Description

The Potter Electric SCM-4 is a contact module that supervises a circuit of dry-contact input devices such as sprinkles water flow, valve tamper switches, and conventional pull stations. In addition, the SCM-4 module uses one address on an SLC loop. The SCM-4 module includes one red LED to indicate the status of the module. In normal conditions, the LED flashes when the device is being polled by the control panel. Then, when a device is activated, the LED will light continuously. In the case of an open circuit, the LED will turn off.
