Installation Instructions:
The units should be installed in accordance with article 760 of The National Electrical Code and NFPA 72 as well as all
applicable Local Codes.
See Terminal Identification Chart on page 2 for a description of each terminal function.
1. Mount unit in the desired location. Mark and predrill holes in the wall to line up with the top two keyholes in the
enclosure. Install two upper fasteners and screws in the wall with the screw heads protruding. Place the enclosure’s
upper keyholes over the two upper screws; level and secure. Mark the position of the lower two holes. Remove the
enclosure. Drill the lower holes and install two fasteners. Place the enclosure’s upper keyholes over the two
upper screws. Install the two lower screws and make sure to tighten all screws (Enclosure Dimensions, pg. 4).
2. Power connections: Connect secondary (blue and yellow leads) from the transformer to the Power Supply Board
terminals marked [XFMR] (Fig. 1 - Board Installation Diagram, pg. 3). Connect 220VAC 50/60Hz to the black and
white flying leads of the transformer. Secure green wire lead to earth ground. Use 18 AWG or larger for all power
connections (Battery, AC input, DC outputs). Use 22 AWG to 18 AWG for power limited circuits (Trigger inputs,
Dry outputs, DC outputs).
3. Measure output voltage before connecting devices. This helps avoiding potential damage.
4. Set the desired DC output voltage by setting switch SW2 to the appropriate position
(Power Supply Output Specifications Table, pg. 1, Fig. 1a, pg. 3).

Overview:
AL125220 and AL125X220 are power supply/chargers that convert 220VAC 50/60Hz input into two individual PTC
protected 12VDC or 24VDC outputs (see specifications).

5. Connect Fail-Safe locking devices to the terminals marked [COM-- and LOCK+]. Connect Fail-Secure locking
devices to the terminals marked [COM-- and STRIKE+] (Fig. 2, pg. 3).
6. Connectnormallyopenaccesscontroldevice(i.e.cardreader,requesttoexitdevice,accesscontrolsystem)tothe
terminals marked TRG INPUT [NO, GND] (Fig. 1 - Application Diagram, pg. 3).
7. Connect FACP interface to the terminals marked [FACP1 and FACP2]. Wire the 2.2K resistor (supplied) in series
for a normally closed input or in parallel for a normally open input (Fig. 1, pg. 3). If required, set the latching FACP
interface mode by closing SW1 (Fig. 1a, pg. 3), and connect a normally open reset device to the terminals marked
RESET [NO, GND].
8. Connect battery to the terminals marked [+ BAT -- ] (battery leads included). Use two (2) 12VDC batteries connected
in series for 24VDC operation.
Note: For Access Control applications batteries are optional. When batteries are not used, a loss of AC will result in the
loss of output voltage. When the use of stand-by batteries is desired, they must be lead acid or gel type.
9. Please ensure that the cover is secured with the provided cam lock.
Maintenance:
Unit should be tested at least once a year for the proper operation as follows:
Output Voltage Test: Under normal load conditions, the DC output voltage should be checked for proper voltage level
(Power Supply Output Specifications Table, pg. 1).
Battery Test: Under normal load conditions check that the battery is fully charged, check specified voltage both at battery
terminal and at the board terminals marked [- BAT +] to ensure that there is no break in the battery connection wires.
Note:Maximumchargingcurrentunderdischargeis400mA.
Note:Expectedbatterylifeis5years;however,itisrecommendedchangingbatteriesin4yearsorlessifneeded.
