Power Distribution Connections ("L4" Models)
A #8 stud is provided on the rear of the unit and is intended for use ONLY as a convenient ground (earth) " tie-point " for
the light bar wiring. It is not an adequate ground (earth) for the siren or the light bar. It is recommended all ground
(earth) wires attached here be terminated with a crimp-on ring terminal.
11-Position Terminal Block - Lighting Control - (See Wiring Diagram page 16)
IMPORTANT!
Remember auxillary outputs A, B & D on L4 models can supply a maximum of 20 Amps each for a combined total
of 30 Amps. Install appropriate fuses in each output wire as close to the siren as possible.
T1 - SW C COM - Common or power feed for Auxiliary Switch "C". Terminals are a SPDT circuit that may be connected
as a momentary (or latching depending on the switch ordered) ignition controlled circuit, or used for switching auxiliary
circuits. It will Handle 10 Amps, and should be protected with a fuse at the battery if individually fed.
T2 - SW C NC - Connect to the load to be controlled by the normally-closed contact on Auxiliary Switch "C".
T3 - SW C NO - Connect to the load to be controlled by the normally-open contact on Auxiliary Switch "C".
T4 - AUXILIARY SW A, connect to the load to be controlled by Auxiliary Switch "A".
T5 - AUXILIARY SW B - Connect to the load to be controlled by Auxiliary Switch "B".
T6- AUXILIARY SW D - Connect to the load to be controlled by Auxiliary Switch "D".
IMPORTANT!
The total combined current for the auxillary outputs A,B & D Must not exceed 30 Amps total.
The speaker's sound projecting opening should be pointed forward, parallel to the ground, and not obstructed or
muffled by structural components of the vehicle. Concealed or under-hood mountings in some cases will result in a
dramatic reduction in performance. To minimize this reduction, mount the speaker so the sound emitted is projected
directly forward and obstruction by vehicle components such as hoses, brackets, grille, etc. is minimized.
Electromechanical sirens and electronic siren speakers should be mounted as far from the occupants as possible
using acoustically insulated compartments and isolation mountings to minimize the transmission of sound into the
vehicle. It may be helpful to mount the device on the front bumper, engine cowl or fender; heavily insulate the pas-
senger compartment; and operate the siren only with the windows closed.
Each of these approaches may cause significant operational problems, including loss of siren performance from road
slush, increased likelihood of damage to the siren in minor collisions, and the inability to hear the sirens on other
emergency vehicles.
APPROPRIATE TRAINING OF VEHICLE OPERATORS IS RECOMMENDED TO ALERT THEM TOTHESE PROB-
LEMS AND MINIMIZE THE EFFECT OF THESE PROBLEMS DURING OPERATIONS.
