RSM-CIM Hochiki FIREwave Wireless to Conventional Interface Module (RSM-CIM)


RSM-CIM Hochiki FIREwave Wireless to Conventional Interface Module

The Hochiki Wireless Conventional Interface Module (RSM-CIM) is a device that interfaces wireless field devices on to a Conventional Fire Control Panel (FCP) via the radial Zone circuit (for Detectors, Manual Call Points and Input Modules) and one of the radial Sounder circuits (for all Audio-Visual devices).

The RSM-CIM is powered from an external 24 V dc supply. Full monitoring and control of the wireless field devices is possible. Communication between the RSM-CIM, additional Expander Modules (RSM-EXP) (if fitted) and field devices is wireless via a bi-directional, analogue-intelligent protocol.


  • Bi-directional wireless communication.
  • Self optimising wireless amplitude and frequency.
  • Automatic wireless channel hopping.
  • Fully intelligent.
  • High reliability and sensitivity.
  • Flexible on site device adjustment.
  • IP68 protection for exterior mounting.
  • Makes additions to existing wired systems easy and cost effective.
  • Requires external power supply for use as stand-alone zone.
