Conventional Products—B110LP Plug-In Conventional Low Profile Detector Base 9
The IDC zone wiring of the detector base should be checked before the
detector heads are installed in them. To make this possible, this base
contains a special spring-type shorting jumper. After a detector base is
properly wired and mounted on an electrical box, make sure that the
jumper spring is in contact with the base of Terminal 3. This temporary
connection shorts the negative-in and negative-out leads and permits the
wiring of the IDC to be checked for continuity.
Once all the detector bases have been wired and mounted and the IDC
wiring has been checked, the detector heads may be installed in the bases.
The shorting spring in the base will disengage when the detector head is
turned into place.
