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

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.
