SIREN TESTING
Before re-connecting the battery in the vehicle make sure that the siren is turned off. Observe
polarity when re-connecting.
Caution: Hearing protection should always be used when testing any siren, especially
indoors. The sound levels produced by the speakers may cause hearing loss.
The following procedure should be used to test the siren:
1. With the function selector set to the HRN/T-T position and Dual switch off turn on the
power switch. Nothing should be heard from the speakers.
2. Press the Siren button. The speakers should emit a simulated Air-Horn sound while
the button is pressed. (If the auxiliary lead is used check the appropriate switch and/or
horn-ring operation. The result should be the same.)
3. Set function selector to PHASR/W-Y and turn on the Dual switch. You should hear
Wail out of one speaker and Yelp out of the other.
4. Test the microphone operation by pressing the microphone button and speaking. The
noise-canceling microphone should be held close to the lips for proper operation. Use
the volume control to adjust the sound level.
5. If the Radio input leads are connected test this function by setting the function switch to
this setting. Adjusting a control through a hole in the amplifier sets the sound level.
