XP95 Sounder/beacon to go in -38c

[ElecTech]

Been called to a new site where issues are being had with a fire alarm which has had XP95 sounder beacons installed 2 years ago into a blast freezer/chiller area. The area gets down to -38c. The sounders are starting to go into fault & the spec says -20c I think.

 

Anyone know of any XP95 sounder beacons that can withstand the low temp OR a solution with some sort of enclosure which can keep them ambient temp but the sound not affected. There around roughly 10/15 sounders in there but are apart of a 120 device loop.

I'm sure they're is a conventional sounder capable, so just stick a sounder controller on the loop (psi needed) and good to go

-38 is proper cold, I reakon that is specialist area. What do you use other than kit designed for minus 20?

Yeah it is specialist, its almost like a blast freezer, I don't believe staff are in there when it goes down to those levels but regardless the sounders will need to be present when they are inside at say -20c.

Yeah I'm sure that would work but cant find the sounder capable. What's a PSI by the way?

 

Having not been to site I'm interested to how its wired as just been checking the FP200 spec & that's only rated down to -20c.

 

I will update once I know more.

Ah ok, yeah understood nice one.

Iv found a beacon that goes down to -50c

 

Would a beacon solely be sufficient without the sound? Is there regulations to say sound has to be primary and a flashing beacon as a secondary visual?
