ABSTRACT:
A testing device for emergency lighting units has a telescopic handle, a bracket at a first end of the handle, a magnet at the end of the bracket and a temperature sensor adjacent to the magnet. The magnet has sufficient strength to engage a surface of the lighting unit adjacent a test switch so as to cause actuation of the test switch. The magnet holds the test switch down for the duration of the test. The temperature sensor provides an indication of the ambient conditions adjacent the lighting unit which has an effect on battery life and which is used to determine the frequency of the testing of the unit.
