Q AND A:
-------- 

Mike,

Below is an email I just sent to our AHJ, Capt. Steve Schowalter of 
the Wichita Fire Department -- he and I have both attended some of 
your seminars.  Steve and I would like to get your opinion on what I 
have requested, and we would like to know if you are aware of any 
other AHJs who have given permission for this communication method.  

--

Steve, 

We have a growing number of clients who want to get rid of all analog 
phone lines. To accommodate this, we seek your permission to use an 
alternate communication method for fire alarm systems. The code 
citations below are from the 2002 Edition of NFPA 72.

Honeywell makes a wireless communicator that is U.L. listed to replace 
both phone lines in a commercial fire system, but the wireless service 
is not available in our market. 

As you know, we have installed fire alarm systems that use one analog 
phone line for one communication path and an AlarmNet GSMCF cellular 
communicator for the second path. This communicator is U.L. listed to 
provide one communication path in commercial fire applications. What 
we would like to do for these clients is use two of the AlarmNet 
GSMCF units and no phone lines. 

8.5.2.2 permits alternate alarm communication methods that "provide a 
level of reliability and supervision consistent with the requirements 
of Chapter 4 and the intended level of protection."

The code interpretation issue is as follows: 8.5.3.2.1.4(A) says that 
"A system employing a DACT shall employ one telephone line (number). 
In addition, one of the following transmission means shall be 
employed." The list that follows gives several options, of which #2 is 
a cellular communicator.

When used with any current generation Honeywell fire alarm control 
panel, the AlarmNet GSMCF meets all of the requirements in the next 
section, 8.5.3.2.1.4(B). The AlarmNet GSMCF allows the control panel 
DACT to do everything it can do over a phone line, but the 
communication path is through the cellular network. Our monitoring 
center gets all zone information, all trouble and supervisory codes 
and signals, and we can even download the panel from our monitoring 
center. 

We believe that using two AlarmNet GSMCF units will provide a level 
of reliability and supervision that is at least equivalent and if not 
superior to two phone lines. Here are the reasons: 

1. There is equipment redundancy in the fact that there are two 
communicators instead of one, and we get a trouble signal if either 
communicator fails. 

2. With the dual cellular solution, each communicator sends its own 
daily test signal. With the standard phone line solution, a single 
communicator sends a test signal over each phone line every other day. 

3. The AlarmNet GSMCF must see two different cellular towers at all 
times or it generates a trouble signal – this gives us two separate 
signal paths, and these paths are physically (geographically) 
separated. We believe this is superior to the standard solution of two 
copper phone pairs that travel out of the building and usually quite 
some distance down the network in the same cable jacket with no 
physical separation – if that cable is severed, both paths are lost. 
With the cellular solution, one of the two towers can go down and we 
still have a signal path. 

---------------------------------------------------------------------- 

Hello Marsh,
 
... As to the Honeywell request, I agree that their alternative method 
meets or exceeds the minimum requirements.  Failure of either or both 
radios will result in a trouble condition immediately 
(within 200 seconds) within the central station, which exceeds the 
DACT (dialer) requirement to report a telephone line failure locally 
within 4 minutes and remotely within 24 hours. 

Best regards,

Mike 
 
This response should not be considered a formal interpretation but 
rather the author's opinion.
