e-Q2B Siren System

CHAPTER 4
Setting the Gain for Radio Rebroadcast and PA
The radio rebroadcast feature allows incoming two-way radio messages to be amplified by the siren
amplifier and rebroadcast over the siren speakers of the e-Q2B System. The Radio Rebroadcast function
is only available when the siren is in
MANUAL
Mode. The gain control for radio rebroadcast is a
potentiometer with a screw head on the front of the siren amplifier (Figure 4.2) on page 35.
For public address, the e-Q2B Siren System includes a microphone that connects to a serial port on the
front of the control head. When the operator presses the microphone push-to-talk button and speaks into
the microphone, the operator’s voice is amplified and broadcast over the siren speakers. The control for
adjusting the PA gain is a volume knob on the front of the control head (Figure 4.3 on page 35).
Setting the Gain for Radio Rebroadcast
To adjust the radio rebroadcast volume:
1.
Stand outside the vehicle in an inclosed area and turn on the two-way radio.
2.
Adjust the volume level of the radio to its normal operating volume.
3.
Set the dial on the control head to
MANUAL
(Figure 4.1)
4.
