POTTER ADDRESSABLE SINGLE CONTACT MODULE
Product Info
POTTER # 1430820
The SCM-4 module is used to monitor the contact status of a dry contact device (i.e, pull station, waterflow switch, etc) that contains a normally open contact. The SCM-4 can be programmed in the panel to supervise either a Normally-open or Normally-close contact on the Fire Alarm Control Panel (FACP). When the Normally-open contact is selected, and the contact is closed, the SCM-4 reports its condition to FACP. Likewise when the Normally-close contact is set as supervising condition, and the contact is opened, the MCM reports its condition to FACP. SCM-4 supervises an open circuit of wiring connected to the terminal C and NO.
SCM-4 employs one red LED to indicate the status. In normal condition, the LED flashes. When the contact is activated, the LED will turn on constantly. In case of open circuit, the LED will turn off. Since the system allows maximum 13 LEDs on devices to turn on constantly, if system already has 13 lighted LEDs on devices, SCM-4 will not turn on the LED and keep
