Installation Instructions:
Wiring methods shall be in accordance with the National Electrical Code/NFPA 70/NFPA 72/ANSI, and with
all local codes and authorities having jurisdiction. Product is intended for indoor use only.
1. Mount unit in the desired location. Mark and predrill holes in the wall to line up with the top two keyholes
in the enclosure. Install two upper fasteners and screws in the wall with the screw heads protruding. Place
the enclosure’s upper keyholes over the two upper screws, level and secure. Mark the position of the lower
two holes. Remove the enclosure. Drill the lower holes and install the three fasteners. Place the enclosure’s
upper keyholes over the two upper screws. Install the two lower screws and make sure to tighten all screws
(Enclosure Dimensions, pgs. 7, 8). Secure enclosure to earth ground.
2. Set power switch to OFF position on all models (Figs. 1 - 3, pgs. 4 - 6).
3. All units are factory set for 24VAC operation.
4. Secure green lead to earth ground. Connect AC power to the black and white flying leads of the
transformer(s)
(Figs. 1 - 3, pgs. 4 - 6). Use 18 AWG or larger for all power connections.
Keep power-limited wiring (PTC protected outputs only) separate from non power-limited wiring.
Minimum 0.25” spacing must be provided. Use separate knockouts
5. Measure output voltage before connecting devices. This helps avoiding potential damage.
Terminals marked [1A - 8A] and [1B - 8B] are of the same polarity (phase).
6. Connect CCTV cameras to output terminals using the following procedure:
Camera 1 to output 1A & 1B.
Camera 5 to output 5A & 5B.
Camera 2 to output 2A & 2B.
Camera 6 to output 6A & 6B.
Camera 3 to output 3A & 3B.
Camera 7 to output 7A & 7B.
Camera 4 to output 4A & 4B.
Camera 8 to output 8A & 8B.
7. Set power switch on all models to the “RESET” (ON) position (Figs. 1 - 3, pgs. 4 - 6).
8. Upon completion of the wiring, secure enclosure door with screws (supplied).
