Module giám sát lối vào NOHMI FRRU004-MCM

– The Miniature Contact Module (FRRU004-MCM) is used to monitor the contact status of an initiating device that contains a normally open contact.

– The FRRU004-MCM can be programmed in the panel to supervise either a Normally-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 reports its condition to FACP. Likewise when the Normally-closed contact is set to a supervising condition, and the contact is opened, the FRRU004-MCM reports its condition to FACP. FRRU004-MCM supervises an open circuit of wiring connected to the terminal C and NO (NC) contact. The FRRU004-MCM is generally used to monitor pull stations and other devices where the module is installed in an electrical box or enclosure. The contact utilizes a terminal block that is covered in accordance with UL requirements to protect from inadvertent shorts and ground faults.

Features
