Record and Playback
Placing the 9005 compatible siren controller in the play mode allows up to 30 seconds of recorded
message to be broadcast over the sirens speaker on a continuous loop.
Pressing and holding the PTT button records from the microphone as long as the PTT is held
in.
To wipe the message quickly press and release the PTT button while the play mode is
selected.
Volume control
The volume for the audio functions (PA, Play, Radio rebroadcast) can be adjusted on some of the 9005
compatible siren controllers. This is either a volume knob on the controller or Volume plus and minus
buttons. Note the volume cannot be adjusted on the STC and MTC handsets and is pre-set to the
highest setting.
Radio Rebroadcast channel 1 –This input allows a signal in the range of 0.5Vp-p to 10Vp-p to broadcast
over the siren speaker, when selected by the controller.
The acceptance range for the channel 1 input can be adjusted using the man and horn buttons on the
8007 controller while radio channel 1 is selected.
First connect your audio device to the radio inputs 1a and 1b (polarity doesn’t matter) and
set the volume on the device to maximum.
Select radio 1 on the controller (by default the siren amplifier is set to the maximum input
voltage)
Turn the volume to maximum on the controller
Press and hold the horn button to decrease the input voltage setting, increasing the
preserved volume (a beep will be audible as the level changes).
Press and hold the man button to increase the input voltage setting, decreasing the
perceived volume (a beep will be audible as the level changes).
There are 9 volume pre-set levels that can be selected; the aim of pre-setting the volume is to achieve
a good volume without the siren amplifier cutting out, or the audio being rebroadcast being clipped.
The CP49 control panel can also adjust the volume pre-set levels for the radio rebroadcast, by holding
down the radio button and pressing the volume buttons to increase or decrease the preset level.
Radio Rebroadcast channel 2 –This input allows a signal in the range of 0.5Vp-p to 10Vp-p to broadcast
over the siren speaker.
The acceptance range for the channel 2 input can be adjusted using the man and horn buttons on the
8007 controller while radio channel 2 is selected, using the above method.
