Zonecheck Addressable is a Zonecheck which is controlled and monitored via a central controller specifically designed by Project Fire. The Zonecheck unit (comprised of flow-switch, circulating pump and test line), is wired to an IMM (intelligent monitoring module) instead of the key-switch which can be found on non-addressable versions. The IMMs are linked to a Zonecheck Addressable Controller where all testing, monitoring and record keeping for flow-switch testing and more can be achieved from one central location.
