I do vaguely recall this a few months ago on the forum and forget what we
came up with, so here's just my thoughts before breakfast ...
The standards do not specifically call out a requirement for nail plate or
protection of piping. However, depending on which codes are in effect at
the location
Thanks Chris and everybody, this is the information I was looking for.

It will usually stop a drywall screw, until the drywall guy decides that he
absolutely needs a screw right there and uses a self taping screw. (This just

The air flow over the surface impacts how quickly the link or car
heats up but not how hot it gets since that is a function of the
exposing temperature. We could dug up the old heat transfer equation
for convection but I don't think many really want to go that far.
Naturally there is an

As taken from the literature It has been found that fusible link elements
which are used to support loads in various devices and in particular in

changes in temperature,
Does an air compressor for a pre-action system have to be wired on a

It's a good idea if you need to service the compressor, but I don't think
it's required in NFPA 13. Maybe in the elec. Code.

I did this a couple of years ago by direction of the AHJ - I didn't agree

NFPA 13 does allow adjacent buildings to be served by a single riser but the
conditions are limited. The intent of the committee at the time this
proposal was accepted was to allow a cost effective means to get fire
protection to auxiliary buildings (like schools) or out buildings

You will have to go by the listing for the sprinkler. If it is
specifically listed for Light Hazard only, you can't use it for OH.
If it is listed for use in NFPA 13 occupancies, it could be used in
Light or Ordinary. The Tyco RFII can be used in on OH occupancy, such

Compressors, couldn't find anything specific in Electrical code or 13. Just
make sure there's a low pressure alarm (NFPA 13, 7.9.2.2) incase the compressor
is shut off or fails.
