Installation
The devices are attached to a suitable structure by use of the top anchor point. This allows for firm
connection without compromising the weatherproofing of the enclosure.
The LHD-INT unit has two cable glands, the left hand gland facilitates the entry of the digital linear
heat cable so that it can be terminated in the LHD-INT as shown in diagram 3. The right hand cable
gland allows for a 4 core cable to enter the LHD-INT unit to terminate the 24Vdc power and the
zone interface. The LHD-INT can be connected directly to a conventional fire panel zone and
auxiliary power output or to an input interface from an addressable fire detection panel.
The termination into the INT-EOL is simply one core of the digital linear heat cable into each
terminal, there is no need to observe any polarity.
PLEASE NOTE neither the LHD_INT OR LHD_EOL will operate correctly without both being
installed on the digital linear heat cable.

Fire and EOL resistors are dependent on the fire alarm control equipment specification.
