Speaker Installation

Horn speakers produce high sound levels and are capable of covering large,noisy areas.Minimum effective mounting height for

a horn is 15 feet;20 feet is preferable.However,in a system with talk-back (hands-free answer back),the speaker may have to

be mounted as low as 8 to 12 feet and set at a lower power setting.

CAUTION: Do not connect more than two (2) speakers per talk-back zone.

Speakers must be mounted in locations that provide a clear sound path to the area paged. Avoid placing speakers in front of

shelves,partitions,or other obstructions.To avoid feedback,do not place telephones near speaker installation.

CAUTION: The 1-Watt Tapped Horn Loudspeaker is not compatible with any 70- or 25-volt line audio distribution products.

Various power outputs can be easily selected on the speakers using the rotary power switch.

Mounting

1.Loosen the wing nut and remove the tapered locking pin. A light tap on the end of the pin may be required to free it.

2.Mount the bracket using appropriate hardware (not supplied).It can be mounted either to a pole using a band slot or to a flat

surface using the 3 holes in its base (see Figure 1).

3.Position the horn for sound direction and hand tighten the wing nut. A 45

downward angle is recommended,but this may vary

depending upon speaker layout.Unless otherwise indicated,do not aim speakers directly at each other or poor paging

intelligibility may occur.

CAUTION: When positioning the speaker,the mounting bracket will bind if the wing nut and its tapered locking pin are not

sufficiently loosened.Forcing the horn will damage the mounting bracket.Be certain that the wing nut is loose and that the tapered

pin is free before trying to adjust the position of the horn.

4.Reattach the horn and the bracket by reversing the mounting procedure.
