Linesense DLI-2K Digital Location Interface (Monitoring Distance 2Km)

DLI-2K Digital Location Interface (Monitoring Distance 2Km)

The Digital Location Interface (DLI) monitors the Linear Heat Detection cable and identifies the location of the active alarm. The distance is then displayed in meters on the 3½ digit LCD. 

The DLI is able to monitor up to 2000m for both Fire and Fault conditions. This enhances any fire detection capability and allows an appropriate action to be taken. 

The DLI also offers flexible interface options, designed as a two-wire device for connecting directly into a conventional fire alarm panel. It also has the ability to signal via volt free relay contacts for Fire and Fault, plus a 4-20 mA output. 

IP 65 weatherproof lockable Polycarbonate enclosure with M20 and M25 cable gland knockouts.
