Guest guest Posted February 9, 2017 Report Share Posted February 9, 2017 i recently carried out a FRA of a converted house, which a local authority bought over and changed the use to a hostel/ temp accomodation for homeless. Several fd's were nit closing fully, i stated the closers require adjusting to allow the door to close fully. This did not work and an engineer is saying its must be a vacuum in the room. Has anyone came across this and have any possible solutions? Quote Link to comment Share on other sites More sharing options...
Tom Sutton Posted February 10, 2017 Report Share Posted February 10, 2017 I have been involved where wind pressure on one side of a building and low on the opposite side has prevented the doors on the high pressure side not to close properly. However I can see see in a well insulated room with an extractor fan or something similar, a partial vacuum could be created, preventing the closer properly closing the door, but if you open a window this will equalize the pressure and the door should shut normally.

Guest dennis field Posted February 27, 2017 Report Share Posted February 27, 2017 I work on maintenance in an old peoples retirement home where door closers on each room operate at fire emergency times.as you can expect many of the old folk need their room Windows closed at all times which means closers won't close completely because of vacuum/air pressure.I am trying to solve this problem with spring loaded air flaps on inside of airbrick.l need to locate flaps.any help would be appreciated.

Tom Sutton Posted March 4, 2017 Report Share Posted March 4, 2017 I would suggest you surf the web for "air vents with anti draught excluder" and I came up with http://www.ebay.co.uk/bhp/anti-draft-vent. Quote Link to comment Share on other sites More sharing options...
Guest Carpenter Posted November 25, 2018 Report Share Posted November 25, 2018 I'm having this exact issue--fire door with commercial closer will shut fully, but won't latch when there is no airflow available--but when an adjacent door is cracked to allow air flow, the fire door latches fully.

Tom Sutton Posted November 26, 2018 Report Share Posted November 26, 2018 I would think the solution for dennis will apply to you. Quote Link to comment Share on other sites More sharing options...
Safelincs Posted December 13, 2018 Report Share Posted December 13, 2018 If the fire door does not close due to the resistance of the latch/air pressure you need a fire door closer with "latching action". The Geze TS4000 for example has the latching action as well as plenty of power to close even heavier doors reliably. However, there are many other makes and models as well.

Guest Vacum problem! Posted December 28, 2018 Report Share Posted December 28, 2018 I took your advice, Safelincs. I fitted Geze 4000 to the doors. Set to very near maximum. It only went and worked on the non-ventilated rooms. The firedoor did not slam badly when the window was open. Thank you. Quote Link to comment Share on other sites More sharing options...
Guest WINDY Posted March 23, 2019 Report Share Posted March 23, 2019 Communal door to block of flats does not self close in windy conditions. The door opens inwards. If the door opened outwards would it close because the wind would push it shut ? Should communal doors act like fire doors and self close in windy conditions ?

Neil Ashdown MAFDI Posted March 27, 2019 Report Share Posted March 27, 2019 The door must self-close. Therefore efforts should be made so that it does self-close and remain closed accordingly. Quote Link to comment Share on other sites More sharing options...
Tom Sutton Posted March 27, 2019 Report Share Posted March 27, 2019 When you say, "Communal door to block of flats" do you mean the final exit door to the public thoroughfare. Quote Link to comment Share on other sites More sharing options...
Neil Ashdown MAFDI Posted March 28, 2019 Report Share Posted March 28, 2019 Good point, Tom. In which case, it would most likely not be a fire resisting door and therefore would not need to self-close. Quote Link to comment Share on other sites More sharing options...
Guest JAck Posted April 2, 2019 Report Share Posted April 2, 2019 wouldn't you want front doors to the communal to close to ensure no access for a wannabe Arson.. ? Quote Link to comment Share on other sites More sharing options...
Tom Sutton Posted April 4, 2019 Report Share Posted April 4, 2019 I agree with you Jack but the RR(FS)O is about escaping from fire not security. Quote Link to comment Share on other sites More sharing options...
Guest David Posted May 31, 2019 Report Share Posted May 31, 2019 I've had 3 fire doors fitted. Two are closing fine but one wont close fully and closes very slowly. I've changed the perko but it made one difference. All 3 are close to each other on the same landing. Any ideas? Quote Link to comment Share on other sites More sharing options...
AnthonyB Posted June 1, 2019 Report Share Posted June 1, 2019 Whilst still sold most models of Perko chain are not to current standards for fire doors and have indeed been advised against since the 90's because of their unreliability - an EN1154 compliant device should be used. A lot of fire safety products are miss-sold and many adverts for 'fire door compliant' chain style closers are only tested to BSEN 1634-1 for fire resistance and do not meet the actual standard for closers BSEN1154 Quote Link to comment Share on other sites More sharing options...

Guest Sandesh Posted July 14, 2020 Report Share Posted July 14, 2020 If the door facing is a fire retardant ply, you can install a fire rated door grille. Quote Link to comment Share on other sites More sharing options...
Guest Jav Posted October 9, 2021 Report Share Posted October 9, 2021 Hi we came across this in a living room installed 2 fire door with closer in a small living room with one door open the other door works fine and vice versa but with one door closed the other will not close fully unless the closer it set to max and then it slams shut anyone have fix for this pls Quote Link to comment Share on other sites More sharing options...
Neil ashdown Posted October 20, 2021 Report Share Posted October 20, 2021 This can be difficult to resolve, you may need to invest in a high-power-size cam action self-closing device with an adjustable latching action. Speak to a competent architectural ironmonger or a self-closer manufacturer for advice. When adjusting the closing speed its best to set the speed to quite slow so that the air can escape more easily (reducing the vacuum) as the door closes.
