Hi Jeremy
I hope that you are well.
Once again thank-you very much for your
help and support, I really appreciate it. It makes me feel a lot more
confident about responding the specification that I have been provided with.
Kind Regards
Ann Collins

Hi Ann
General:
Firstly and probably most
importantly, buying cheap automatic door openers is a false economy. Secondly
and in relation to this, budgetary allowances for ongoing maintenance/service
support. Thirdly make budgetary allowance for power backup in case of mains
failure – identify the safety critical doorways (which in reality is probably
all of them). Fourthly make sure that the doors have appropriate safety
features installed. If you can afford them, you want openers that allow the
door to be pushed/pulled/crashed without ‘throwing a wobbly’; these systems are
generally door closers augmented with motors and tend to be at the expensive
end of the market, but are worth investing in if you can.
External doors:
It sounds like you are
talking about a block of flats, so make sure that your communal door entry
system can be interfaced to from each flat independently. Most systems don’t
allow this but some provide a proprietary interface board for such purposes.
The communal entrance is normally the one that is forgotten about, regarding
the special needs aspects, until it’s too late. This might prove the trickiest
bit to get right. Make sure you have a spec for it that also meets the needs of
the potential clients. You probably need a system that can manage visitors from
the outside and internal visitors as well, so it needs thinking through.
Internal doors:
Definitely a good idea to
have IR receivers connected to each door so that any EC controller can access
them. RF has a place but be careful that you don’t end up with a system that
requires the client to carry a hatful of fobs (most openers can handle having
both an IR and RF interface attached). Also think about whether you want
automatic opening and if so how; PIR sensors can be annoying if not set up
properly; IR beams can be good if the design suits; and, pressure mats may be
an option. I would also suggest that it is important to have an easy method of
toggling automatic opening mode.
Above all, make sure that
the architect has good experience in this area of design and if not, make sure
he gets good, independent advice. Hope this helps
Cheers
Jeremy

Subject: Door Operators
Dear All
I was wondering if anyone had any advice / guidance /
checklist around specifications for door operators that they would be prepared
to share with me.
I am working on a New Build project which is designed to
accommodate people with both a learning and physical disability and are looking
to automate both the front door to the property and internal flat doors.
We are keen to ensure that any system we install is robust enough for its
intended use and has the capacity to interface with environmental control
systems and remote fob activation.
I would be really grateful for any advice or guidance or
recommendations that you could give me.
Kind Regards
