  2. I am not aware of such a ruling could you enlighten me the origins of the ruling.
  3. Many thanks - I’ll take a look 🙂
  4. The guide for such premises is HOUSING – FIRE SAFETY Guidance on fire safety provisions for certain types of existing housing and includes advice on fire alarms.
  5. It appears you want to convert the two flats into a maisonette with the option of returning to the status quo if you choose later. I cannot give a definitive answer without a physical inspection but providing all the doors to habitual rooms meet the required fire resistance I cannot see why the building control would not accept it.

    Mr

    I cannot understand where the landlord got his advice from but it sounds like your proposals are satisfactory providing the magnetic lock is installed according BS 7273 4.
  7. The purpose of the cold smoke seals on the flat front door is to prevent a fire in a flat smoke logging the common areas. Smoke seals on corridor doors are to prevent a protected area smoke logging another protected area. But it looks like they realised their mistake by rectifying the front doors.
  8. I have been working recently in a number of buildings which have been converted into flats from previous uses as warehouses or factories. There seems to be no pattern as to what fire alarm system is provided. Generally, compartmentation seems to be sound. Fire doors are fitted, common parts kept sterile etc. As it is often impossible to tell the date of conversion I am wondering as a general rule of thumb, what level of fire alarm system should be provided? The buildings tend to occupy 3-6 floors and anything from 10-30 flats. Should common parts have smoke detection provided?

    Mr

    Hi, I have an industrial unit of approx 3000 square feet. The max travel distance to the one hour fire corridor is 14.5 mts. The fire corridor is accessed from inside the unit through a 1 hour fire door with a push pad. I was hoping to install an external door with a fail safe electric strike/intercom and beyond that a roller shutter than would be closed on leaving the unit at the end of the day for security. My landlord reckons this is not permitted for fire safety reasons. Could you offer any advice on if this acceptable. There are a very limited number of members of the public who visit the unit as we are an e commerce company.
  11. Some fire risk assessors would be a little concerned but providing you maintain an escape route of 1050 mm and level going, you appear to conform to article 14 of The Regulatory Reform (Fire Safety) Order 2005. Check this out with your FR assessor.
  12. Has to be using test smoke/heat. If they aren't then they are doing the equivalent of what in the extinguisher trade is known as 'rag & tag' i.e. not actually doing anything other than filling in the service label/report & adding a tamper tag. Wouldn't surprise me if they don't open up the panel and check the panels with a test meter either. Far too many con artists out there in the fire trade. From the British Standard for Fire Alarms: c) Every heat detector should be functionally tested by means of a suitable heat source, unless operation of the detector in this manner would then necessitate replacement of part or all of the sensing element (e.g. as in fusible link point detectors or non-integrating line detectors). Special test arrangements are required for fusible link heat detectors. The heat source should not have the potential to ignite a fire; live flame should not be used, and special equipment might be necessary in explosive atmospheres. d) Point smoke detectors should be functionally tested by a method that confirms that smoke can enter the detector chamber and produce a fire alarm signal (e.g. by use of apparatus that generates simulated smoke or suitable aerosols around the detector). It should be ensured that the material used does not cause damage to, or affect the subsequent performance of, the detector; the manufacturer’s guidance on suitable materials should be followed.
  13. Where walls are dot n dab on masonry party and external walls and not on the fire line escape route are intumescent "putty" pads required? Thanks for any advice.
  14. Hi all I wonder if you can help. I've previously seen fire alarm service companies use long poles to puff smoke into detector heads as part of the routine service of the fire alarm. During a recent inspection and visit to a site when I was discussing this, the site indicated that this never happens and they are certain of this. I'm not sure if there are other ways to check the detector heads. If anyone can help clarify how smoke detector heads should be serviced that would be great. Does it need to be manually checked in this way or can it be done remotely / via electronic signals Any help would be appreciated Kind regards
  15. I have a follow-up question. As I mentioned the smoke seals on our individual apartment entrance doors have been rectified; this was on the side and top edges. The bottom edge of the doors incorporates a rebated drop-down door seal as the door-edge to cill gap is about 10mm. However when the door is closed the seal when dropped still leaves a gap of about 2.5mm. I appreciate this is less than the 3mm limit for a door-edge to cill gap where no smoke seal would be required, but I would have thought that where a smoke seal is fitted it ought to bridge the gap completely, especially as with the drop-down type there's no risk of interfering with door self-closure. ----------------------- Thanks for that Neil, much appreciated. I will request product installation data sheets from the building managers to clarify the required gap, although I would expect that for a frame fitted with an integrated intumescent strip and brush-type smoke seal anything greater than a 4mm leaf-to-frame gap would in any event render the smoke seal ineffective. The entrance doors to individual apartments in the building have intumescent strips but the smoke seals are separate and of a plastic blade type. Although the apartments are new I identified that my apartment door smoke seal was damaged, and that of a neighbour was not present; I looked at other apartments and found that several more were also defective. I got an initial response back that as the corridor fire doors had effective smoke seals (see my earlier post!) then that would prevent smoke from entering apartments (despite there being several apartment entrances between sets of fire doors. Eventually someone saw sense and new smoke seals were installed on the affected apartment doors.
  16. Most fire doors have three hinges but it depends how it was tested, this information should appear on the documentation that comes with the door set and could have passed using two hinges. Check out BS EN 1935: 2002.
  17. Dear Mr Sutton Many thanks for this. Please see attached a drawing of the area, in red where it says "wall we want to open" is where the fire door will go. We own the 2 flats, although for council tax purposes they remain as 2 dwellings. This is because to unify them we had to demolish one kitchen and we may want to sell in the future (take door and build wall again). I hope it makes sense. Please do ask if unclear. Best wishes and thanks again for your time Di option 1.pdf
  18. Thanks for the comments. The floor spring door closers may be an option and I will put that forward for comment.

