Alarm relay connectionsFigure 4-3:
1. To remove the cover, grab it by the upper edges and pull straight out. The relay
terminal strip is at the top of the board.
2.
Bring the relay wires through the rear conduit opening on the left hand side of the
enclosure and make connections to the terminals strip.
3. Replace the cover. The two tabs on the back edge of the cover fit into slots at the
rear of the enclosure, and the three small slots in the front of the cover snap into the
three tabs next to the relay terminal strip. See Figure 4-3. Once the tabs are lined up,
push the cover to snap it in place.
Keep alarm relay wiring separate from signal wiring. Do not run signal and power or relay
wiring in the same conduit or close together in a cable tray.
