ELMDENE LPS-12-G2 Li-Power Intruder User Manual

LPS-12-G2 / LPS-12-G3

INTRODUCTION

This manual covers the Grade 2 and Grade 3 variants 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 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.

EN50131-6 approved product. Contains 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.

SAFETY INFORMATION

**** Refer to the enclosed Safety Sheet before installation and first use.

OPERATION AND MONITORING OVERVIEW

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)

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.

Figure 1: 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

Figure 2 shows product connections.

Figure 2

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.
