The Honeywell IP/GSM4G transmitter was approved by the FDNYfor use in NYC in 2013, FDNY COA #6150.
One of the requirements listed in the COA reads as follows:
3.2The failure of any one channel shall be annunciated at the central station within five (5) minutes of failure by the remaining active channel.
The new Honeywell IP/GSM4G units no longer permit the fault time to be programmed as five (5) minutes . (The minimum time now programmable is one hour.)
As a result, any units installed going forward which do not permit a five (5) minute fault time will not pass an FDNY inspection.
