Code 3 V-Con Siren - Manual (Page 9)

9
"Wail" and "Yelp" tones are in some cases (such as in the state of California) the only recognized siren
tones for calling for the right of way. Ancillary tones such as "Air Horn", "Hi-Lo", "Hyperyelp", and "Hy-
perlo" in some cases do not provide as high a sound pressure level. It is recommended that these tones
beused in a secondary mode to alert motorists to the presence of an emergency vehicle.
Operation
Rotary Function Selector Switch
RADIO - In the RADIO position, the audio from the 2-way radio is rebroadcast over the siren speaker. The siren tones (Wail, Yelp, &
Hi-Lo) do not operate in this position.
STANDBY - This is the standby mode. If 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 position produces the Wail tone. Depressing the MANUAL button will now produce the Yelp tone for 7 seconds. De-
pressing the AIR HORN button will produce the Air Horn sound and when released will return siren to Wail tone.
YELP - This position produces the Yelp tone. Pushing the MANUAL button will continue to produce the Yelp tone. If the AIRHORN
button is pushed, the Airhorn sound will be produced and when released will return the siren to Yelp.
HI-LO - This position produces the Hi-Lo tone. Pushing the MANUAL button will now produce the Yelp tone for 7 seconds. If the
AIRHORN button is pushed, the Airhorn sound will be produced and when released will return siren to Hi-Lo.
P.A. VOLUME Knob - This control adjusts the level of the P.A. audio produced when keying the microphone and speaking into it.
This control also controls the Radio Re-broadcast level when in the " Radio " position (see SET-UP, Radio Rebroadcast Adjustment).
Push-to-Talk (PTT) Microphone Switch - Keying the microphone will automatically override whatever mode the siren is in and broad-
cast public address messages over the siren speaker. PTT operates in all positions of the Selector switch.
MANUAL Pushbutton Momentary Switch -Has no effect when the selector switch is in RADIO, produces the effects described above
for each selector position.
AIR HORN Pushbutton Momentary Switch (Models 3692, 3694, 3692L4 & 3694L4 only) - Produces the Air Horn tone in all selector
switch settings except RADIO.
SLIDE SWITCH (Models 3692, 3694, 3692L4 & 3694L4 only) - The slide switch located between the AIR HORN and MANUAL but-
tons selects the function for the REMOTE (external switch) circuitry. When the switch is to the right, the Horn Ring circuitry remotely
"depresses" the AIR HORN button and generate the
AIR HORN tone. When the slide switch is to the left, it
allows the REMOTE circuitry to remotely "depress" the MANUAL pushbutton and generate the
MANUAL tone.
