F EATURES
High efficiency cost effecti e power supply ideal for use in Fire, Access Control and General Security applications.
Featuring a regulated 27.6Vdc output supplying continuous full rated current to load plus additional current for
charging 2 x 12V standby batteries. Maximum battery life is assured using deep discharge protection to pre ent
premature battery failure when operating in standby mode for extended periods. Two sets of olt-free contacts are
pro ided to signal (i) loss of mains and (ii) battery and loss of output faults. The uni ersal mains input oltage enables
the power supply to be used across a wide geographical area. The highly efficient switch mode design ensures low
operating costs, generates less heat and with a small physical size increases the room a ailable for additional PCBs or
cables. The modular construction simplifies maintenance.

I NSTALLATION I NSTRUCTIONS
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 ha ing a separate (appro ed) disconnect de ice and fitted
with a fuse or other o er-current protection de ice rated at 3A maximum. Ensure that the disconnect de ice used has
appropriate earth fault protection to the applicable standard. EQUIPMENT MUST BE EARTHED. Before installation,
ensure that external disconnect de ice is OFF.The PSU should be installed according to all rele ant safety regulations
applicable to the application.
Mounting
1) Mount securely in correct orientation allowing minimum clearance – see diagram.
2) Route mains and low oltage output cables ia different knockouts and/or cable entry holes.
3) Use bushes and cable glands rated to UL94 HB minimum.
Mains Power Up
4) Attach correctly rated mains cable (minimum 0.5mm
2
[3A], 300/500Vac). Fasten with cable ties.
5) Apply mains power. Check for 27.6Vdc on load outputs. Check Green Mains LED is ON.
6) Disconnect mains power.

Load Output
7) Attach correctly rated load cable and fasten using cable ties. Note polarity.
8) Apply mains power. Check Green Mains LED is ON.
9) NOTE: Yellow Fault LED may flash to indicate no battery has been connected. This is normal.
10) Verify load is operating correctly.
11) Disconnect mains power.

Signalling Outputs
12) Connect EPS and GEN fault outputs to appropriate inputs of control equipment.
Standby Battery
13) Attach supplied battery cables to terminal block and batteries. NOTE: ensure correct polarity!
Red lead to + e of battery 1, Black lead to - e of battery 2.
Connect - e of battery 1 to + e of battery 2 using short link lead
14) Apply mains power. Check Green Mains LED is ON and Orange Charging LED is ON
15) Check there is no fault indication on Yellow Fault LED.
16) Disconnect mains power. Check that the batteries continue to supply oltage 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 ha e sufficient charge to supply the load
17) Reconnect mains power. Check Green Mains LED is ON.
18) Remo e Load fuse and check Yellow Fault LED is ON and control panel shows a General PSU fault.
19) Replace Load fuse. Check Yellow Fault LED is OFF and General PSU fault has cleared at the 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 in estigated 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.
