I. GENERAL.

These four SelecTone® Models are high output, continuous duty, indoor/outdoor
rated audible signal/amplified speaker devices with internal gain controls. A plug‑in
tone module is required for tone generation. If the use of externally generated tones or
voice signals from a remote amplifier is desired, the plug‑in speaker connector cards
may be used. See the specification section for compatible plug‑in models. These models
may also be used for playback of pre‑recorded messages or tones when used with the
Model TM‑33 Custom Tone Module. The mounting bracket is adjustable to allow posi‑
tioning to obtain desired sound coverage. Speaker projectors on all models are adjust‑
able and may be repositioned to obtain desired sound distribution.

The SelecTone Models 300GCX and 302GCX are designed for use in areas where
Flammable Gases, Vapors and Liquids and Combustible Dusts are not normally pres‑
ent, except for abnormal conditions as defined by the National Electrical Code. These
models are suitable for use in Class I, Division 2, Groups A, B, C, & D; Class II, Division
2, Groups F and G; Class III or non‑hazardous locations only. Reference the product
nameplate for additional information.

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.

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 connect the line (hot) power source wire to the terminal marked “L”. Con‑
nect the common (neutral) power source wire to the terminal marked “N”. See figure

2. If required by local building codes, connect the earth ground wire to the green screw
threaded into the interior of the housing.

b. 120VAC & 240VAC models.

Connect the line (hot) power source wire to the terminal marked
“L”. Connect the common (neutral) power source wire to the terminal marked “N”. See
figure 2. If required by local building codes, connect the earth ground wire to the green
screw threaded into the interior of the housing.
