Product Description:


The Serenity Tendo Emergency lighting module range is designed to convert a wide range of LED fixtures to an emergency feature. The Tendo is suitable for most standard LED luminaires and arrays containing from 2 to 20 LEDs in series (6 to 55V DC).

The Tendo emergency range is designed to be inserted into the low voltage connection between the mains LED driver and LED fixture to allow the LEDs to be operated as normal under mains healthy conditions or at a reduced light output in emergency mode.

The Tendo range automatically adjusts the outputLED current to provide the best match between the battery and the load, providing maximum illumination whilst ensuring full battery duration. The Tendo emergency lighting module is compatible with a wide range of LED emitters and arrays such as Philips Fortimo DLM, SLM and LLM ranges, Bridgelux LS/ES/RS ranges, Citizen 4-41W ranges, GE Infusion, Xicato and many others.

The converter/charger module is housed in a standard HRN sized case and comes complete with 8 way and 4 way terminal blocks. The 8 way allows connection of unswitched 240V supply, irreversible battery connector, charge indicator LED and additional relay terminals to isolate the supply to the associated mains LED driver, whilst the 4 way allows connection of two leads in from the maintaining LED driver, and two out to the LEDs themselves. For complete details on installation and maintenance please refer to product user guide.
