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. Depressing 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.
IMPORTANT WARNINGS TO USERS OF SIRENS: “Wail” and “Yelp” tones are in some cases (such as the state of California) the only
recognized siren tones for calling for the right of way. Ancillary tones such as “Air Horn”, “Hi-Lo”, “Hyper-Yelp”, and “Hyper-Lo” in
some cases do not provide as high a sound pressure level. It is recommended that these tones be used in a secondary mode to alert
motorists to the presence of multiple emergency vehicles or to the momentary shift from the primary tone as an indication of the imminent
presence of any emergency vehicle.
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 broadcast
public address messages over the siren speaker. PTT operates in all positions of the Selector switch.
MANUAL Push-button Momentary Switch -Has no effect when the selector switch is in RADIO, produces the effects described above for
each selector position.
AIR HORN Push-button Momentary Switch (Models 3692 and 3692L4 only) - Produces the Air Horn tone in all selector switch settings
except RADIO.
Slide Switch (Models 3692 and 3692L4 only) - The slide switch located between the AIR HORN and MANUAL buttons 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.
Lighting Controls (For L4 Models Only):
Auxiliary Switch “A” - Supplies power to the load connected to terminal SW A.
Auxiliary Switch “B” - Supplies power to the load connected to terminal SW B.
Auxiliary Switch “C” - Operates circuit connected to terminals SWC NO, SWC NC, SWC COM.

Auxiliary Switch “D” - Supplies power to the load connected to terminal SW D.
SirenLock - The SirenLock option, when not defeated by means of the internal switches, allows siren tones (Wail, Yelp, and Hi-Lo) to be
produced only when the Warning Light Switch is in the Lighting Level 2 (Green and Yellow LED’s) or Lighting Level 3 (Green, Yellow, and
Red LED’s) position. Air Horn, Radio Rebroadcast, and Public Address are unaffected by this option.