  20. Hi, if the third hinge is to prevent the door bowing, why do aluminium frames, in a typical fire and sound partition, only ever have 2?
  21. Possibly. Easiest way to tell is to switch all the lights off and see how easy it is to see your way out, you usually need the equivalent light of a full moon on a clear night to safely see your way out (this is where the original EL lighting levels came from!). Consider the available light at the start and end of the day (when it's darkest), time of year and the impact of overcast weather. Having done this you may conclude you are fine. If not then depending on the size of the offices and number of people you may need either emergency lighting - or torches!
  22. If it's an antibarricade door you need to use fire door rated Floor Spring Door Closers, I have a local authority client whose Childrens Homes needed bedroom doors to be anti-barricade but also self closing FD30s doors https://www.gjohns.co.uk/door-controls/floor-springs-door-closers.html

    Sounds like you need an out of hours call out, costly but at least they will see the issue. The cause needn't be the panel and could equally be the wiring or a device, I'd not want to replace the panel until sure it was the culprit.

    Mr

    Sounds like commercial sleeping risk (i.e. not a dwelling), should be an FD30s doorset if it's protecting the escape route. This should have been picked up on your Fire Risk Assessment
  25. Hi Adrian, not sure if have understood the full picture. However, if you are looking for a concealed fire door closer that offers protection from the user being trapped by the fire door, I could recommend the Powermatic from Perko. This fire door closer is concealed but more importantly is a free-swing door closer which allows the fire door to operate like an ordinary, closer-free door. When the fire alarm system trigger the fire door is of course shut automatically. Harry
  26. I wonder if anyone has come across this problem before. A supported living scheme is to provide a home for one young man with very high support needs. There will always be 3 staff to one resident. Apparently standard self-closers cannot be used on the fire doors because of tampering risk from resident. I suggested Perko or Perkomatic be considered but the joiners have responded as follows: "We have looked into various options for the door closures at Sandford lane which also include the standard Perkos and Perkomatics but we cant see how these are going to work with the anti-slam mechanism installed to the heads of the doors. These would be working against each other and we can see issues with either of them working if the door closures are to be fitted. I also think that the service user will struggle with the Perkos fitted and could see potential injury to himself if we use these." Any ideas for a solution please?
  27. Do I need emergency lighting in temporary offices Construction site if they are only occupied by the day?

    Mr

    Should a dormitory sleeping 54 students be fitted with a fire door or will a new plain internal door be sufficient. Thanks
