I will take a look at NFPA 1221 and post the section I mentioned which references the portable coverage/vehicle repeaters.
I agree that systems cost a lot and I think its nearly impossble to have 100% portable coverage. I bet you could come close but thats why these simplex firegrounds are so appealing. Why go thru repeaters miles away when on scene communicatins can be accomplished with simplex frequencies... most of the time.
What if everyone just used the STOCS frequencies for firegrounds? Then we would all have some sort of interoperability if we at least on the same band. If not a ACU-1000 or one of these new boxs Steve Varney made could work.
A friend of mine built up a really sweet system in Durham. As a matter of fact he is still working on it. The nice part about it is the FD and EMS each have their own UHF frequency with 8 voted receivers. The FD's simplex fireground channel is also voted at the same 8 sites and microwaved back to VS where it can be recorded back at dispatch. I dont believe VS can talk back to them on it.. but why would they need to?
HERE IS A SHORT OVERVIEW OF WHAT NFPA 1221 COVERS FOR THOSE INTERESTED-
NFPA 1221 Standard for the Installation, Maintenance, and Use of Emergency Services Communications Systems Overview
This standard sets the minimum requirements for the installation, performance, operation, and maintenance of public emergency services communications systems and facilities (§ 1-1). NFPA 1221 characterizes a communications system as a vehicle that receives emergency signals (i.e. alarms) from the public and then forwards the appropriate information to emergency response facilities. Specifically, the standard addresses the functions, components, operations, testing and record keeping requirements of a communications system.
NFPA 1221 requires the following when developing a Communications System:
Procedures for various methods of communication
Public reporting
Dispatching
Telephoning
One-way and two-way radios
Description of functions of the communication system
Communication between the public (including automatic alarms) and emergency response agency
Communication within the emergency response agency
Communication among emergency response agencies
General requirements for a communications center
Location
Construction
Utilities
Fire Protection
Security
Power
Lighting
Wiring and cables
General requirements for the operations of a communication center
Management qualifications and training
Staffing procedures
Time recording
General requirements of call receiving equipment
Attributes of the emergency number 911
Fundamental requirements of the dispatching system including computer-aided dispatch (CAD).
Requirements for communication system testing and record keeping
