FirePlus-LHD Digital Interface Unit, LHD-DIU, UL Listed

The FirePlus-LHD Digital Interface Unit shows the exact location of a fire or overheat along the length of the Context Plus linear heat detection cable, so the response can be immediate.

It connects to Context Plus conventional and addressable panels, and to industrial process control systems through its RS485 Modbus RTU output.

Key features:

• Accurate location of the alarm point along the cable.
• Monitors up to two zones for fault or fire.
• Zones operate independently or in interlock (coincidence) mode, needing both cables to trigger before an alarm.
• Volt-free fire and fault outputs for each zone.
• Two-wire RS485 Modbus RTU output.
• Built-in sounder.
• UL 864 10th Edition approved, UL listed.

Typical applications:

• Long cable runs in tunnels, conveyors and cable trays where the fire location must be known.
