SAFETY MESSAG E TO INS TALLERS O F

UNITROL SYSTEMS

WARNING

The lives of people depend on your safe installation and
servicing of UNITROL products. It is important to read
and follow all instructions shipped with the products. In
addition, listed below are some other important safety
instructions and precautions you should follow:

Before Installation

Qualifications

• To properly install an electronic siren you must have a

good understanding of automotive electrical
procedures and systems, along with proficiency in the
installation and service of safety warning equipment.

Sound Hazards

• Your hearing and the hearing of others, in or close to

your emergency vehicle, could be damaged by loud
sounds. This can occur from short exposures to
moderately loud sounds. For hearing conservation
guidance, refer to federal, state, or local
recommendations. OSHA Standard 1910.95 offers
guidance on “Permi ssible Noise Exposure.”

• All effective sirens and horns produce loud sounds,

which may, in certain situations, cause permanent
hearing loss. You should minimize your exposure
times and wear suitable hearing protection.

During Installation

• DO NOT connect this system to the vehicle battery

until ALL other electrical connections are made,
mounting of all components is complete, and you have
verified that no s horts exist.

• Be sure the siren amplifier and speaker(s) in your

installation have compatible wattage ratings.

• Wire size range from 10 ga (largest) to 20 ga.

(smallest). Do not use wire that is smaller than any
vehicle wire being cut apart. Always use a size that
can safely carry the load to be operated.

• If Slide Switch outputs may possibly exceed 20

amps per position, utilize a circuit breaker or relay on
EACH of the Slide Switch outputs (Terminal 15, 16
and 17)

• Connect all power (not ignition) and ground wires

directly to battery. Implementing an in-line switch
will caus e al l accesso ry ou tp u ts to en er gize
momentarily. Devices such as gunloc ks , trunk release
etc. will be activated upon power being provi ded by
such a switch.

• Sound output will be severely reduced if any objects

are in front of this speaker. If maximum sound output
is required for your application, you should ensure
that the front of the s pea ker is clear of any obstruction.

• Install the speaker(s) in a location that provides

maximum signaling effectiveness and minimizes the
sound reaching the vehicle’s occupants.

1. DO NOT install equipment or route wiring or cord in

the deployment path of an air bag.

• Locate the siren so the vehicle controls can be

operated safely.

• In order for this electronic siren to function properly,

the ground connection must be made to the
NEGATIVE battery terminal.

• When drilling into a vehicle structure, be sure that

both sides of the surface are clear of anything that
could be damaged.

• If wiring is shorted to vehicle frame, high current

conductors can cause hazardous sparks resulting in
electrical fires or flying molten metal.

After In stallation

• After in stal lation , tes t the e lectro nic s iren an d spe aker

system to ensure that it is operating properly.

• Test all vehicle functions, including horn operation

and vehicle light systems, to ensure proper operation.

• After testing is complete, provide a copy of these

instruc tions to the ins tructio nal staf f and al l operatin g
personnel.

• File th ese ins truc tions in a s afe p lace an d refer to

them when maintaining and/or reinstalling the
product.

Failure to follow all safety precautions and instructions
may result in property damage, serious injury, or death to
you or others.

SECTION IV

INSTALLATION

SIREN / P.A. CONNECTIONS

ALARM

Applying a ground (-) to the ALARM terminal triggers the
siren to a distinct ive 2KHz sound. This function may be used
as a burglar alarm or a high-temperature alarm for K-9 carriers.
A motion-detector or switches at the trunk, doors, etc. may be
used for burglar alarms. A temperature switch (Part # UTAS)
is avail ab l e at an ex tra cost for a te m p er a tu r e alar m. A key
switch or concealed On/Off switch must be installed in-line
with the ALARM terminal.

FOOTSWITCH

A foot switch or any manual switch may be used in lieu of, or
in addition to, the horn ring. If the switch is used alone,
connect one swit ch terminal to ground (-), and connect the
other ter minal to th e RN G term in al. If a swit ch is used in
conjunction with the horn ring connections, connect one
terminal to RNG, and the other to (-) or (+) to match the horn
ring polarity.

HORN RING CONNECTIONS

Optional – Cut the vehicle horn circuit and connect the leads to
the HRN and RNG terminals on the back of the Touchmaster

For satisfactory lighting, it is rec ommended that the panel
lights (te r mi nal #1) be connected to the vehicl e light circuit
as shown.

The park kill feature of the Touchmaster Delta ™ uses the
Neutral Safety Switch to stop all siren sounds except P.A.,
Alarm, and Radio Rebroadcast. The Neutral Safety Switch
must be hooked up to the Park Kill input using Terminal
#14. A Park Kill Module must
between the vehicle and the Touchmaster Delta™.
(The Park Kill Module is available at an extra cost). The
Park Kill Module will
Touchmaster Delta™ from damage caused by transie nt
voltages. See Digital Circuitry Warning.

NOTE: The only wire connected to Terminal #14 s hould

be the GRAY wire of the UPKM-2. When testing this
feature, put the emergency brake on and verify siren
sounds in Reverse and Drive and that there is no sound in
Park or Neutral.
