The ELTSK4 emergency lighting test switch allows manual testing of single point emergency lighting systems by simulating a supply circuit failure. This switch allows four (4) emergency lighting circuits to be wired through a normally closed contactor. The test is initiated by momentarily selecting the Test position on the key selector switch. This energizes the contactor and starts a delay off timer . At the end of the test cycle, power is restored automatically, returning the emergency lighting circuits to normal operation. Momentary selection of Reset during the test cycle will also return the emergency lighting circuits to normal operation.
