MANUAL Pushbutton Momentary Switch - Produces the Manual tone as described above.
AIR HORN Pushbutton Momentary Switch- Produces the Air Horn tone as described above.
SLIDE SWITCH - The slide switch located on the front of the siren amplifier selects the function for the
REMOTE (external switch) circuitry. When the siren is in standby mode and switch is to the right, the Horn
Ring circuitry remotely "depresses" the AIR HORN button and it produces the effects outlined above. When
the slide switch is to the left, it allows the REMOTE circuitry to remotely "depress" the MANUAL pushbutton.
This causes the effects described above to occur.
Switch Operation - Scroll Mode Selected
The " Scroll " mode is designed to allow the user to scroll through Wail, Yelp, HyperYelp and Airhorn tones by
utilizing the Remote input on the siren. This will usually be connected to the vehicle Horn Ring circuit. When the
three level lighting control switch is in postition 2 or 3, the Horn Ring transfer relay is energized. The user can
use the Horn Ring to sequence through Wail,Hyperyelp and Yelp by applying a quick, sharp tap on the horn.
Additional taps will scroll the siren to the next tone. Depressing the horn for longer periods will produce "
Airhorn".
Function Selection
RRB - In the ON position, the audio from the 2-way radio is rebroadcast over the siren speaker. Note, the
siren is not disabled in this mode. The siren will generate siren tones if selected then revert to RRB mode.
STANDBY - This is the standby mode, when the MANUAL button is depressed the Manual wail tone will
ramp up until it reaches a peak then ramp down when released. If the AIR HORN button is depressed, the
Air Horn sound will be produced.
WAIL - This mode produces the Wail tone. Depressing the MANUAL button will now produce Manual wail
tone and ramp up until released. Depressing the AIR HORN button will produce the Air Horn sound. The
siren can be scrolled in this position as described above. The Remote/Horn Ring input will also activate the
Interclear output for 7 seconds.
YELP - This mode produces the Yelp tone. Pushing the MANUAL button will now produce the Manual wail
tone and ramp up until released. If the AIRHORN button is pushed, the Airhorn sound will be produced. The
siren can be scrolled from this position as described above. The Remote/Horn Ring input will also activate
the Interclear output for 7 seconds.
HI-LO - This position produces the Hi-Lo tone. Pushing the MANUAL button will produce the Manual Wail
tone until released. If the AIRHORN button is pushed, the Airhorn sound will be produced and when
released the siren return to Hi-Lo.The siren cannot be scrolled from this position. The Remote/Horn Ring
input will activate the Interclear output and cause the tone to change to HyperLo for 7 seconds.
Push-to-Talk (PTT) Microphone Switch - Keying the microphone will automatically override whatever
mode the siren is in and broadcast public address messages over the siren speaker.
MANUAL Pushbutton Momentary Switch - Produces the Manual tone as described above.
AIR HORN Pushbutton Momentary Switch - Produces the Air Horn tone as described above.
MANUAL / AIRHORN SWITCH - The MANUAL / AIRHORN slide switch located on the front of the siren
amplifier, Figure 5, selects the function for the REMOTE (external switch) circuitry when the siren is in standby
mode. When the the siren is in standby mode and switch is to the right, the Horn Ring circuitry remotely
"depresses" the AIR HORN button and it produces the effects outlined above. When the slide switch is to the
left, it allows the REMOTE circuitry to remotely "depress" the MANUAL pushbutton. This causes the effects
described above to occur. When in the "Scroll " mode this switch has no effect unless in STANDBY
position.
