Installation of STCH-1000LC:
Model STCH-1000LC is designed to be wall mounted. It has an attached 6-foot
line cord. Be sure that the outlet into which you plug the detector is not controlled
by a switch and that the detector is not obstructed by drapes etc.
Slide the mounting plate to the right to remove from the back of detector. Using
the enclosed screws and anchors install the mounting plate on the wall 5 to 6 feet
above the floor within cord reach of the outlet. Install the detector back on the
mounting plate and slide to the left to lock the detector in place.
Installation of STCH-1000HW:
STCH-1000HW has one set of AC power wire harness. For the AC Power Quick
Connector wiring connection, the black wire is connected to 120VAC Hot line, and
the white wire is connected to the Neutral line (see Figure 3A).
Installation of STCH-1000HWR:
STCH-1000HWR has two sets of wire harness, AC power and relay. For the AC
Power Quick Connector wiring connection, the black wire is connected to 120VAC
Hot line, and the white wire is connected to the Neutral line (see Figure 3A).
Installation of PSM-011:
PSM-011 has two sets of wire harness, DC power and relay. For the DC Power
Quick Connector wiring connection, the red wire is connected to 12VDC, and the
black wire is connected to 0VDC (see Figure 3B).
Connections on the relay:
