Fire detection in photo dark rooms

[fireftrm]

Indeed I have learnt something today, and apologise in turn!

[Benzerari]

Also this remind me of a couple of times, I have been blamed when changing the type of detector from smoke to heat detector, it was in a corridor and close to the shower each time the door is opened the steam sets false alarms, I have been told to recommend repositioning of the smoke detector rather than replacing it by heat detector, because the decision of what type of detector is the decision of the fire officer and it is not for the service engineer to take the decision... that's what I have been told if I am wrong please feel free to correct me.

this may apply to your case CJ

Thank you

I don't think it is quite right to say that the type of detector is up to the Fire Officer, assuming the FO you refer to is from the Fire Service.
The type of detector is dependant on many variables and the decision would be up to the RP in consultation with the installer, taking into consideration the advice contained in the BS.

and the installer in consultation of what? and who?

smoke or smoke/combustion detectors in corridors no heat.
You need to give early as possible warning of a fire in the escape routes before they become overcome by smoke and impassible.
The heat would mean that the corridor was on fire.

Multisensor as mentioned would have been the best option.

multisensor with the selected mode that combine heat and smoke detection isn't it ?

There is something new to me in this topic, to be honest!

thanks to the contributors

that's the one. a optical/heat is still classed a smoke detector

A fire alarm engineer can give advice as to possible changes to automatic detector types already installed. The Responsible Person takes responsibility if they accept and act on that advice. Responsible Persons would be well-advised to consult and receive agreement for such proposals, in advance, from interested parties such as the building user, the building owner, the building insurer and any authority responsible for enforcing fire safety legislation for that building.
