
The power supply should be permanently connected to the 230 V AC mains supply. Before
you make the cabling, familiarize yourself with the electrical installation of the facility. Make
sure that the circuit you choose for powering will be always alive. The power circuit should be
protected with a proper safety device. The owner or user of the alarm system should be
instructed on how to disconnect the power supply from the mains (e.g. by indicating the
power circuit breaker).
As the emergency power supply source, use a 12 V sealed lead-acid battery. The battery
capacity must be appropriately selected to match the current consumption in the system. If
the power supply is to be used in an alarm system which is to meet requirements of the
EN 50131 standard for Grade 3, the battery should provide 30 hours of system operation in
the event of mains power loss. On the other hand, the power supply should enable such
a battery to be charged up to 80% of its capacity within 24 hours. Table 3 contains
information on what current must be used for charging batteries of different capacities so as
to meet the requirements of EN 50131 for Grade 2 and Grade 3.
The minimum battery capacity must be 7 Ah. If the capacity is lower, the power supply
will report a trouble when the battery testing mode is started.

If the battery voltage drops to 10.5 V, the power supply unit will turn off to protect the
battery against deep discharge and damage.
Before proceeding to installation, estimate the current consumption by all devices which are
to be supplied from the APS-612 power supply unit. The sum of currents consumed by these
devices must not exceed 3 A.
1. Remove the screw fixing the cover of power
supply terminals.
