Opening the Housing
Tools required:
• 3/8-inch socket
• 6-inch extension
To open the housing, loosen the four cover screws while supporting the housing, so it
does not fall. (The cover screws are retained in the housing.) The front of the unit is heavy,
but it is attached to the rear housing with a pivot hinge to allow ease of service. If the unit
requires service, replace the front housing, amplifier, and power supply (if equipped) as an
entire unit.

Wiring Power to the Control Board
JP6, JP7, JP8, and JP9 are all connected in parallel. Federal Signal recommends using
JP8 as the AC or DC input to allow room for wires coming in from the 3/4-inch NPT
opening. When power is supplied to JP8, it is connected through the PCB to the other
three connectors. If a connector is not being used, it is recommended to leave the
connector on the PCB. With I-IP100AC units, JP9 is wired from the factory to the power
supply PCB. With the I-IP100DC units, JP9 is wired to the amplifier PCB. Use JP6 and JP7
to wire external lights or strobes through JP4. A typical installation would use voltage to
be wired through the JP4 relays contacts or solid-state relay outputs.
NOTE: Current draw from JP6, JP7, and JP4 must not exceed 8.5 amperes AC or
5.0 ampere DC Max Combined Load.
