2 APS-612 SATEL
The APS-612 switching power supply is designed for powering 12 VDC devices. It is
provided with a connector for integration with SATEL devices. The power supply meets the
requirements of EN 50131 Grade 3.
If the power supply is to be integrated with the devices specified below, make sure
their firmware version is at least:

connector for integration with a SATEL device provided with a connector of the same
type. It is used to power the device and send information about the power supply status.
The connecting cable is included in the set (Fig. 4).
DIP-switches. Used to configure the power supply (see: “Configuration”).
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 high operating temperature.

SATEL APS-612 5
WS –OC type output signaling 230 VAC power loss.
WB –OC type output signaling low battery (voltage below 11.5 V or too high internal
resistance of the battery).
WP –OC type output signaling power output overload (current consumption above 3 A).
COM –common ground.
+12V –+12 VDC power output.
Outputs
In the normal state, the OC type output is shorted to common ground (0 V). In the active state
(trouble signaling), the output is disconnected from common ground (high impedance).
As required by Grade 3, the power output is protected against overvoltage. This is to protect
the devices connected to the power supply. The output overvoltage may be caused e.g. by
installing devices with power on or by unprotected inductive elements in the installation, like
relays, etc. It may result in blowing the fuse in the battery charging circuit or switching the
power supply to the emergency mode.
3. Configuration
Use DIP-switches to configure the power supply settings.
The switch 6 must be set in OFF position.
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.
Switches 4 and 5 –AC power failure reporting delay: see table below.

It is recommended that you activate the battery testing mode for continuous monitoring
of the emergency power supply. The battery test has no effect on the +12V power
output voltage (it remains stable).
The AC power failure reporting delay set in the power supply will be ignored, if the
power supply is integrated with an expander that has been identified as an expander
with power supply. The delay must be programmed in the expander settings.
4. Installation
Disconnect power before making any electrical connections.
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 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 VAC mains power. 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 source, use a 12 V sealed lead-acid battery or other 12 V battery
with similar charging characteristics. Match the battery capacity to the current consumption of
the connected devices. If the battery is to meet the requirements of the EN 50131 standard
for Grade 3 / Grade 2, read section “Standard requirements for battery”.
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 there is no mains power and the battery voltage drops to 10.5 V, the power supply
will turn off to protect the battery against deep discharge and damage.
Before you proceed to installation, estimate the current consumption by all devices which are
to be powered from the APS-612 power supply. The sum of currents consumed by these
devices must not exceed 3 A.
1. Remove the cover of power supply terminals (Fig. 5).
2. Use the DIP-switches (see Fig. 2) to configure the power supply.
3. If the connector for integration is to be used, connect to it the cable shown in Fig. 4
(Fig. 6).
4. If screw terminals are to be used for powering the 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 e.g. LEDs to the trouble signaling outputs or you can connect these
outputs with control panel zones.
7. Run the 230 VAC power cable through the cable gland (Fig. 8).
8. Screw the 230 VAC power wires: 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: 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 no LED is turned ON after powering on, this may suggest that the power output has
been shorted to common ground or there has been a voltage spike. The power supply
enters the emergency mode then.

5. Standard requirements for battery
If the alarm system is to meet the standard requirements for Grade 3, the power supply
battery should ensure 30 hours of device operation. The power supply should be able to
charge the battery to 80% in 24 hours.
If the alarm system is to meet the standard requirements for Grade 2, the power supply
battery should ensure 12 hours of device operation.
See table below for information on what current should be used for charging batteries of
different capacities according to Grade 3 or Grade 2 requirements.

6. Battery testing
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. A full battery test cycle is up to 12 minutes. If the battery voltage
drops below 11.5 V, the LED will start flashing and the WB output will be activated
(optionally, the trouble may be audibly signaled).
