B. Mechanical Installation.
The 300 SelecTone can be mounted on any flat surface. After the mounting location and mount-
ing method have been selected, proceed with the instructions below. When installing the Selec-
Tone, seal all holes and conduit fitting threads that pass through the housing with Teflon tape or
other sealing material.
1. Loosen the two screws that secure the cover to the housing. Gently pull the cover away from
the housing.
2. Place the rear of the selectone housing against the mounting surface. Use the two mounting
holes at the rear of the housing as template, and scribe positioning marks on the mounting
surface.
Before drilling holes in any surface, ensure both sides of the surface are clear of
3. Secure the unit to wood, plastic, etc. with #10 x 1-inch wood screws. When installing the
unit on metal surfaces, drill 13/64-inch diameter holes at the positioning marks and secure
with #10 bolts, lockwashers and nuts.
C. Connection to Power Source.
To avoid electrical shock, do not connect wires with power applied.
Use only 12 to 18 AWG wire for power connection. Strip no more than 0.25-inch of wire
insulation from the ends of the power leads. Connect 250VDC power leads to the 250VDC
terminals of the four position plug-in connector at the receptacle TB1. Connect positive lead to
the (+) terminal and negative lead to the (-) terminal of the four position plug-in connector as
shown in figure 1, by inserting the stripped ends of the wires in to the connector as far as they
can travel. Make sure the supply lead insulation is flush with the connector. If stranded wire is
used, be sure that there are no loose strands outside the connector plug that could touch the ad-
jacent lead and cause a short circuit. Install the plug-in tone module. Replace the cover on the
housing using the screws that were removed in step B.1.
D. Speaker Positioning.
Property damage, serious injury or death could occur if the speaker projector is mishandled
during installation or over time. DO NOT rotate the projector more than 180 degrees
The SelecTone 300 is constructed to allow 180 degrees speaker rotation, when required.
To rotate the speaker, loosen the steel collar nut which secures the speaker to the housing. Ro-
tate the speaker to the desired position. Tighten the collar nut.
IV. OPERATION.
Listed below are some important safety instructions you should follow:
• Read and understand all instructions before operating this unit.
• All effective warning speakers produce loud sounds which may cause, in certain situations, per-
manent hearing loss. You should take appropriate precautions such as ensuring that the recom-
mendations in OSHA Sound Level Standard (29CFR 1910) 1910.95 are not exceeded.
• Although your warning system is operating properly, it may not be completely effective. People
may not hear or heed your warning signal. You must recognize this fact and ensure that your
warning signal is achieving the desired effect.
The 300 SelecTone (250VDC) is activated by turning ON a user supplied switch, that applies
250VDC to the unit. Activate the unit only after moving away from the speaker.
