The figure below is an example of a connection layout between the receiver and a hardwired anti-
intrusion control panel with 8 intrusion zones and a technical input.
In this example, the technical input is wired to the receiver’s “fault” output so that the hardwired
system can supervise fault signalling.

3.2 Connection example
IMPORTANT: ensure polarities are properly connected for TMP and FLT inputs.
(1) ITR = Intrusion input end-of-line resistance.
(2) TTR = Technical input end-of-line resistance. In the example, the technical zone is used to supervise
system radio peripheral faults.
(3) The “installation connected” input/output is the status (armed/disarmed) of the hardwired control
panel.
