Fig. 3
Wire the speaker to Common and 58 (58 watt) or Common and 100 (100 watt) using the #18 "Zip
Cord" supplied. Connect the "Zip Cord" to the speaker wires with (2) wirenuts. Determine which
speaker you have prior to connection. Connection of a 58 watt speaker to the 100 watt terminal will
destroy the speaker. Ground [earth or (-) terminal] the unit to the vehicle frame using the #16 gauge
black wire and #8 ring terminal. Install #16 fork terminals on the red, white and yellow wires (one end
only). For Model 3050, also install a terminal on the green wire in a similar manner. Install the red,
yellow and white wires on the center off switch as shown in Fig 3. On Model 3050, also install the red
jumper wire (between the switch and the push-button), and install the green wire on the push-button.
After making sure that all connections are tight, install the switch (and push-button for Model 3050) in
the mounting bracket. If mounting the Beacon switch in the siren switch bracket, install and wire it at
this time. Do Not Wire the Beacon and Siren on the Same Power Feed Line. Use separate
supply wires and fuses. Connect the white wire to the terminal marked (+) in the siren. Connect the
yellow wire to terminal B at the siren. For Model 3050, connect the green wire to terminal A at the
siren. Replace the siren cover. Be certain the wires are not caught between the cover and chassis.
Replace the four cover screws. Place the center off toggle switch in the center position. Using a
wirenut, connect one end of the in-line fuseholder to the red wire coming from the center off switch,
as close to the power take off point as possible. Connect the other end of the in-line fuseholder to
either the battery positive terminal or to the starter solenoid positive post. A 3/8" ring terminal is
supplied (if needed) for this purpose. Insert the 14 amp fuse in the in-line fuseholder.
OPERATION
"Wail" and "Yelp" tones are in some cases (such as in the state of California) the only
recognized siren tones for calling for the right of way. Ancillary tones such as "Air Horn" 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 momentarily shift from the primary tone as an indication of the imminent
presence of an emergency vehicle.
Model 3000 - This siren is controlled by a center off, remotely mounted switch. Up is the wail option and
down is the Yelp option.
Model 3050 - Same as Model 3000, it also has a push-button for the Airhorn option.
Testing the Siren
For Model 3050, with the switch in the Off position, depress the Air Horn button. The Air Horn
should be heard.
