Coverage

The distance you can be away from a speaker and still

have good talkback depends on the type of speaker

and ambient noise level.

The speaker should be as close as possible to the area

where talkback is desired. It should not be mounted

close to, or pointed at, noise producing equipment

such as fans, air conditioners, machinery, or

compressors.

The chart below shows maximum talkback distances

relative to the noise level of the surroundings.

Remember: The speaker is no better than

your ears. If you can not carry on a

conversation at normal voice levels over the

required talkback distance, then talkback

page equipment will not function

satisfactorily.

INSTALLATION

Cabling

Connections should be accomplished using regular

twisted pair wiring. Do not split pairs.

Connections

Connect station or other suitable wire to leads as

follows:

Attaching Speaker to Base

NOTE: For ease of installation, the base can be

attached to the speaker before or after the base is

mounted.

• Loosen position adjustment knob

• Insert the ball of the base into the socket of the

speaker

• Tighten the position adjustment knob

Mounting

Mount the horn to a suitable surface using the

hardware provided. These units can be mounted to a

wall, a beam, or an electrical box.

• Mount the base to a wall using the two holes

provided. Knockout holes are provided for

punch out should additional holes be desired.

• A "C" clamp is provided with the horns to allow

mounting to a beam. Place the bolt through the

hole in the bottom of the base to secure the "C"

clamp to the beam (See Figure 1). It is suggested

that the horn be mounted to the underside of the

"I" beam to provide maximum positioning

adjustments.

• Connection to an electrical backbox is

accomplished by channeling wire through the

ball of the base and making appropriate

connections. The base has holes punched for a

double-gang square box, but by punching out

additional knockout holes, the base can be

mounted to a single-gang or octagon box

(See Figure 2).

The horns may be rotated or moved up and down to

obtain the desired position by loosening the knob at

the bottom of the unit approximately one turn

(See Figures 1 & 2). Make required adjustments and

re-tighten knob.
