the location of the alarm. The distance in meters is then
displayed on the 3½ digit LCD. Providing detection and
location along the complete length of the LHD cable.
With the ability to monitor up to 2000m for both Fire and
Fault conditions the DLI enhances any fire detection
capability and allows an appropriate action to be taken.
The DLI offers flexible interfacing 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
representing 0m to 2000m.
The DLI is available as a DIN Rail mountable unit or fitted
into an IP 65 weather proof enclosure.
