SET-UP AND ADJUSTMENT
Make these adjustments and position the set-up switches prior to final mounting.
Audio Adjustments
PA/RRB Volume Adjustment - This is the main volume control located on the right side of the front panel. This control
sets the PA and RRB volume. Set the front panel volume control to the point that the PA volume from the siren speaker is
such that there is no feedback and the PA audio is intelligible.
Radio Rebroadcast Adjustment - Place the selector switch in the RADIO position. The MAX RRB trimmer located on the
rear panel of the siren and is accessible through the small hole labeled RRB. This control sets the maximum RRB level
that will reach with the front panel volume control. To adjust properly, set the volume knob fully clockwise and adjust the
RRB trimmer such that with the two-way radio volume inside the vehicle set to it's normal level, the the desired volume
level is produced outside the vehicle by the siren speaker.
Remote Input
The Remote input can be configured to activate in one of three modes: 1) Tri-State Input - accepts
a positive (+12V) signal or a ground (earth) signal, 2) Positive Only Input – accepts only a positive
(+12V) signal or 3) Ground Only Input – accepts only a ground (earth) signal. All 3600 series sirens
are factory set as a Tri-State Input. To reconfigure the Remote input to accept a Positive Only Input,
power up the siren while pressing the MANUAL button and holding it for approximately three (3)
seconds. When the MANUAL button is released the siren will be reconfigured to accept a Positive
Only Signal. To reconfigure the Remote input to accept a Negative Only Input, power up the siren
while pressing the AIR HORN button and holding it for approximately three (3) seconds. When the
AIR HORN button is released the siren will be reconfigured to accept a Negative Only Signal. To
restore the Remote input to the factory setting, power up the siren while pressing the MANUAL and
AIR HORN buttons and holding them for approximately three (3) seconds. When the MANUAL and
AIR HORN buttons are released the siren will be restored to the factory setting (Tri-State Input).
NOTE: The siren will not generate the MANUAL or AIR HORN tones during the configuration pro-
cess.
