INTRODUCTION
WIRING INSTALLATION
The 30.2100 siren amplifier powers one 100
watt RMS speaker. The 30.2100 siren
contains a rotary switch for mode selection,
three push button switches, and an on-off
volume switch. This siren is capable of
producing sounds commonly known as Wail,
Yelp, Phaser, and Airhorn. The 30.2100 also
features an intersection mode. Use only one
100 watt speaker with an 11 ohm
impedance.
BLACK AND BLACK-Connect one conductor
of the 16-2 wire to the terminal on the siren
marked "SPKR COMMON". Connect the
second conductor of the 16-2 wire to the "100
WATT" terminal on the siren. Route 16-2
speaker wire from the siren, to the front of the
car to the speaker. Be certain to protect the
wire from abrasion and cuts as it passes
through the fire wall and other potential problem
areas. Cut off any excess wire, and connect to
the speaker terminals. When using one
speaker, polarity is not a factor.
INSTALLATION OF SIREN WITH
MOUNTING BRACKET
YELLOW (optional)- Connect to terminal
marked Horn Input. Run through fire wall and
connect to vehicle horn. (See TAP feature)
Select a location suitable for installation of the
siren. This area must be free from moisture,
heat, abuse. Take special care to be certain
the siren is not mounted in the deployment
area of an airbag! Using the mounting
bracket as a template, mark the location of
the mounting holes. Drill holes at these
locations to assist in starting the mounting
screws provided. Mount the bracket, and
then mount the siren to the bracket using the
supplied screws and washers. When using a
horizontal or vertical equipment rack, use of
enclosed mounting bracket is not necessary.
BLUE- Attach one wire to the Radio Input(-).
Attach second wire to Radio Input(+). Then
route one of these to one side of two-way radio
speaker and the other to the second side of
two-way radio speaker. Note: If while testing
after installation, a garbling of radio rebroadcast
is noticed, reverse the wires at the two-way
radio speaker.

RADIO-The audio from the 2-way radio is
rebroadcast over the outside speaker. The
AIRHORN, PHASER, INTERSECTION MODE,
and P.A. will override the radio rebroadcast.
NOTE: Volume for the Radio Rebroadcast is
pre-set at the factory. Volume can be adjusted
by removing the siren cover and locating the
potentiometer on the left side of the circuit
board. Using a small slotted screwdriver,
adjust to desired volume.
BLACK-Connect the black wire to the
terminal on the siren marked "GROUND".
Connect the other end of the black wire to
ground.
RED-Connect the red wire to the terminal on
the siren marked "+12 VOLTS". This terminal
on the siren connects directly to the on board
20 amp fuse. Connect the other end of the
red wire to a positive source. To protect the
wiring going to the siren, install an in-line fuse
or circuit breaker on the end of the wire as
close to the positive source as possible. The
current draw of the siren during operation is
approximately 8 amps, when supplied by 13.8
volts. The current draw of the siren when
power is applied, but no functions are
selected is approximately .03 amps.
Note: When in Radio Rebroadcast mode
current draw is approximately 1.5 amps.
STANDBY-If the "INTER" push-button is
depressed in this mode, the intersection tones
will be produced. If the "HORN" push-button is
depressed, the air horn sound will be produced.
If the PHSR push-button is depressed, the
phaser sound will be produced.
WAIL-This position produces the "WAIL" tone.
Depressing the INTER, HORN, or PHSR
push-buttons, while in WAIL position, will
produce their individual sounds. P. A. will
override.
SIREN FUNCTIONS
ON/OFF SWITCH turns on the siren and
controls the level of the P.A. audio produced
by keying the microphone and speaking into
it. This control does not affect the level of the
siren tones, nor does it control the radio
rebroadcast audio volume heard on the
outside speaker.
YELP-This produces the "YELP" tone.
Depressing the INTER, HORN, or PHSR
push-buttons, while in YELP position, will
produce their individual sounds. P.A. will
override.
P.A.-The P.A. will override all other siren
functions, but the preferred mode for operation
of the P.A. is STBY.
TAP-When in this mode, tap the AIR-HORN
push-button one time for the WAIL sound.
Tap again for the YELP sound. Tap twice
quickly at any time and the mode stops.
NOTE: Vehicle horn ring will operate these
functions when the yellow wire has been
connected between the horn input terminal
and the vehicle horn. OPTION: The same
features above can also be achieved by using
the SHO-ME ® 30.0107 momentary foot
switch. For foot switch operation attach
yellow wire to black wire of the foot switch
(not included) attach red wire of the foot
switch to 12 volts positive.

TROUBLE-SHOOTING
The following list contains some of the most common siren problems and their most probable causes. Most of the
problems listed deal with installation or mechanical problems external to the siren electronics. PLEASE review list
prior to consulting the factory or returning your unit for service.
1. No output, or backlighting.
a. Siren amplifier not connected to power
source.
b. Internal 20 amp. fuse blown.
c. Vehicle supply fuse blown.
d. On/Off switch in Off position.
5. Siren volume low.
a. High resistance in speaker wiring.
b. Low voltage to siren.
6. Siren sounds air horn at all times.
a. Remote horn wiring from terminal
shorting to positive.
2. Internal 20 amp. fuse blown.
a. Reverse polarity at terminal block.
b. Short circuit in speaker wiring.
c. Defective speaker
d. Shorted output transistors.
7. P. A. volume too low or no P.A. at all.
a. Defective microphone.
b. Microphone not completely plugged in
(inside).
8. Radio rebroadcast volume low or distorted.
a. Potentiometer not adjusted properly
(inside).
3. No output from speaker- Siren tones heard
inside amplifier chassis.
a. Speaker not connected.
b. Open circuit in speaker wiring.
c. Defective speaker
9. High rate of speaker failure.
a. High voltage to siren made for 13.8v.
b. SPKR. Mounted improperly for water
drainage.
4. Siren tones sound garbled.
a. Low voltage to siren amplifier.
b. Defective speaker.
