a. Connect the audio common leads (-) to the speaker’s
common terminal (marked COM). Refer to figures 2
and 3.
b. Connect the audio positive (+) leads to the + (SIG)
terminal.
c. Carefully reinstall housing cover using eight 5/16-18
x 1-3/4" hex head bolts, lockwashers and hex nuts
that were previously removed. Verify that all housing
and mounting bolts have been securely tightened.
WARNING
Property damage, serious injury, or death could occur if the
housing is not closed properly. To reduce possibility of
explosion, housing cover must be kept tight (all eight
bolts fully tightened) while circuits are energized.
WARNING
Audio wires should be sized properly by your licensed
installation electrician for your service application. This cable
requires a twisted shielded pair with an 18AWG mimum and
should produce no more than 15% signal loss over the
length of the cable run.
D.Testing/Operating.
WARNING
Under certain conditions these devices are capable of
producing sounds loud enough to cause hearing damage.
Adequate hearing protection should be worn if standing
within close proximity to device while testing. Recommenda-
tions in the OSHA Sound Level Standard
(29 CFR 1910) should not be exceeded.
1. After installation is complete, be sure to test the system
to verify that each speaker operates satisfactorily. If it
is found that the unit is too loud for its location, a
lower wattage tap may be selected. Carefully remove
the housing cover and move the speaker internal green
or red lead to a lower wattage tap (see figure 3).
Reinstall the housing cover and retest.
WARNING
Property damage, serious injury, or death could occur if the
housing is not closed properly. To reduce possibility of
explosion, housing cover must be kept tight (all eight bolts
fully tightened) while circuits are energized.
2.After completion of initial system test, establish a
program for periodic testing of this device. Refer to the
authority having jurisdiction for this information.
3.Provide a copy of these instructions for the Safety
Engineer, system operator(s) and maintenance person-
nel.
