'Lite' Control Testing System

< PREVIOUS | NEXT >

The Lite system provides real-time monitoring and automatic testing of emergency lighting.

It is designed to satisfy the requirements of BS5266 part 1 and prEN50172 standards for emergency lighting systems.

Each Lite control panel supports maintained, non-maintained and slave luminaires in either self-contained, central battery or static inverter systems.

The control panel electronics are housed in a high quality steel enclosure with sealed front label protecting the control keys, LED Indicators and liquid crystal display. The graphic display is backlit to improve visibility in poor ambient light conditions.

The system is modular in construction. For small systems, a single line driver is used to connect up to 249 Pulse Line Unit (PLU) addressable luminaires or I/O modules over a 2-core cable. Each line driver takes the form of a small, plug-in circuit card and each panel can control up to 4 line drivers. Further expansion is easily achieved by networking up to 200 Lite panels.

The installation may be divided up into a maximum of 200 Zones (1000 Zones when networked) to correspond with the building fire zones, with each luminaire capable of being identified by its zone description and individual location description. In addition, the installation may be divided up into 50 Test Groups, per panel, for automatic or manual testing, thereby permitting the testing of alternate luminaires within a zone.

A user-friendly, menu driven software is used to assist in commissioning systems and for general operation of the panel. Once luminaires are connected to the panel, a simple 'Learn' procedure is run to quickly identify the quantity and types connected on each line.

Automatic testing can be carried out at any time of day or night. Flexible programming allows the time, date and duration of test for multiple groups of lights to be quickly specified, with up to 400 unique time / date / periods per year. The panels can be fully on site programmed using the front panel alphanumeric keypad. Alternatively, the panel programming may be configured from a PC via the isolated RS232 serial port.

Alternatively, the data can be transferred to a database on a central PC for subsequent analysis, listing and printing. Remote monitoring is also possible via an internal modem option.

Software running on a remote PC can be set to periodically dial into each panel and check for any faults. Again proof of all tests carried out on each luminaire, showing the time, date and duration of each test can be automatically printed from the PC.

The control panel is compatible with all Pulse Line Units.

Models: Lxp-302, Lxp-304 Light Only, Lxp-110 I/O and Lxp-111 AC Current to Light Converter.

The control panel is also compatible with the AEL-302 (luminaire powered) control/monitor module.

The Pulse Line Unit is a device which checks for correct light levels, AC and battery power and provides the following major features:

• Self (Soft) Addressing - no DIL Switches to set in the luminaire fitting

• Removal of double addressing at the panel - no need to go to luminaire

• Loop powered so does not effect the luminaire battery supply

• AC Mains sensing and control

• Real-time Analogue Light Level Monitoring (via a unique fibre-optic sensor) available at the panel

• Real-time Analogue Battery Level Monitoring available at the panel

The Pulse Light Only Line Unit is a device which checks for correct light levels, but does not monitor a battery or AC supply and provides the following major features:

• Self (Soft) Addressing - no DIL Switches to set in the luminaire fitting

• Removal of double addressing at the panel - no need to go to luminaire

• Loop powered so does not affect the luminaire battery supply

• Real-time Analogue Light Level Monitoring (via a unique fibre-optic sensor) available at the panel

The Pulse Input/Output Line Unit is available to support central battery systems, or any other situation in which additional loop powered inputs or outputs are required and provides the following major features:

• Self (Soft) Addressing - no DIL Switches to set in the luminaire fitting

• Removal of double addressing at the panel - no need to go to luminaire

• Loop powered

• Output Relay to control the central battery / static inverter luminaire test operation

• Input for monitoring of Alarms or Warnings

The Pulse Line Unit provides the following major features:

• AC powered so does not effect the luminaire battery supply

• Senses current drawn by the lamp and converts to a light output for monitoring via the Lxp-302 or Lxp-304 modules.

• Suitable for applications where it is not possible / convenient to monitor the actual light - e.g. tungsten lamps.
