LDM

LED Array Emergency Control Gear

LDM Range

The ELP ENEC marked LDM emergency LED control gear allows emergency lighting operation of high-power LED modules when used in conjunction with the standard mains voltage LED control gear.

The emergency control gear incorporates a module/charger and a high temperature Nickel Cadmium or Lithium Iron Phosphate (LiFePO4) battery. In the event of a mains failure an integral 2-pole relay disconnects the LED lighting load from the mains control gear and then connects it to the emergency control gear which operates the LED module at an optimum light output for the rated duration.

To ensure the correct operation of each type of LED module the correct LDM equipment should be selected.

The total forward operating voltages of the LED module/arrays connected should be used to determine the appropriate LDM control gear. For the appropriate battery, indicator LED etc., see Order Codes.

Note: All LDM modules can be equipped with SurePath BLE Bluetooth addressable Gateway modules.

Microprocessor Enabled Features

The LED current in emergency mode is automatically adjusted for maximum light output and is constant for the entire rated duration.
Smart charging of both Nickel Cadmium and Lithium Iron Phosphate batteries. NB: Lithium Iron Phosphate batteries offer long life (up to 10 years).
Details are logged of any mains failures to assist in the diagnostics of any site issues.
The LDM range is available with fully interoperable DALI control and reporting function. These DALI versions indicated by the suffix D, also provide automatic Self-Test when no DALI bus is connected.

It is important to note that some LED mains control gear should not be operated with an open circuit load, to overcome this problem the LDM range features a live in/ live out relay which ensures the load is in place before the mains driver is powered up.

In Self-test mode the function and duration tests will take place at randomised times. If required, testing can be programmed to occur at a designated time by turning the unswitched supply off and on 3 times in 10 seconds at the required time. Note: The function test will occur weekly at the same time.
