Several years ago, a code consultant for a city in CA stated that she didn't like individual preaction valves or flow switches for elevator shafts or elevator machine rooms because there was too much of a chance that the shunt trip could operate unnecessarily during testing or surges. She liked wet pipe systems and lower temperature heat detectors in shafts and elevator machine rooms. Since that time I have only used wet pipe systems and heat detectors connected to the shunt trip. Makes life easier and you don't even have to directly tie into the fire alarm system.
Hopefully, I am not missing something.

I think you'll need a deluge valve or pre-action. but I will wath the list eagerly and learn from others. C.

Anyone know of one (1-1/2 inch or smaller) that is listed for fire protection service? Yes, apparently I really need to install sprinklers in the hoistway. It is of the "no machine room" type but uses combustible belts for lifting the cars. I am trying to avoid using a listed deluge valve. Thanks.
