Explanations for Fig. 1:
F1 slow-blow fuse 3.15 A – AC circuit protection.
LEDs indicating present status of the power supply:
– red LED indicating current overload of the power supply:
OFF – current consumption not exceeding 4 A,
blinking – current consumption exceeding 4 A.
– yellow LED indicating the battery status (battery testing mode enabled):
ON – battery OK (or the battery testing mode disabled),
blinking – low battery (battery voltage below 11.5 V),
OFF – no battery or blown F3 fuse (3.15 A).
– green LED indicating the AC mains power supply status:
ON – AC power OK,
blinking – no 230 V AC power or blown F1 fuse (3.15 A).

3. 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).
2 battery test
Enables (ON) / disables (OFF) the battery testing mode. Setting the OFF
position will also disable the battery trouble indication on the WB output.
3 battery charging current
Defines the battery charging current (ON – 1 A, OFF – 0.5 A).

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.
Do not charge the battery with current exceeding 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 V AC 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).
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 2, the battery should provide 12 hours of system operation in
the event of mains power loss.
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.
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:
3 A, if a battery is connected to the power supply,
4 A, if no battery is connected to the power supply.
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,
connect the dedicated cable to the connector designated in Fig. 2.
5. Connect cables 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. Remove the screws and take out the wire fastening
element.
9. Run the cable through the cable grommet.
10.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).

11.Screw the wire fastening element.
12.Replace the cover of power supply terminals.
13.Replace the screw fastening the cover of power
supply terminals.
14.Connect the battery to the dedicated leads (positive terminal to RED one, negative
terminal to BLACK one).
15.Turn on 230 V AC power. The power supply will signal voltage presence with 1 beep and
the LED will go on.
If the event of a ground fault of power supply output (due to installation mistake or
cable defect) or a short circuit caused by failure of the fuse F3 in the battery circuit, the
power supply will turn off. After the problem is cleared, the power supply will turn on
automatically.
5. 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.
