GENERAL DESCRIPTION
Control Module, Model EM-1SRI, is used to switch an external power supply or audio amplifier to notification appliances. In addition to switching the external power, the device will monitor the wiring (while external power is not switched to the auxiliary devices) to the auxiliary device for open and short circuits via an end of line resistor. The control module will also have the capability to monitor the external power input for loss of power (DC voltage supplies only). This feature can be disabled through device configuration programming. If the external power is switched to the auxiliary devices and there is a loss of the DC supply, the control module has the capability of running an algorithm in which the device will switch back to monitor mode and check the line for short circuits.
