1W Tapped Horn Loudspeaker

Description

PEC Code: 5331-001 COM Code: 408184109 Model: LU1WVCH

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 n ut. 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.

Wire Connections

The speaker has screw-type terminals,which are protected by a clear plastic cover. The cover also acts as a strain relief for the wires after they are connected. The procedure for connecting the speaker is given in the following steps:

1.Loosen the screws that hold the plastic cover and swing the cover out of the way.

2.Make the connections and dress the wire as shown in Figure 2.

3. When using shielded speaker wire, and wiring from speaker to speaker, wire the shield drains to provide a continuous shield to the next speaker. Otherwise, clip the shield wire at the point it emerges from the main cable. The shield wire should never be terminated on the speaker.

4.Do not replace the plastic cover until final power adjustments have been made.

Note: When connecting from speaker to speaker,the speaker must be kept in phase. This means that all number 1 (-) terminals must connect on the same wire, and all number 2 (+) terminals must be connected on the other wire.

Final Power Adjustments

1.Ensure that the speaker is set to its lowest setting (this will prevent an excessively loud page when first used).

2. While a page is in process, adjust the volume control with a screwdriver. Turn clockwise to increase the volume (see table below).

3.Install the plastic cover.
