Servicing the Convergence Network System
Federal Signal recommends that the siren amplifier/relay module and control
head be returned to your local distributor or Federal Signal for service. External
components such as cabling, fuses, and the red and black insulators are available
as replacement parts. See Table 10 on page 60. With the exception of the slide
switch in the control head, there are no other user-serviceable parts within the
control head or the siren amplifier/relay module. After servicing the system, test
it to ensure that it is operating properly. For more information, see “Testing the
Convergence Network Installation” on page 46.
Replacing the Slide Switch
The slide switch can be removed from the control head for replacement or service
without disassembling the entire control head. The slide switch is secured to the
front of the control head by a bezel and two 1/4”-20 by 3/4-inch screws. The switch
is connected to the four-pin J3 connector on the back of control head assembly,
which lies below the logic control and power control PCBs and is easily accessible.
STATIC-SENSITIVE DEVICE: The control head circuitry can be damaged by
electrostatic discharge (ESD). Follow anti-static procedures while removing
the slide switch.
Tools needed:
• 7/16-inch nut driver
• Small Phillips screwdriver
• Small needle-nose pliers
• 1/64-inch hex key wrench
Dismounting and Disconnecting the Control Head
To remove the control head:
1. Use a 7/16-inch nut driver to remove the two 1/4-20 by 3/4-inch hinge screws
securing the two mounting brackets together. Retain the screws and the two
1/4-inch external-tooth lock washers. See Figure 37 on page 55.
2. Remove the two #6-32 by 1/4-inch Phillips screws securing the bracket to the
rear of the control head. See Figure 38 on page 55. Retain the screws and
the two #6 lock washers.
3. Disconnect the cables and leads from the back of the control head.
