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.
