Rule 3.4.11 states Wiring from sprinklerwater flow devices and supervisory devices, housed in a water (weather) tight enclosure, shall be of a type suitable for "wet locations".

Lately we have been getting verification reports stating that the wiring to flow switches is not weatherproof even when the sprinkler valves are in a dry location. I had always wired according to the location and not used weatherproof wiring method like sealtite but dry flex or FAS armoured cable.

Anyone else noticed this, or getting called. The Building Inspectors want a clean verification report and we want to see they get it but this seems like overkill when the wiring method for the sprinkler room is BX or Loomex.

Never had this come back as a deficiency on verification. It seems like the default enclosure for all sprinkler junction boxes are for wet location, never seen one that wasnt - whether low air, tamper or flow. Who has been doing the verifications on the installations in question? I would guess most of the sprinkler rooms in the province do not comply with the ULC S524 rule you quoted.
