Nohmi FRRU004-SCM4 Single CONTACT Module
Single contact module (FRRU004-SCM4) is used to monitor the contact status of equipment containing normally open contacts (i.e. pull station, water flow switch, etc.) ,FRRU004-SCM4 can be programmed in the control panel to monitor normally open or normally closed contact on the Fire Alarm Control Panel (FACP) ,
When normally open contact is selected and contact closed, the FRRU004-SCM4 reports the condition of it tells FACP ,Likewise when the Normally Closed contact is set as a monitoring condition and the contact is opened, the FRRU004-SCM4 reports its condition to the FACP. The FRRU004-SCM4 monitors an open circuit of wiring connected to terminals C and NO. The FRRU004-SCM4 uses a red LED to indicate status. Under normal conditions, the LED flashes. When the contact is activated, the LED will turn on continuously. In the event of a problem, the LED will turn off.
