2.1 Electronics board
Description of terminals:
L –terminal for connecting phase conductor.
N –terminal for connecting neutral conductor.
PE –terminal for connecting protective conductor.
+12V –+12 VDC power output.
COM –common ground.

4 APS-412 SATEL
WB –OC type output signaling low battery voltage (below 11.5 V).
WP –OC type output signaling power output overload (current consumption above 4 A).
In normal status, the OC type outputs are shorted to common ground (0 V). When trouble is
detected, the output is disconnected from common ground.

connector for integration with SATEL devices. It is used to power SATEL devices and
transmit information on the power supply status. The SATEL device must have the same
connector. The connecting cable is included in the set (Fig. 4).
F3 fuse (T 3.15 A) –protection of battery charging circuit.
DIP-switches. Used for configuring the power supply (see: “Configuration”).
3. Configuration
The switch 6 must be set in OFF position.
Use the switches 1-5 to configure the power supply settings:
Switch 1 –audible trouble signaling: ON=enabled / OFF=disabled.
Switch 2 –battery test: ON=enabled / OFF=disabled.
Switch 3 –battery charging current: ON=1 A / OFF=0.5 A.
The battery charging current must not exceed 10% of the battery capacity.

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.
4. Installation
Disconnect power before making any electrical connections.
The power supply should be permanently connected to the 230 VAC mains supply. Before
you make the cabling, familiarize yourself with the electrical installation of the facility. Select
a circuit which is always alive to supply the unit. The power circuit should be protected with
a proper safety device. Instruct the owner / user of the power supply how to disconnect the
unit from the mains (e.g. indicate the fuse protecting the power circuit).
For a backup power supply, use a 12 V sealed lead-acid battery or other 12 V battery with
similar charging characteristics. The battery capacity must be selected to match the current
consumption in the system. If the power supply is to meet the requirements of the EN 50131
standard for Grade 2, refer to the “Standard requirements for battery” section.
Do not use batteries other than the recommended ones.
Do not connect deeply discharged battery to the power supply (with voltage
across unloaded terminals below 11.5 V). The battery should be precharged with
a proper charger.
The used batteries must not be discarded, but should be disposed of in
accordance with the existing rules for environment protection.
Before proceeding to installation, estimate the current consumption by all devices which are
to be supplied from the APS-412 power supply unit. The sum of currents consumed by these
devices must not exceed:
operation with battery: 3,5 A (battery charging current: 0.5 A) / 3 A (battery charging
current: 1 A),
operation without battery: 4 A.
1. Remove the cover of power supply terminals (Fig. 5).
2. Configure the power supply using the DIP switches (see: “Configuration”).

3. If the connector for supplying power to SATEL devices is to be used, connect to it the
cable shown in Fig. 4 (Fig. 6).
4. If screw terminals are to be used for supplying power to devices, screw the wires to +12V
and COM terminals.
5. Connect the battery wires (Fig. 3) to the connector on the electronics board (Fig. 7).
6. You can connect the trouble signaling outputs with control panel zones, or you can
connect e.g. LEDs to these outputs.
7. Run the 230 VAC power cable through the cable gland (Fig. 8).
8. Screw the 230 VAC power wires to terminals: phase conductor to L terminal, neutral
conductor to N terminal, and protective conductor to PE terminal (Fig. 9).
9. Screw the element fastening the 230 VAC power cable (Fig. 10).
10.Replace the cover of power supply terminals (Fig. 11) and fasten it with a screw (Fig.12).
11.Connect the battery to the dedicated wires (battery positive to red wire, negative –
to black).
12.Turn on 230 VAC power. When the AC power is present, the power supply will signal it
with a single beep sound and the LED turning ON.
If the power output is shorted to common ground or the F3 fuse is defective, the power
supply will turn off.

5. Standard requirements for battery
If the power supply is to be used in an alarm system which is to meet requirements of the
EN 50131 standard for Grade 2, the battery should provide 12 hours of system operation in
the event of mains power loss. Table 2 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.

6. 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 after about 10
seconds. The battery is checked every 4 minutes for ten to twenty seconds. 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). When the voltage goes down to
10.5 V, the power supply will disconnect the battery to protect it against full discharge and
damage. The LED will go off.
