Specifications

Proposal Number PSDF #P09-0004
 Universal System Manager (USM) - The USM device shall be the CAN network controller
and provide various functions to the apparatus such as load management. The USM shall be
programmed from a network interface to a PC computer.
 Power Distribution Module(s) (PDM) - The PDM shall be a control device on the network
with a primary function as power distribution. Receiving control signals from the USM the
PDM turns on and off relays providing power to its connected loads. The PDM also shall
contain digital switch inputs allowing for input clustering throughout the apparatus.
 Information Display Module - for displaying text, warnings and diagnostics. The information
Display Module shall allow the fire department to access and change load management
shedding priority and maintenance text listing the routine maintenance items and lubrication
capacities on the apparatus.
 Input / Output Module - The module shall have 16 inputs to communicate with the USM and
3 outputs for various chassis functions.
The system shall provide diagnostic capabilities for troubleshooting the electrical system of the apparatus.
CHASSIS COLOR CODED WIRING
All chassis wiring shall be type "GXL" in accordance with S.A.E. J1128 and NFPA-1901. ALL wiring shall
be COLOR CODED and continuously marked with the circuit number and function.
All wiring to be covered in nylon heat resistant "HTZL" loom rated at a minimum of 300 degrees F
exceeding the heat requirements of NFPA-1901.
A battery "loop back" ground circuit shall be supplied for the EDS system to reduce the possible effects of
Electromagnetic and Radio Frequency Interference.
The chassis cab, engine and transmission shall be electrically bonded to the chassis frame rails with braided
ground straps.
ELECTRICAL SYSTEM CONNECTORS
All multiple conductor electrical connections shall be made with electrical connectors. The connectors shall
become mechanically locked when mated.
All single wire terminations requiring special connectors with a ring or spade terminal shall be crimped, and
wrapped with heat shrink tubing.
FIRE COM INTERCOM SYSTEM
There shall be a Fire Com intercom system installed in the chassis cab. The intercom system shall be
installed and have all wiring and components to render the system operational as follows:
One (1) 3020R series intercom system features:
For use with two radios
Voice-activated circuitry (VOX)
Continuous mobile radio monitoring
Independent controls allow quick adjustment of volume and squelch
Durable steel housing protects against heat, moisture, and damage from impact
Dual radio monitoring and transmit selector switch.
