The UL approved ProReact Digital Interface Monitor Module was designed to provide additional functionality when used in conjunction with ProReact Digital, ProReact Plus Digital or ProReact VHT LHD cable. It is an optional accessory but is highly recommended given the benefits it delivers to clients.
The ProReact Digital Interface Monitor Module can monitor up to 6,000 metres of digital linear heat detection cable across two zones and contains an in-built display showing the state of each zone, including the distance in metres and feet to the alarm point if an alarm is triggered. It also includes an RS-485 Modbus RTU output for integration with a PLC or SCADA system.
An optional unique interlock/coincidence detection mode eliminates the possibility of false alarms by requiring both zones of detection cable to trigger before an alarm is transmitted.
