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.

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.
D. TESTING/OPERATING.
WARNING
Under certain conditions these devices are capable of pro-
ducing sounds loud enough to
cause hearing damage.
Adequate hearing protection should be worn if standing within
close proximity to device while testing. Recommendations 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 positive (+) 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 NFPA 72, local Fire Codes and
the authority having jurisdiction for this information.
3. Provide a copy of these instructions for the Safety Engineer,
system operator(s) and maintenance personnel.
