LS-25 Louroe Electronics 25 Zone Line Supervisor
A 25 zone interface unit used with Louroe Alarming Base Stations(ALA-4/8 and DG-12/25 Series). It supervises the current running between the remote microphone and the base station, and detects disruptions such as short circuits, disconnections, or cut wires. When a disruption in current occurs, a lighted LED with a buzzer alarm identifies the problem zone. LS-25 fits a standard 19" rack mount.
