F EATURES
High efficiency cost effective power supply ideal for use in Fire, Access Control and General Security
applications. Featuring a regulated 2 .6Vdc output supplying continuous full rated current to load and up to
an additional 0.5A for charging 2 x 12V standby batteries. Maximum battery life is assured using Deep
Discharge Protection to prevent premature battery failure when operating in standby mode for extended
periods. Two sets of volt-free contacts are provided to signal (i) loss of mains and (ii) battery and loss of
output faults. The universal mains input voltage enables the power supply to be used across a wide
geographical area. The highly efficient switch mode design ensures low operating costs while generating less
heat. The modular construction simplifies maintenance.

O PERATION
This unit is intended for use by Service Personnel only - There are NO USER SERVICEABLE parts inside.
The Green Mains LED will be illuminated whilst the mains supply is present. In the event of a fault condition,
the Yellow Fault LED will be illuminated. The Orange Battery Charging LED will be illuminated when the
battery is not fully charged and is charging normally. When the battery is fully charged it will be
extinguished.
I NSTALLATION AND S ET -U P
This unit is only suitable for installation as permanently connected equipment. The PSU is NOT SUITABLE for
external installation. EQUIPMENT MUST BE EARTHED. Before installation, ensure that external disconnect
device is OFF. The PSU should be installed according to all relevant safety regulations applicable to the
application.
Module Enclosure & Mounting
This power supply module has high voltage present and is for use by Service Personnel only. This power
supply module MUST be securely mounted within a robust enclosure having suitable means to prevent
unintentional access to the module. Suitable notices must be affixed to the outside of the enclosure to warn
of high voltages present internally.
Mounting
1) Mount securely in correct orientation allowing minimum clearance of 20mm all round – see diagrams
below.

Mains Power Up
3) Attach correctly rated mains cable (minimum 0.5mm
2
[3A], 300/500Vac) and secure in enclosure using
cable ties.
4) Apply mains power. Check for 2 .6Vdc on load outputs. Check Green Mains LED is on.
5) Disconnect mains power.
Load Output
6) Attach correctly rated load cable and secure in enclosure using cable ties. Note polarity.
) Apply mains power. Check green Mains LED is on.
8) NOTE: Yellow Fault LED may flash to indicate no battery has been connected; this is normal.
9) Verify load is operating correctly.
10) Disconnect mains power.
Signalling Outputs
11) Connect EPS and GEN fault outputs to appropriate inputs of control equipment.
Standby attery
12) Connect battery to terminal block using minimum 32/0.2 (1.0mm
2
CSA) stranded wire.
NOTE: ensure correct polarity of battery connections. Maximum recommended total battery lead
length = 500mm
13) Apply mains power. Check Green Mains LED is ON. Check Orange Charging LED is ON.
14) Check there is no fault indication on Yellow LED.
15) Disconnect mains power. Check that the batteries continue to supply voltage and current to the load.
Check Green Mains LED is OFF and the control panel displays a Loss of Mains (EPS) fault
NOTE: Batteries must have sufficient charge to supply the load
16) Reconnect mains power. Green LED should be on.
1 ) Remove Load fuse. Check Yellow Fault LED is ON and control panel shows General PSU fault.
18) Replace Load fuse. Check Yellow Fault LED is OFF and General PSU fault has cleared at control panel.

M AINTENANCE
There is no regular maintenance required of the PSU other than periodic testing and replacement of the
standby batteries. Reference should be made to the battery manufacturer’s documentation to determine
typical/expected battery life with a view to periodic replacement of the battery.
If the output of the PSU fails the cause of the failure should be investigated e.g. short circuit load. The fault
should be rectified before restoring power to the PSU. The fuses may need to be replaced. Ensure the
correct fuse rating and type is used.
