INSTALLATION
1.
Install the speaker (Item 8 in Table 4-3) in an area of the front or rear dash that will allow for proper
listening range with a moderate volume level setting. Use the hardware and mounting bracket
supplied with it. Refer to the speaker manufacturer’s instructions included in the speaker assembly kit
for additional installation guidance.
2.
Install the Speaker Cable Assembly (Item 9 in Table 4-3) onto the 2-pin connector at the rear of the
Control Head by visually aligning the ¾-moon-shaped keys of the connectors, and then push and turn
the outer locking ring of the cable connector clockwise until it stops. A mild click will be sensed to
confirm proper mating.
3.
CH-103 Control Head:
Connect the speaker’s 2-pin plastic connector to the mating connector on the
Speaker Cable Assembly.
CH-103PA Control Head:
A Speaker Y-Cable (part number MACDOS0015-NN050 for a straight
connector or MACDOS0015-RN050 for a right-angle connector) can be purchased in order to
connect the radio’s audio output to both the speaker (included in the Control Head Installation Kit)
and to the Federal Signal unit’s PA speaker. To complete these connections:
a.
Connect the Speaker Y-Cable’s 2-pin male connector to the Speaker Cable Assembly’s 2-pin
female connector.
b.
Connect the speaker’s 2-pin male connector to the female connector on the Speaker Y-Cable
assembly.
c.
Route the speaker cable through the vehicle’s channeling to the Federal Signal unit. Remove
interior panels, door kick panels, etc., as necessary. Protect the cable from possible chafing as
necessary.
d.
Using the supplied butt splices, strip and crimp the two wires of the speaker cable to the wires
of the speaker cable in the Federal Signal unit’s cable harness. Fifty feet of this wire is
supplied; cut off and discard any excess length. Polarity for this connection does not need to
be followed.
e.
Follow the installation instructions included with the Federal Signal unit to complete its
installation, if necessary.
4.
Route the excess cable(s) out of the way of casual contact and tie and stow it.
