C.ElectricalConnections.

WARNING

To avoid electrical shock, do not connect wires when 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 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".

NOTE

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.

WARNING

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.

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. 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.

WARNING

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).
