  1. There is the old fashioned method of interlinking via cable using standard interlink smoke alarms. I doubt they transmit continuously as the batteries wouldn't last too long but the manufacturer will know the full info - if it's any use to you they transmit on 868MHz

  2. The old answer was the last flight of external escape stairs was cantilevered and only lowered to ground when used:

    You need to consult your Approved Inspector or Local Authority Building Control immediately with your issue - they may not accept certain solutions, the fold out ladder is unlikely to comply, chutes have been accepted but normally in very specific circumstances and not for the public.

    You may find it more appropriate to seek a fire engineered solution to avoid the need for the alternative route - bigger projects than yours have avoided the need for entire stairs by use of domestic sprinklers and a enhanced smoke control solution.

  3. No, any fire alarm system in a place of work must have two power supplies to meet the Health & Safety (Safety Signs & Signals) Regulations, which usually means mains and battery. You would need all alarms in the relevant area to sound, not just one in a local area.

    This assumes the bays are not open air and the system isn't a proper BS5839-1 wireless fire alarm system where individual devices have dual battery power.

  4. Yes it could affect insurance and could be a criminal offence without needing for a fire to even occur as there only needs to be the potential risk to life rather than it being realised by an incident.

    I'd get a new FRA though by someone that knows what they are doing and the specific standards for domestic premises- a common areas only system would be inadequate as it would only sound when the escape was already affected by fire and would draw people from the relative safety of their flat into the smoke & heat filled stair, plus wouldn't penetrate the rooms of the flats with enough audibility to wake occupiers. Also, depending on the nature of the construction of the building and it's conversion it may not need the alarm at all.

  5. The single light on a standard EL fitting (green or if a very old unit red) shows the mains supply to the fitting is on and the batteries should be charging, if the unit is still showing it's LED it would imply it's mains feed is still on and the light is fed off a different circuit to the one on the test switch you used......or that something else is wrong.

    If it has more than one LED then it's likely to be a self testing unit and could have a meaning specific to the fitting. 

  6. They need to be blue as a mandatory type sign in order to satisfy Regulation 4(4) and (5) of the Health & Safety (Safety Signs & Signals) Regulations 1996 as defined in SCHEDULE 1 PART 1 "Minimum requirements concerning safety signs and signals at work"

    It's a moot point as to whether it makes a practical difference as these signs don't include a specific pictogram, older buildings sometimes have the previous style of fire door keep shut sign using a red diamond on white with text in the middle, I certainly don't loose sleep over it - it's better than nothing - so would consider it a low priority compared to other signage issues (including no sign at all).

  7. You would expect to find a fire detection & warning system which, depending on how the premises are viewed (HMO, educational sleeping risk, etc), would be a commercial grade system of call points, sounders and detectors linked to a control panel or at the very least interlinked mains smoke & heat alarms, with detection to at least the stair and landings and usually the kitchen and other rooms as well.

    The stair would usually need to be protected with fire resisting construction & fire doors, exceptionally good fitting normal doors are accepted depending on how the premises are classified.

    Basically the premises should be set up so that a fire is detected and kept out of the stair with more than sufficient time to escape before the stair itself is compromised.

    If you have concerns then depending on the status of the premises either the fire service or local authority housing department are the enforcing authority.

  8. You are, of course, not obliged to follow a particular assessors advice and can seek alternative advice as the legislation is functional and not specific to a particular solution.

    In addition to chairs there are evacuation mats, managed use of lifts, delayed self evacuation and many more options depending on the individuals needs.

    You don't mention a lift - do you have one?

  9. If your CO alarm goes off for for than just a very brief period realistically you should follow the official advice:

    If your carbon monoxide alarm sounds or you suspect a leak:

    • Stop using all appliances, switch them off, and open doors and windows to ventilate the property
    • Evacuate the property immediately; stay calm and avoid raising your heart rate  
    • Call the Gas Emergency number on 0800 111 999 to report the incident, or the Health and Safety Executive (HSE) Gas Safety Advice Line on 0800 300 363
    • Don't go back into the property; wait for advice from the emergency services
    • Seek immediate medical help; you may not realise you've been affected by the carbon monoxide and going outside into fresh air won't treat any exposure by itself

    I live in a Victorian house converted in to four flats. I am the on the top (2nd floor). My flat entrance door opens to stairs down to the communal hall way which leads to the main entrance door. I am at the top so no one would pass my flat in case of a fire. The Fire Risk Assessment recommended each flat installing a self-closing device as a priority. I have done this to conforming standards.

    The second comment was 'intumescing & smoke seals are recommended as part of an improvement plan''.

    Specifically related to the intumescing & smoke seals, do I legally have to do this or is this merely a recommendation? 

    Any advice or guidance docs would be much appreciate.

    Andy

    If the conversion was Building Regs compliant and is a 'Stay Put' building then ultimately they should be present, but based on the size of premises they are not an immediate requirement (based on the LGA Guide covering fire safety in purpose built flats)

    If a non compliant conversion and thus using full evacuation then under the LACORS guide they should be FD30S doors with strips & smoke seals

    I have a 2 bed flat on the 2nd (top) floor of a block of flats that I rent out.

    The managing agent has had a fire risk assessment completed and I need to change my door to a FD30 with self closing, 3 hinges and appropriate seals. I am happy with all of that but they have also said “smoke alarms have to be hard wired” if you are a landlord but not if you are a private owner.

    I consider myself to be very responsible. I have 2 ceiling smoke alarms, a carbon monoxide alarm and a fire blanket in the kitchen - all checked every 6 months.

    I rang my local fire station and told them about the “hard wired” smoke alarms and they said it was not a legal requirement - so do I have to do it?

    It's not strictly a requirement in existing rented premises, the legislation (seperate to that within the remit of the FRA) compelling private landlords to provide smoke alarms is vague enough to make the use of Grade F (battery only) smoke alarms legal. If you were to carry out a full rewire then under Building Regulations you would need combined mains & battery alarms (Grade D1 if rented, D2 if owner occupied)

    The risk assessment is for legislation that doesn't even apply inside your flat beyond measures protecting the common areas and other occupiers (i.e. the front door and in substandard construction buildings parts of a communal fire alarm system) 

  12. It should have a manual valve in all cases and if provided with a fixed suppression system and automatic valve as well that operates if the system is activated.

    Retrospective provision of automatic release on general alarm isn't required unless insurers or risk assessments indicate.

    Some buildings will have linked the main gas intake valve to the alarm instead so all gas equipment shuts down not just the kitchens
