Description ELP LM240D LED maintained DALI/Self-Test emergency control gear The ELP LM range provides maintained (mains and emergency) operation of single high power LEDs (or up to 4 connected in series). The LM range can be connected to a DALI system, or can function in a stand-alone Self-Test mode. The control gear incorporates an LED driver circuit, integral charger and a high temperature Nickel Cadmium battery. In the event of a mains failure, the control gear operates the LED (or string of LEDs) at the full light output, for a duration of 3 hours. The LM range can switch the high power LEDs on and off in mains operation using the switch live input, the range is also DALI switchable in mains operation, if the switched live is present. The LM control gear is designed for ease of installation offering compact dimensions and push wire terminals. They are also available with cable restraints providing an ideal solution for independent control gear. In Self-Test mode the function and duration tests will take place at randomised times. NB: 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. https://www.elp.uk.com/
