WARNING! Sirens produce loud sounds that may damage hearing.
· Wear hearing protection when testing · Use siren only for emergency response
· Roll up windows when siren is operating · Avoid exposure to the siren sound
outside of vehicle
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”,
“HyperYelp”, 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.
Temp. Range:
-40ºC – 65ºC -40ºF – 149ºF

Low Frequency Configuration
Low Frequency Tone – The Low Frequency feature will only operate when the
primary siren system is generating a tone. When there is a signal from a
primary siren and the Low Frequency input is activated, the Low Frequency
Siren can generate one of three Low Frequency tones. The Low Frequency input
can be activated with a momentary switch and the Low Frequency Siren will
generate the Low Frequency tone for 7.5 to 60 seconds based on the Time-Out
configuration settings (see Low Frequency Time-Out).
The available tones are: · Divide main amplifier signal by 4 (1/4 Octave) ·
Divide main amplifier signal by 2 (1/2 Octave) · Divide main amplifier signal
by 4 & 2 (1/4 & 1/2 Octave)
To configure the Low Frequency Tone, set the DIP switches according to Table
- Low Frequency Time-Out – A momentary switch, such as the vehicle horn ring,
can be used to activate the Low Frequency tone. The Low Frequency Time-Out can
be configured to operate from 7.5 to 60 seconds. If the Low Frequency input is
activated by a toggle On/Off switch the Time-Out feature will shut off the Low
Frequency tone after the configured time has expired. The Low Frequency input
will have to be turned off before it can be activated again.
To configure the Low Frequency Time-Out set the DIP switches according to Table 1.

Installation and Mounting
The Low Frequency Amplifier may be mounted in the trunk or a console near the
primary siren. There are four mounting slots on the Low Frequency Amplifier.
All connections are made on one side of the siren. Mount the siren to allow
for easy access to this side. All connections are made to the quick disconnect
harness. See wiring diagram on page 9 for details.
Note: The safety of the vehicle occupants as well as the ease of operation and
convenience to the operator should be the prime consideration when mounting
the siren and controls.
All devices should be mounted in accordance with the manufacturer’s
instructions and securely fastened to vehicle elements of sufficient strength
to withstand the forces applied to the device. Ease of operation and
convenience to the operator should be the prime consideration when mounting
the siren and controls. Adjust the mounting angle to allow maximum operator
visibility. Do not mount the Control Head Module in a location that will
obstruct the drivers view. Mount the microphone clip in a convenient location
to allow the operator easy access. Devices should be mounted only in locations
that conform to their SAE identification code as described in SAE Standard
J1849. For example, electronics designed for interior mounting should not be
placed underhood, etc. Controls should be placed within convenient reach of
the driver or if intended for two person operation the driver and/or
passenger. In some vehicles, multiple control switches and/or using methods
such as “horn ring transfer” which utilizes the vehicle horn switch to toggle
between siren tones may be necessary for convenient operation from two
positions.
Convenient reach is defined as the ability of the operator of the siren system to manipulate the controls from their normal driving/riding position without excessive movement away from the seat back or loss of eye contact with the roadway.
Notes: 1. Larger wires and tight connections will provide longer service life
for components. For high current wires it is highly recommended
that terminal blocks or soldered connections be used with shrink tubing to
protect the connections. Do not use insulation displacement connectors (e.g.,
3M Scotchlock type connectors). 2. Route wiring using grommets and sealant
when passing through compartment walls. Minimize the number of splices to
reduce voltage drop. All wiring should conform to the minimum wire size and
other recommendations of the manufacturer and be protected from moving parts
and hot surfaces. Looms, grommets, cable ties, and similar installation
hardware should be used to anchor and protect all wiring. 3. Fuses or circuit
breakers should be located as close to the power takeoff points as possible
and properly sized to protect the wiring and devices. 4. Particular attention
should be paid to the location and method of making electrical connections and
splices to protect these points from corrosion and loss of conductivity. 5.
Ground termination should only be made to substantial chassis components,
preferably directly to the vehicle battery. 6. Circuit breakers are very
sensitive to high temperatures and will “false trip” when mounted in hot
environments or operated close to their capacity.
The user should install a fuse sized to approximately 125% of the maximum Amp
capacity in the supply line and each switched circuit to protect against short
circuits. For example, a 30 Amp fuse should carry a maximum of 24 Amps. DO NOT
USE 1/4″ DIAMETER GLASS FUSES AS THEY ARE NOT SUITABLE FOR CONTINUOUS DUTY IN
SIZES ABOVE 15 AMPS. Fuses or circuit breakers should be located as close to
the power takeoff points as possible and properly sized to protect the wiring
and devices.
