Radio Mounting And Final Hook-Up - M/A-Com M7100IP Series Installation Manual

•
Occasional failure to enable siren or light functions via control head,
which can be temporarily resolved by either power cycling the radio or
turning the car ignition "off" and then "on" again.
To resolve these issues above, modify the Federal Systems control cable as
follows:
1. Remove the outer shell from the DB25 side of the Federal Systems
control cable.
2. Add a jumper from pin 1 to pin 19.
This modification to the SS2000 cable harness will disable the M7100
capability to turn on and off the SS2000 from the front of the control head.
The SS2000 will now be turned on and off strictly by its own ignition switch
trigger line (red wire from 12 pin Molex connector on SS2000 siren box).
Follow the SS2000 Federal Signal Corporation installation instructions to
attach the red ignition line correctly.

RADIO MOUNTING AND FINAL HOOK-UP

Front Mount
Typically, the bracket shown in Figure 19 is used for Front Mount
applications. The bracket can be mounted so that it is either above or below
the radio for the user's convenience. The bracket pictured in Figure 12 can
also be used for Remote Mount applications. The following instructions are
for a Front Mount installation using the bracket shown in Figure 19.
1. Use the supplied mounting bracket as a template to locate the position for
each of the drill holes. Be sure to leave enough room at the front and rear
of the radio for cable connections. Drill No. 27 (9/64) pilot holes.
2. Mount bracket with four 1/4"-14 x 3/4" sheet metal screws (use 1/4"-14 x
1-1/2" screws if needed).
3. Place radio into mounting bracket and secure with the four M4 x 10 mm
hex head screws, M4 flat washers and M4 lock washers supplied using a
No. 20 Torx driver.
4. Connect antenna coaxial cable to antenna connector (TNC).
5. Connect front mount accessory cable connector P1 to the Option/Remote
Control Connector (ORCC) and secure with the two captive screws in the
connector to the radio.
