d. Route wires through the 1/2" threaded openings into the SelecTone unit
in accordance with National and Local Electrical codes. Wire size depends
upon the operating current and the distance from the power source.
e. Select the mounting location and place rear of housing against mounting
surface.
f. Using the two (2) mounting holes as a template, scribe drill position
` marks on the mounting surface. See Figure 1 for mounting hole locations
and dimensions.
Before drilling holes in any surface, ensure that both sides of surface are clear
of items that could be damaged.
g. Secure the unit to a wooden mounting surface with #10 x 1" wood
screws. If mounting on a metal surface, drill 13/64" diameter holes and secure
the unit with #10 screws, lockwashers and nuts.
h. Reposition speaker projector if necessary to obtain desired sound cover‑
age. Loosen collar nut (see Figure 1) and move projector to desired position.
Install 1/2" conduit plugs in the unused bottom entryways (one plug supplied).
C. Electrical Connections
To avoid electrical shock, do not connect wires when circuits are energized.
Never energize unit unless the cover is securely fastened to housing. Property
damage, serious injury, or death could occur if the housing is not closed properly.
National and Local Electrical Codes must be adhered to in the installation and opera‑
tion of these models. All electrical wiring must be routed through approved conduit and
fittings as specified.
1. Power Connections
Use only 12 to 18 AWG [2.5 – 1.0 mm2] wire for the power connection. Strip
no more than .25 inch [6 mm] of wire insulation from the ends of the power leads. If
stranded wire is used, be sure that there are no loose strands outside the connector
plug that could touch the adjacent lead and cause a short circuit. Tighten terminal
screw 5 in‑lb (0.56 N‑m).
a. 24V AC/DC models
For 24VDC operation, connect the power source positive (+) lead to one of the (+)
terminals of the connector plug and connect the power source negative (‑) lead to one of
the (‑) terminals of the connector plug as shown in Figure 2. For 24VAC operation con‑
