Servicing the Pathfinder
Federal Signal recommends that the siren be returned to your local distributor or
Federal Signal for service. External components, such as cabling, are available as
replacement parts. (See Table 7.) Except the slide switch in the siren, there are no
other user-serviceable parts within the unit. After servicing the system, test it to
ensure that it is operating properly.
Replacing the Slide Switch
The slide switch can be removed from the siren without removing the siren from
the vehicle in most installations.
STATIC-SENSITIVE DEVICE: The light bar circuitry can be damaged by
electrostatic discharge (ESD). Follow anti-static procedures when removing
the slide switch.
Figure 12 Keypad Removal
To replace the slide switch:
1.
Use a T20 Torx driver to remove the four 8-32 shoulder screws securing the
keypad to the extrusion (Figure 12).
2.
Disconnect the ribbon cable and microphone lead from amp PCBA.
3.
Gently unsnap the siren bezel from the keypad (Figure 13).
