Integrated Area Monitor
  • Long-life semiconductor sensor
  • Integrated visual and audible alarms
  • Affordable detection of VRF/VRV refrigerants
  • Remote sensor with aesthetic faceplate for discreet monitoring
  • Two on-board relays activate shut-off valves or fans


The IAM-100 area monitor is specifically designed to provide continuous monitoring of individual rooms in hotels, dormitories, hospitals and apartment buildings where a VRF/VRV or multi-split system is used as the air conditioning system. A refrigerant leak in such an installation could easily flood a room with a high concentration of refrigerant causing oxygen depletion at the floor level. For a less intrusive installation, the sensor can be remotely mounted from the main monitor.

If a pre-set alarm threshold is exceeded in an area, the IAM-100’s integrated audible and visual alarms are activated to alert occupants of the hazard. The two on-board relays can shut-off refrigerant supply lines, activate exhaust fans, or notify a building BMS or BAS systems. The IAM-100 can function as a standalone monitor or up to 16 units can be connected to an IAM Controller, which in turn can build a pyramid type monitoring system.
