Installation & User Manual
LPS-12-G2 / LPS-12-G3 / LPS-ENC-T
INTRODUCTION
This manual covers the Grade 2, Grade 3 and a Tamper only variant of the Li-Power
Intruder approved product. This power supply unit has been designed to house common
alarm communicators providing compliant, reliable
power to the chosen device.
Provided with a Lithium battery pack (Grade 2 and 3
variants) it ensures the device remains powered in the
event of a mains failure. The Integrated Intelligent
Battery Management features provide active battery
testing, low battery voltage detection and deep
discharge protection to ensure that the battery is kept
in optimal condition. It also has a range of
comprehensive self-diagnostics, including thermal
cut-off protection. Except the Tamper only variant, the
remainder of this manual gives details on the LPS-12-
G2 and G3 products.
EN50131-6 approved product. Grade 2 and 3 variants contain Li-ion batteries.
FEATURES
•Provides continuous current to load for systems requiring 12Hrs (Grade 2) or 30Hrs
(Grade 3) standby from the supplied battery pack as specified in EN50131.
•Flame retardant (UL94 V0) hinged enclosure with screw lock lid.
•Front / rear tamper detection.
•Can be securely wall mounted.
•Cable ingress/egress management facilitated via breakout features on three sides as
well as pilot drill points located around the periphery of the enclosure.
•Independent output signals indicate loss of AC power, battery and power supply fault.
•Inbuilt charger and monitoring circuits ensures safe battery operation.
•Intelligent battery management comprises active load battery testing, low battery
voltage detection and deep discharge protection to ensure that the battery is not
permanently damaged through excessive discharge.
•Comprehensive self-diagnostics with internal LED status indications
•Product includes AC power transient filtering, electronic output overload protection
and fuses for the load and battery outputs.
Refer to the enclosed Safety Sheet before installation and first use.
SAFETY INFORMATION

Technical Support: [phone] PAK200967_02A ©2023 ELMDENE INTERNATIONAL LTD
Once installed and commissioned no further involvement is required for normal
operation. Under normal conditions with AC mains applied, the power supply will provide
a continuous load current of up to 150mA whilst the intelligent battery management
automatically charges, tests and maintains the installed battery pack. Should a fault
occur, the relevant fault signal will be activated, and in-built diagnostic LEDs will provide
additional information regarding the type of fault detected. The unit will continue normal
operation once the fault has been rectified.
Should a loss of mains occur, the unit will flag a fault and seamlessly switch to the battery
pack for power, with the unit capable of running for up to 30hrs (dependent on load and
battery pack installed). Should the battery pack become depleted before mains power is
re-applied the Alternative Power Supply (APS) fault will be flagged to indicate battery
power is very low, occurring a few minutes (dependent on load, battery pack and other
conditions) prior to the battery pack disconnecting and all power to the load being
dropped.
Once mains power has been restored, power to the load from the power supply will
automatically be provided and the battery pack will start to be recharged as required
(subject to environmental conditions).
For monitoring, three independent output signals are provided to indicate, loss of AC
power fault (EPS), battery fault (APS), and power supply fault (GEN).
Comprehensive self-diagnostics give detection of:
•blown output fuse
•battery disconnection
•battery fault
•low battery voltage
•low output voltage
•battery charger only operational between 3°C and 50°C
Monitoring functions are described in the Signalling Outputs section.
Comprehensive protection is built-in as standard to include:
•AC power transient filtering
•electronic output overload protection
•fuses on the load and battery outputs
•deep discharge protection
•brownout filter to prevent false loss of AC power fault (10 seconds)
OPERATION AND MONITORING OVERVIEW

INSTALLATION AND COMMISSIONING
This unit is only suitable for installation as permanently connected equipment and is to
be used with DC appliances only. This equipment is NOT SUITABLE for external
installation and must be installed according to all relevant safety regulations.
PSU internal components
The unit must be fed from an AC power source having a separate (approved) disconnect
device and fitted with a fuse or other over-current protection device rated at 3A
maximum. Ensure that the disconnect device used has appropriate earth fault protection
to the applicable standard.
1) Mounting
a) Remove battery and bungee. Mount securely at 3 positions allowing minimum
clearance of 10cm from walls, ceilings or other obstacles.
b) Route power and LV cables via different knockouts / cable entry holes.
c) Use bushes and cable glands rated to UL94 HB minimum.
2) AC Power Up (commissioning)
a) Attach correctly rated AC power cable and fasten using cable ties.
b) Apply AC power. Check for 12Vdc on load outputs and AC power LED is on.
c) Disconnect AC power.
3) Load Output (commissioning)
a) Fit battery in compartment using self-adhesive tape and bungee provided.
b) Attach supplied battery to the connector B1 (BATT).
NOTE: ensure correct polarity of battery connections.
c) Apply AC power. Check AC power LED is on.
d) Check there is no fault indication on the Fault LED. A single short flash indicates the
battery is charging, please note, this is normal operation.
e) Disconnect AC power. Check that the battery continues to supply voltage and
current to the load.
f) Reconnect AC power.
4) Tamper
a) Connect tamper switch to Control & Indicating Equipment (CIE) inputs.
b) Check that the CIE recognises the tamper is ‘OPEN’.
c) Close the lid and check that the CIE recognises the tamper is ‘CLOSED’.

CONNECTIONS
The figure below shows product connections.
+, − Connections for equipment to be powered (Observe polarity).
BATT Connection to the battery pack.
APS FAULT Relay output for battery fail. Open if battery fail or open for low output
or temperature fault - Normally Closed when Healthy.
EPS FAULT Relay output for AC power fail. Open if loss of AC power - Normally
Closed when Healthy.
GEN FAULT Relay output for General Fault. Open in fault condition - Normally
Closed when Healthy.
TAMPER Front & Rear Enclosure Tamper signal –Normally Closed when Healthy.
In the event of loss of AC power, a battery fault or a PSU fault, the corresponding fault
signal contacts will open.
If the PTC output fuse is triggered it will automatically reset once the defect is removed.
