Standard Features:
Sirens are an integral part of an effective audio/visual emergency warning system. However, sirens are only short range secondary
warning devices. The use of a siren does not insure that all drivers can or will observe or react to an emergency warning signal,
particularly at long distances or when either vehicle is traveling at a high rate of speed. Sirens should only be used in a combination
with effective warning lights and never relied upon as a sole warning signal. Never take the right of way for granted. It is your responsibility to
be sure you can proceed safely before entering an intersection driving against traffic, or responding at a high rate of speed.
The effectiveness of this warning device is highly dependent upon correct mounting and wiring. Read and follow the manufacturer’s
instructions before installing this device. The vehicle operator should check the equipment daily to insure that all features of the device
operate correctly.
To be effective, sirens must produce high sound levels that potentially can inflict hearing damage. Installers should be warned to wear hearing
protection, clear bystanders from the area and not to operate the siren indoors during testing. Vehicle operators and occupants should assess
their exposure to siren noise and determine what steps, such as consultation with professionals or use of hearing protection should be
implemented to protect their hearing.
This equipment is intended for use by authorized personnel only. It is the user’s responsibility to understand and obey all laws regarding
emergency warning devices. The user should check all applicable city, state and federal laws and regulations. Code 3, Inc., assumes no
liability for any loss resulting from the use of this warning device.
Proper installation is vital to the performance of the siren and the safe operation of the emergency vehicle. It is important to recognize that
the operator of the emergency vehicle is under psychological and physiological stress caused by the emergency situation. The siren system
should be installed in such a manner as to: A) Not reduce the acoustical performance of the system, B) Limit as much as practical the noise
level in the passenger compartment of the vehicle, C) Place the controls within convenient reach of the operator so that he can operate the
system without losing eye contact with the roadway.
Emergency warning devices often require high electrical voltages and/or currents. Properly protect and use caution around live electrical
connections. Grounding or shorting of electrical connections can cause high current arcing, which can cause personal injury and/or severe
vehicle damage, including fire.
PROPER INSTALLATION COMBINED WITH OPERATOR TRAINING IN THE PROPER USE OF EMERGENCY WARNING DEVICES IS ESSENTIAL
TO INSURE THE SAFETY OF EMERGENCY PERSONNEL AND THE PUBLIC.

Automatic Short Circuit Protection - The siren will sense a short circuit on the speaker terminals and automatically go to standby until the
fault is removed. Once the fault is removed the siren will return to normal operation.
Hit-n-Go Mode - Setting the slide switch (DETAIL B, 4) inside, on the V-CON amplifier board toward the front panel will put the siren in the
Hit-n-Go mode. This mode will be most familiar to existing V-CON users. A seven second override is standard for all tones when activated
by the Manual button or the Remote input.See OPERATION section for details.
Siren Tones - Industry standard Wail, Yelp, and Hi-Lo tones.
AIR HORN Tone - Electronic AIR HORN sound.
Public Address - Public Address override of all siren functions when the microphone Push-to-Talk key is pressed.
Auxiliary Switch, Status LED - An indicator LED, visible on the front panel that informs the operator of the status of the A,B,C & D Auxiliary
switches (LED on indicates a switch is on).
Radio Rebroadcast - Broadcast Two-way radio reception over siren speakers. These inputs are transformer coupled to prevent loading of
the radio.
Remote Siren Switching – The siren can be connected to the vehicle’s horn switch (or other user supplied switch) and remotely activates
either the MANUAL or AIR HORN function (if equipped). Selection is made via the front panel slide switch. The siren is factory set as a Tri-
State input and will accept a positive (+12V) signal or a ground (earth) signal, but may be reconfigured to accept a positive only signal or a
ground only signal. See SET-UP AND ADJUSTMENT section for details.
Tone Priority/Manual Wail - The following tones are produced while pushing the MANUAL Push-button or triggering the user-supplied
REMOTE siren switch:
Manual Wail when the MANUAL Push-button is depressed while the rotary switch is in the STANDBY position.
