About this detail

The signaling line circuit communication loop connects from the fire alarm control panel to the detector terminals with positive and negative polarities. A field installed jumper connects terminal 4 to terminal 2 on the RTS-451KEY remote test station. Wiring runs between the test station terminals 1 through 6 and the corresponding screw terminals on the first detector in the loop for test, LED, reset, common, and communication functions.
