Siren Set-Up and Adjustment

The only adjustments necessary for the siren are Maximum P.A. Adjustment (accessible from the outside of
the unit), and Maximum RRB Adjustment (accessible only with the cover removed).
Audio Adjustments
Maximum Radio Rebroadcast (RRB) Adjustment - This trimmer (under the siren cover) sets the maximum
level that the 2-way radio will reach with the front panel VOLUME control in the fully clockwise position. To
adjust properly, set the 2-way radio volume control to produce normal radio volume from the 2-way radio
speaker or headset. Set the RRB switch to the on position to enable the RRB function. Next set the siren's
front panel VOLUME control knob fully clockwise and adjust the rear panel RRB trimmer to produce the desired
volume from the siren speaker.
Maximum P.A. Volume Adjustment - This trimmer sets the maximum level that the P.A. volume will reach
with the front panel VOLUME control in the fully clockwise position. To adjust properly, set the front panel
volume control fully clockwise. While keying the microphone hold the microphone close to your lips and speak
directly into it in a normal voice and adjust the trimmer until the maximum volume out of the speaker is
intelligible and produces no feedback. Set the front panel volume control for the desired PA volume and install
all screws and fasteners. Jumper J1 allows the PA input sensitivity to be changed from "normal" microphone
level to "CHP radio compatible". See board layout on page 9. Default position is "normal" - move the jumper to
"CHP radio compatible" if you are using the PA output from the GE S890 radio.
HyperYelp Disable Switch - Switch is shown in the figure following. When switch 2 on DS1 is switched to the
ON position, the HyperYelp tone is disabled. Switch 1 is not used.

Siren Operation

SCROLL, Momentary Push-button Switch - Each time the SCROLL button is pressed it causes the siren to
scroll up one tone. Starting from the OFF mode, pressing the SCROLL button will cause the siren to start
producing the WAIL tone. Pressing the button again will cause the siren to switch to YELP mode. Pressing the
button again will cause the siren to switch to HyperYelp mode. Pressing the button a fourth time will cause the
siren to switch back to WAIL mode. This process may be repeated as often as desired.
WAIL, Latching Switch - Produces the Wail tone continuously while this switch is in the ON position.
AIR HORN, Momentary Push-button Switch - Produces the Air Horn tone. If the siren is active in any mode, it
reverts to that previous mode when the AIR HORN button is released.
RRB Switch - The RRB switch, is used to enable or disable the Radio Rebroadcast (RRB) function. When RRB
is enabled, all other siren functions except PA are disabled.
When the switch is on, the 2-way radio audio connected to the RRB input wires is routed through the siren
amplifier to the siren speaker. The RRB volume from the siren speaker may be set by adjusting the 2-way
radio's volume control. Also refer to Maximum Radio Rebroadcast (RRB) Adjustment under the SET-UP AND
ADJUSTMENT section.
PUBLIC ADDRESS (PA) - The PA portion of the siren is activated each time the motorcycle Push-to-Talk (PTT)
button is pressed while the user supplied common microphone interface is set to PA mode. While the PTT
button is pressed, the PA function overrides any active siren tone and routes the PA audio through the siren
speaker. When the PTT button is released, the siren will automatically switch back to the siren tone (if any)
that was active when the button was pressed. Also refer to the Maximum P.A. Volume Adjustment procedure
under the SET-UP AND ADJUSTMENT section.
INTERCLEAR - The InterClear output provides a timed output from the siren which can be used to activate a
special warning light or function. Each time the siren mode is changed by any of the means previously
described the InterClear output switches on (+12VDC, 1A Max) for approximately eight (8) seconds. Turning the
siren off will also turn the InterClear output off.
