Signaline HD+ Programmable Linear Heat Detection Controller (SL-HDP-CTL)

The Signaline HD+ Controller is the fully programmable control unit for the Signaline HD+ programmable linear heat detection system, manufactured in the UK by LGM Products and approved to EN 54-22 and UL 521. It continuously checks the HD+ sensor cable for temperature changes and lets the user set alarm and pre-alarm thresholds to suit the area, level of risk, approval standard and alarm temperature required. The system can be reset manually at the controller or automatically after a heat event, without replacing the detection cable.

Key features

• Programmable alarm and pre-alarm thresholds
• Resettable system: no need to replace the cable after an over-heat event
• Alarm and pre-alarm Form C relay outputs plus opto-isolated fault output
• 2-wire RS-485 Modbus output
• IP65, IK08 enclosure
• For use with Signaline HD+, HD+ R or HD+ S cable and the HD+ EOL unit
