I have somewhat asked this question before.
Here is the link to the previous post
<URL url="Question regarding FA connected to CORE System text=“viewtopic.php?f=3&t=8145&p=73177&hilit=core#p73178”>Question regarding FA connected to CORE System
We have spoken with some local AHJ’s from different jurisdictions (Texas) and they basically told us we need to go to the state FMO. I am trying to compile code and standards about this issue so we can properly present it when we do. I have dug through NFPA 72, 96, 17A, 13, and IFC 2012. I have found some good references, but hope that maybe some of you can help me, so I may provide AHJ’s and FA companies definitive proof of what is required of them.
I guess I need to find something that says these systems MUST be monitored for trouble and supervisory signals. Alarm guys have refused to hook them up this way. And hypothetically speaking, if the wire to the kitchen system pull or heat detector was cut, then the system would not activate and the building would not go into alarm in a fire situation. It also would not produce a trouble signal to the FA Panel or central station.
• A traditional kitchen system activates the switch mechanically, I understand it is not the FA tech’s responsibility to test the mechanics of the kitchen system. But only that the switch transmits the gen. alarm signal. It is not possible to do that with these systems.
• So If you are unable to test a kitchen system because there is no micro switch, should the building FA be “yellow tagged”?
• The closest thing I can find in NFPA 72 is section 12.6.1.3 (see attachment). Though I am not entirely sure it is addressing my specific concerns. So maybe you can help here.
• I am not sure if this question falls under you all’s expertise, but if these systems require low voltage wire to be ran during installation, would it be required for the installer to have some sort of “low voltage license” in addition to their kitchen system license? I found this link here…

NFPA 70 has very little regarding low voltage wiring…
This post seemed better thought out in my head, but its late and I am tired of looking through code books. But whatever help you guys can provide would be greatly appreciated. Thanks!
