SD-2 DETECTOR TO REMOTE AREA DETECTOR
SD-2 DETECTOR TO AUDIBLE SIGNAL APPLIANCE
A remote open area detector can only be connected to a unit whose trouble relay contacts
(#5 & #13) are connected in a circuit for the purpose of obtaining an audible trouble signal
in the event of a circuit fault. In the event that the unit is used for releasing service only,
the trouble contacts are connected to the trouble circuit of a UL/ULC listed alarm control
panel. This condition is satisfied by the four (4) and six (6) wire supervisory connections in
the alarm initiation wiring section. Perform wiring connections as illustrated below. NOTE: The
SD-2 is wired as the E.O.L. (end of line) device for the remote detector. Therefore, it
must act as the last item in the loop.
