Burk Technology TLM

Tower Light Monitor


The TLM is a universal lamp alarm relay designed to sense the failure of flashing or steady incandescent beacon lamps or steady side lights. The toroidal current sensor provides islolation and allows monitoring of more than one line at a time. The TLM energizes when one or more lamps fail. It will monitor the operation of up to four side lights or four beacon lamps.
