Signaline LocatorPlus-EN Linear Heat Detector Controller (SLP-002)

The Signaline LocatorPlus-EN (SLP-002) is a dual zone monitor module for Signaline FT-EN linear heat detection cables, approved to EN 54-28. Each zone can monitor up to 1,000 m of cable, and in the event of an alarm the unit immediately displays the alarm location and zone of the activation. Used with Signaline FT-EN cable and the FT-EOL-EN end-of-line unit, it forms a complete EN 54-28 approved system. It needs no specialist software or programming tools.
