Speaker Assembly

The bi-directional speaker must be assembled prior to installation. See Figure 3 on the back of this sheet for speaker assembly
information. Make sure to place the washer/seals where indicated and hand tighten the various components - do not use pliers
or similar tools.

Speaker Installation

STEP 1 - For easier installation, remove the flange (base) from the speak-
er by unscrewing the wing nut while at the same time pressing inwardly on
the wing nut. Place the flange flush with the mounting surface and mark the
location of the three holes with either a marker or chisel. It is important
that the three holes be exactly aligned with the flange, otherwise you might
stress the base or make the connection unsteady (see Figure 1). Insert 3
wall anchors - see diagrams on the back of this sheet for drilling instruc-
tions and use of anchors. (Use appropriate hardware for your specific
mounting surface.)
NOTE: Speaker may also be strap-mounted through the slot in flange (base)
using standard 1/2-inch industrial strapping (not included).
STEP 2 - After mounting the flange, reattach the speaker to the flange and
aim the speaker for the desired coverage. A 45
ommended, but this may vary depending upon speaker layout. Unless oth-
erwise indicated, do not aim speakers directly at each other or poor paging
intelligibility may occur.
STEP 3 - Remove the plastic cover to make the electrical connection and
set the tap set control (see Figure 2). Note: Use 22 AWG shielded, twisted
pair on all wire runs. Connect speaker wire shield to the ground (GND) ter-
minal of the amplifier's output. Carry the ground through all speaker cables
by tying the shields of the speaker cables together in a "daisy chain" fash-
ion. Do not connect the shield to the speaker itself. The shield is only
connected at the amplifier end and simply floats.
Connect wires as listed below:
Amplifier Outputs Speaker Connections
70V Terminal 1
COM Terminal 2
NOTE: The speaker will also work perfectly well with these connections reversed.
However, reduced low frequency response may result.
STEP 4 - Adjust the tap set control to the desired setting. See table at right
for tap settings and sound pressure levels for the different horn loudspeak-
ers. Replace the plastic protective cover back over the exposed area.
NOTE: The two furthermost clockwise settings on the volume control will
produce the same volume.
