Thanks Anthony
So you`d leave them in if they work ok with advice to phase out, as in no Definitive need to change out ?
Q & A / Re: Perko closers

Considering that they have been frowned upon in guidance such as that produced by the Guild of Architectural Ironmongers for over 30 years due to not being adjustable and prone to failure I was surprised the Government Guides didn't deprecate them, but they only specifically mentioned rising butt hinges.

Most fail the Section 10 basic checks as they fail to overcome the latch at either fully open or 15 degree open so get recommended to be replaced by an EN1154 closer anyway - for those that pass I still point out their issues and suggest phasing out as they fail.

What doesn't help is the fact that they can be found used on post 2000 & even post 2010 builds when you would have thought they should have known better than to fit them (even where an overhead closer cannot be fitted, there are EN1154 approved adjustable double cam/chain versions of the Perko they could use, but they stick to the cheap single chain version)

Are they self closing fire doors & if so do they need to be?

The Government Guides for dead ends usually give the option of fire doors onto the corridor (so they would need to be self closing and fire doors and  signed) or detection in every room (in which case they don't need to self close, be fire doors or be signed)

Hi Lyle,

many thanks for almost single handedly keeping this forum alive.

The table in the NIFRS Advice Note is a straight lift from Table B2 BS 7273-4:2015+A1 2021( Selection of category of actuation for release of electronically locked doors on means of escape from buildings )As you said NIFRS are offering "Advice" and BSI are providing "Guidance" although, if there is the question of approval of an Entertainment Licence application, it may well become prescriptive.

Presumably you have looked at this as part of the Risk Assessment and found it acceptable. The advice note states that it is unacceptable in "many" premises which implies that it is acceptable in some.

All you can do is discuss with the local Fire Safety Dept who, I would imagine, will cling very tightly to Advice Note 5 and say "but...alcohol" whilst making hypothetical statements about the "man (or woman) in the curly wig".

As anyone on here is only too well aware, this sector regularly experiences multi fatality incidents around the world so the Enforcing Authority is always going to err on the side of safety.
