Hi All, 

Does anyone have information or advice where I can locate this information, on requirement for heat/smoke detectors?

I have two walk-in cold rooms that are joined. You walk from the warehouse into the -20 cold room, through a manual sliding door. At the rear of the -20 is a manual door that leads into a -27 cold room. Neither of these doors has a window. The room are around 10ms and 16m2 so not very big. They also have preson trapped alarms which switch off the system if activated. 

We use the -27 cold room to store packaging and if the cold room has a lot of packaging it sets the fire alarm off when the refridgeration system does a defrost, although there is a verys small change in temperature, not enough to set off the alarm, according to our fire system contractor. The contractor does however suggest we remove the system in these cold rooms or install an aspirating system, which would cost around £10 000 to install. 

So I need to determine whether we can remove the fire alarm system from these cold rooms or whether it is required as there is a room leading into another room. The likelyhood of fire is extrememly low at -20 degrees. 

Thanks for any advice

Dylan
