Nohmi FRRU004-MCM MINIATURE monitoring module
Miniature Contact Module (FRRU004-MCM) is used to monitor the contact status of initiating device containing normally open contacts ,FRRU004-MCM can be programmed in the control panel to monitor ,Normal Open or Normally Closed contact on the Fire Alarm Control Panel (FACP),
When the Normally Open contact is selected and the contact is closed, the FRRU004-MCM will report its condition to the FACP. Similarly when the Normally Closed contact is set to the monitor condition and the contact is opened, the FRRU004-MCM will report its condition to the FACP. The FRRU004-MCM monitors an open circuit of wiring connected to terminal C and contact NO (NC). The FRRU004-MCM is commonly used to monitor traction stations and other equipment where the module is installed in an electrical box or enclosure. The contact uses a shielded terminal block in accordance with UL requirements to protect against accidental failure and ground fault.
