Just so Mark doesnt get told off for advertising I'll mention the other poduct that's coming on to the market

www.smoclo.co.uk

Interesting, from the limited information currently on the site Smoclo looks like an internal version of the Dorgard.

Considering all the arguements on this site regarding Dorgard, which of the two devices (if any) seem the best?

It is hard to tell very much from the cartoon. If smoclo is a similar size to Dorgard then it must be fitted inside the door. It will be tough to ensure that the integrity of the door is not compromised.

Having just taken Holdfire through those tests at Chiltern Fire, I know how tough they are.

The cartoon seems to imply that the door can be left at any angle and will still close.

if this is true and it gets through testing to the releavant standards, then Smoclo will be better than Dorgard. I think it will have to go some to beat Holdfire though but then I'm biassed.

Smoclo replaces the headstop on the door frame and apart from the locating bracket which is mortices into the head of the door, the rest of the doors integrity is untouched. It's concealed (apart from a tendon that locates on the hinge edge of the door). The mechanism is triggered by a signal from the mains smoke detector (or power cut). The door can always be opened manually i.e. swing free and once the smoke detector is switched off SmoClo reverts to its normal swing free function.

Also BS EN 1634 to 30 mins
OK fo doors between 750mm and 900mm wide
Doors up for and including 50kg

SmoClo is mains operated, with optional battery back-up and closes the door from any angle.

For those who are interested SmoClo is on display at The Building Centre, Store Street - just off Tottenham Court Road. If anyone would like an introduction please call Royde & Tucker on T: 020 8801 7717 ask for Simon or Mike Stobart. At the moment RT are going through some market research with various sectors and finalising the launch plan with a view to launch the product in Jan 06.

From what I know there's nothing quite like it around - I'd love to hear any different tho.

P.s. Re: Details on the website - next job on the list

Interesting.

You will need to get it tested to BS EN 1155 if it is to be specifed.

In what ball park are you expecting the prices to be?

Will you still launch if ODPM decide to do away with closers in dwellings following the current consultation?

Simon Gardiner · « **Reply #35 on:** November 07, 2005, 09:42:22 AM »

We don't envisage requiring EN 1155 as it's not a hold open device.

The price we think will be around the £35 mark

Yes, probably with a greater focus on sheltered accommodation etc. We've already had interest from housebuilders in relation to the end users/clients being fed up with their doors slamming all the time - and only that reason, it's early days yet but all the feedback has been positive.

Markbr,

With the holdfire there's a wire going between the door and the frame would a conductor hinge be preferable?? They quite expensive tho I think?

Markbr · « **Reply #37 on:** November 07, 2005, 10:04:42 AM »

I was not aware such hinges existed. It might be a good option for new build. Do you know where they can be sourced?

With regard to EN1155, does Smoclo not allow the door to be left open in any position and then close in the event of fire?

Surley this is the same principle as a free-swing closer?

Simon Gardiner · « **Reply #38 on:** November 07, 2005, 11:37:03 AM »

Re: power transfer hinge see http://www.ratman.co.uk/H102-0.html

Yes that's exactly the mode of operation. At present we don't believe it's covered by the scope of EN1155 as it never holds the door open but we're seeking clarification form the appropriate bodies as to inclusion/exclusion. If it's found to be covered by 1155 it will of course be tested.

Markbr · « **Reply #39 on:** November 07, 2005, 12:04:27 PM »

Thank for the info on the hinge.

I have a copy of EN1155 and it covers free swing devices. If you don't think your device is covered by the standard then you may need to look into having one written around the product.

For a device that is being used for fire safety most companies will insist on a standard to prove the device operates correctly.

You might like to contact Dorgard who went through a lot of these loops.

Good luck, it sounds like a nice product.

Simon Gardiner · « **Reply #40 on:** November 07, 2005, 01:48:43 PM »

Thankyou for the info. We are at present drawing up a PAS for the unit.
Will let you know how it proceeds.

All the best
