Is there a timeline when someone responds to these questions?
If someone doesn't want to read the question or provide an answer, that is up to them.
The xChange forums are not "official" NFPA responses.
So no - There is no timeline when a person must respond to any question posted in the forums.
What was the question?
We are a Government facility in California currently transmitting fire alarm signals to another Government facility via microwave antenna. Both sites no longer employ a radio technician to service the equipment when it has issues which makes it difficult to resolve in a timely manner.
We are planning to install dual path fire alarm communicators, IP with cellular backup. The issue that our IT department has brought up is that the cellular signals are provided by onsite repeaters that use our network and power to connect to ATT or Verizon and if we lose power we lose cell signals as well. There is no backup for the repeaters, no E-power, UPS or generators for those repeaters. We do have onsite IT & electrical support to bring the power and network backup if needed. We also have 24/7 security for fire watch and 24/7 on site county Fire Fighters.
I thought I saw something in NFPA 72 indicating that because of onsite support for IT we can comply with performance based methods. Our onsite AHJ stated that if we lose communication we will go on fire watch until it is restored.
Can you please advise with any helpful sections of NFPA 72 that may support this or any that say we cannot?
chiefns830 - Sir, this is the question from OP.
Rudy, I am not familiar with local authority requirements in California. I am not from the US - but from where I come, our local fire authority requires ALL emergency telecommunication systems to be provided with an automatic power backup even if there were 24/7 personnel stationed on site. This is stated clearly in the building codes.
The section you are referring in NFPA 72 (2019) could be #220.127.116.11 Management Organization. Also in various sections of the same, there are provisions for the dispatch of service personnel ("runner") to trouble site within certain time frame.

It may just be another internet troll trying to get us to say, "What was the question?"
