aps-612_en 03/17
The APS-612 switching power supply has been designed for use with 12 V DC electrical
devices. It comes with a dedicated connector allowing for integration with Satel's devices.
The power supply can be integrated with the following SATEL devices (required

According to Standard EN 50131 for Grade 3, the power supply has overvoltage
protection on the power supply output. It provides protection for devices connected to
the power supply unit. Overvoltage on the output (caused by installing devices with the
power on, unprotected inductive elements in the installation, like relays, etc.) may
result in blowing the fuse in the battery charging circuit or the power supply entering
the emergency mode.
2. Description of the power supply
F2 slow-blow fuse 3.15 A – battery charging circuit protection.
F1 slow-blow fuse 3.15 A – AC circuit protection.
LEDs indicating present status of the power supply:
– red LED indicating power output satus:
OFF – correct operation, current consumption not exceeding 3 A,
ON – short circuit,
flashing – overload, current consumption exceeding 3 A.
– yellow LED indicating the battery status, if the battery testing mode is enabled:
OFF – no battery or blown F2 fuse (3.15 A),
ON – battery OK,
flashing – low battery (battery voltage below 11.5 V or too high internal resistance
of the battery).
If the testing mode is disabled, the battery is OFF.

SATEL APS-612 3
– green LED indicating the AC power status:
ON – AC power OK,
flashing – no 230 V AC power or blown F1 fuse (3.15 A).
– blue LED which indicates by flashing that the operating temperature rose above
75°C (which may result in damage to the power supply).
If, with the 230 V AC supply connected, all the LEDs are OFF, the power supply must
have entered the emergency mode as a result of the power supply output being shorted
to the common ground (voltage spike) – see section “Installation”.

Description of terminals:
L – terminal for connecting phase conductor.
N – terminal for connecting neutral conductor.
PE – terminal for connecting protective conductor.
WT –OC type output signaling that permissible operating temperature is exceeded.
WS – OC type output signaling 230 V AC power loss.
WB – OC type output signaling no battery, low battery (below 11.5 V) or too high internal
resistance of the battery.
WP – OC type output signaling current overload (above 3 A).
COM – common ground.
+12V – +12V DC power output.
During normal operation of the power supply, the OC type outputs are shorted to the
common ground (0 V), but when trouble occurs, the respective output is disconnected from
the common ground.

2.2 DIP-switches
The switch 6 must be set in OFF position.
The switches 1-5 are intended for setting operating parameters of the power supply (see
Table 1). By factory default, all of them are set in OFF position.
Switch No. Description
1 audible trouble signal
Enables (ON) / disables (OFF) the audible trouble signal (short beep
every 3 seconds).

battery test
Enables (ON) / disables (OFF) the battery testing mode. Setting the OFF
position will also disable the no battery and battery trouble indication on
the WB output.

AC power failure reporting delay
Defines the time that must elapse after the moment of AC power failure
for the WS output to be activated. The delay time shall be set in
accordance with Table 2.
Table 1.
It is recommended that you activate the battery testing mode for continuous monitoring
of the operation of emergency power supply. The battery test is performed irrespective
of the voltage on the 12 V DC power supply output.

Table 2.
If the power supply is connected to the dedicated expander connector and the
expander has been identified as an expander with power supply, the AC power failure
reporting delay set by means of the switches will be disregarded. The delay shall be
programmed for the expander.
3. Installation
Disconnect power before making any electrical connections.
Making connections with the power ON may lead to blowout of the fuse in the
battery circuit or cause the power supply enter the emergency mode. In order to
exit the emergency mode, disconnect the 230 V AC supply and then reconnect it
after about 30 seconds.
The power supply has been designed for use with lead-acid batteries or other
batteries having similar charging characteristics. Using other batteries than the
recommended ones may cause an explosion.

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.

Table 3.
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.

2. Remove the cover of power supply terminals.
3. Configure the power supply using the DIP switches.
4. If the power supply is to be connected to a device provided with dedicated connector, use
the cable delivered with the power supply, to connect the power supply and the device.
5. Connect wires to the +12V and COM terminals, if they are to be used to supply the
external device.
6. You may connect LEDs or relays to the trouble signaling outputs, or connect these
outputs to control panel zones.
7. Connect battery cables to the connector designated in Fig. 2.
8. Run the cable through the cable grommet.
9. Screw the 230 V AC power leads to the
corresponding terminals (phase conductor to L
terminal, neutral conductor to N terminal, and
protective conductor to PE terminal).
10. Screw the wire fastening element.

11. Replace the cover of power supply terminals.
12.Replace the screw fastening the cover of power
supply terminals.
13.Connect the battery to the dedicated leads (positive terminal to RED one, negative
terminal to BLACK one).
14.Turn on 230 V AC power. The power supply will signal voltage presence with 1 beep and
the LED will go on.
4. Battery testing by the power supply
After starting the power supply, provided that the battery testing mode is enabled and
a sufficiently charged battery is connected, the LED should go on. The battery is
checked every 4 minutes. Duration of a full test of the battery charge status is up to 12
minutes. If the battery voltage drops below 11.5 V, the power supply will report a trouble on
the WB output, and the LED will start blinking (optionally, the trouble may be audibly
signaled).
