I NSTALLATION I NSTRUCTIONS
Wirin methods shall be in accordance with the National Electrical Code/NFPA 70/NFPA 72/ANSI, and with all local
codes and authorities havin jurisdiction. Use a minimum spacin of 0.25” between power limited and non-power
limited wirin . This unit is only suitable for installation as permanently connected equipment. This PSU is NOT
SUITABLE for external installation. This unit must be fed from a mains power source havin a separate (approved)
disconnect device and fitted with a fuse or other over-current protection device rated at 15A maximum.
Ensure that the disconnect device used has appropriate earth fault protection to the applicable standard.
EQUIPMENT MUST BE EARTHED. Before installation or servicin , ensure that external disconnect device is OFF.
Mounting
1) Mount securely in a suitable enclosure with the correct orientation allowin minimum clearance – see Figure 1
2) Route mains and low volta e output cables via different knockouts and/or cable entry holes.
3) Use bushes and cable lands rated to UL94 HB minimum.
•
Secure all field wiring exiting enclosure with cable ties.
•
Protect field wiring exiting enclosure using knockouts with
bushes or similar.
•
Use conduit for all Class 1 and non-Class O/Ps field wiring
exiting enclosure.
•
Minimum s acing of 0.25” (6.4mm) between ower limited and
non- ower limited wiring.

Mains Power Up
4) Attach correctly rated mains cable (minimum 2.5mm
2
[15A], 300/500Vac). Fasten with cable ties.
5) Apply mains power. Check for 13.8Vdc on load outputs and Green Mains LED is ON.
6) Disconnect mains power.
Loa Output
7) Attach correctly rated load cable and fasten usin cable ties. Note polarity.
8) Apply mains power.
Check Green Mains LED is ON.
NOTE: Red Fault LED may flash to indicate no battery has been connected, this is normal.
Verify load is operatin correctly.
9) Disconnect mains power.
Signalling
10) Connect EPS and GEN fault outputs to appropriate inputs of Access Control or Indicatin Equipment.
Wirin to “EPS” and "GEN" should be less than 98.5ft (30m) in len th from controller.
Stan by Battery
11) Attach supplied battery cables to terminal block before connectin the battery.
NOTE: ensure correct polarity of battery connections: +ve use Re lead, -ve use Black lead.
Fire Relay Configuration
12) See “OUTPUT FIRE RELAY OPERATION” - Typical Application below.
Tamper
13) Connect tamper switch to appropriate inputs of control and indicatin equipment.
14) Close the lid and fasten with screw supplied.
15) With the unit mounted on the wall check that the rear tamper is not in a position that will affect its operation,
for example over a mortar course, recess or raised area on the wall.
Check that the tamper switch is:
•CLOSED when the lid/cover is closed, and the retainin screws are fitted.
•OPEN when the retainin screws are removed, and the lid/cover is open.
Use the fine adjustment screw if necessary, to ali n indicator with set point.
16) Close the lid/cover and fasten. Re-check tamper circuit is closed at the control panel.
O PERATING I NSTRUCTIONS
In the event of loss of AC mains, a battery fault or a GEN fault, the correspondin Fault si nal contacts will open (see
Fault dia nostic table for LED indicator status).
If the output of the PSU fails, the cause of the failure should be investi ated e. . short circuit load, connection of a
deeply dischar ed battery. The fault should be rectified before restorin power to the PSU. If any of the fuses require
replacin , ensure the correct fuse ratin and type is used.
O UTPUT F IRE R ELAY O PERATION
The power module Fire Relay functionality ives the installer the choice of continuous or switch external control of the
PTC fused Class 2 outputs, by the means of either a Volt Free contact (N/O or N/C) or a low volta e si nal

Typical Application:
Power must be removed from certain parts of the system in the event of a Fire Alarm activation, i.e. door lock power
removed whilst Auxiliary Control Unit (ACU) equipment remains powered.
F IRE FOM C ONNECTIONS & J UMPERS
TRIG: + Tri er I/P from control device (+VE or Contact)
- Tri er I/P from control device (0V or Contact)
Note: Wirin to “TRIG” should be less than 98.5ft (30m) in len th from controller
Note: Fail safe mo e shall be employe in UL294 applications
In case of fail secure configuration, panic har ware shoul be employe to allow exit from secure location.
Contact local authorities having juris iction.
The device has 3 modes of tri er (TRIG) operation set by the on-board jumpers:
Contact Mode (NO) - Jumper across: 2 & 3 FAIL SAFE
Contact Mode (NC) - Jumpers across: 1 & 2 and 3 & 4 FAIL SECURE
Volta e Mode - Jumper across 3 & 4 FAIL SAFE
Each output (O/P) can then be set usin the jumpers next to the relevant fuse:
Output (O/P) a
lways ON (+V)
Output (O/P) Isolated on TRIGGER (Relay)
Note: Removing the jumper completely, will disable the output (no output).
able 1 below defines the output state for the Normal Closed and “Normal Open Contact Modes with rigger
( RIG) selection.
* Note: Tri er Input terminals (TRIG) + and - are polarity conscious when used in Volta e Mode only.
** In Volta e Mode the “+V Applied” can be used with volta es between 10.0V to 28.4V.
Typical Fire Relay Fail-Safe Setup for a Fire Panel Alarm:
In this example the power to the access control lock is FAIL-SAFE when the Fire Panel alarms, or O/P power is
removed.
