Model DRA-1 Remote Annunciator

The PG LIFELINK Model DRA-1 Remote Annunciator is designed to handle a single isolated power source. When the leakage impedance to ground for the system being monitored is within the predetermined limit, a green light is illuminated. Should this limit be exceeded, a red light illuminates and an alarm sounds. At this point a silencing switch can be depressed to disconnect the signal. As soon as leakage impedance returns to an acceptable level, the unit resets itself automatically.
