NOHMI BOSAI FRRU004-MCM Miniature Contact Module

Manufacturer: NOHMI BOSAI
Model: FRRU004-MCM

Features of FRRU004-MCM

The FRRU004-MCM Miniature Contact Module is a compact device designed to monitor the contact status of an initiating device that contains a normally open or normally closed contact. This module plays a crucial role in fire alarm systems by supervising the contacts and reporting their status to the Fire Alarm Control Panel (FACP).
When the normally open contact is selected, and the contact closes, the FRRU004-MCM immediately sends a report to the FACP. Similarly, when a normally closed contact is used, and it opens, the module also updates the control panel.
This miniature contact module supervises an open circuit linked to the C and NO (NC) terminals. Its compact design makes it ideal for use in pull stations or other fire safety devices housed in electrical boxes or enclosures.
Additionally, the module features a UL-listed terminal block, ensuring that it meets safety standards by protecting against short circuits and ground faults. As a result, the FRRU004-MCM offers reliable performance in monitoring fire alarm systems.
