LDR

Remote Emergency Conversion Kit

The LDR emergency LED remote (independent) control gear allows maintained operation of high-power LED modules, and has been designed to be used in applications where you cannot fit an emergency conversion kit inside the luminaire, making it ideal for 600×600 panels and downlights where the pack can be positioned in the ceiling void. With colour coded push fit terminals, cable restraints and terminal covers it makes this a safe and installation friendly product for luminaires that need a remote pack solution.

The LDR emergency control gear incorporates a module/charger and a high temperature Lithium Iron Phosphate battery all in one housing. 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.

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 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 LDR 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.

In Self-test mode the function and duration tests will take place at randomised times. If required, duration testing can be programmed 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.

LDR EMERGENCY CONTROL GEAR

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

The total forward operating voltages of the LED module/arrays connected should be used to determine the appropriate LDR control gear. For the appropriate battery, indicator LED etc., see Order Codes. Note: All LDR modules can be equipped with SurePath BLE Bluetooth addressable Gateway modules.
