Safety Message To Maintenance Personnel - Federal Signal AM302 Manual De Instalación Y Mantenimiento

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 minimum and
should produce no more than 15% signal loss over the length
of the cable run.
National Electrical Code as well as local codes must
be adhered to in installation of these models. All
electrical wiring must be routed through approved
conduit and fittings.
1. See figures 2 and 3. Connect the audio common (-)
leads to the speaker's common terminal.
2. Refer to figures 2 and 3. Connect the audio positive
(+) leads to the 25V or 70V terminal, depending on the
external signal source voltage.
3. Create a 4-inch long jumper using 14 - 22 AWG wire.
Connect one end of the jumper wire to the terminal
marked with the desired wattage (see figure 3). Connect
the other end to the terminal marked "SPK".
Only three (3) of the five (5) wattage terminals marked on the
terminal block are for use on the AM302 and AM302GCX.
For proper operation, the speaker wire should be connected to
one (1) of these terminals as indicated in figure 3. The remaining
two (2) wattage terminals are not used.
4. Be sure the neoprene rubber cover gasket is properly
seated in the housing groove and reinstall the housing
cover.

Property damage, serious injury or death could occur if the
housing is not closed properly. To reduce the possibility of
explosion, the Model AM302GCX's housing cover must be kept
tight while circuits are energized.
IV. TESTING/OPERATING.
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. Recommendations in the OSHA Sound Level
Standard (29 CFR 1910) should not be exceeded.
A. 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 yellow lead to a lower wattage
tap (see Figure 3). Reinstall the housing cover and retest.
Property damage, serious injury or death could occur if the
housing is not closed properly. To reduce the possibility
of explosion, the Model AM302GCX's housing cover
must be kept tight while circuits are energized.
B. After completion of initial system test, establish a program
for periodic testing of this device. Refer to the authority
having jurisdiction for this information.
C. Provide a copy of these instructions for the Safety Engineer,
system operator(s) and maintenance personnel.
SAFETY MESSAGE TO OPERATORS
Even if your warning system is operating properly, it may not
be completely effective. People may not hear or heed your
warning signal. You must recognize this fact and ensure that
your warning signal achieves its intended effect through proper
test/training sequences within your specific application(s).
V. MAINTENANCE.

SAFETY MESSAGE TO MAINTENANCE PERSONNEL

Failure to follow all safety precautions and instructions may
result in property damage, serious injury, or death to you or
others.
• Read and understand all instructions before performing
maintenance on this unit.
• To reduce the risk of electrical shock, or ignition of hazardous
atmospheres, do not perform maintenance or service on this
unit when circuits are energized.
• Periodic checks should be made to ensure that effectiveness
of this device has not been reduced because speaker has
become clogged with a foreign substance or because objects
have been placed in front of the speaker.
• Any maintenance to this unit MUST be performed by a trained
electrician in accordance with NEC guidelines and local
codes.
