Automatic gates

[NozSpark]

I've been asked to add a timer to some automatic gates, on a residential park site, so that they open in the morning and then close in the evening.....

Don't know if it's possible at the moment, will have to get in touch with BFT Monday and see,,,,

but the question is

given recent events, would you do this if it was possible? and if so would you just install a timer or would you insist that you install a warning device to let people know the gate was opening?

also where does tha liability stop with gates, is it with the installer or the site operator/owner?

 

[matt.leung]

install a timer along with a flashing siren as a warning device. .....

^ what he sayds

depending on the existing control, there may already be an input for open & close. or it may just be a signal in 1 input to do opposite of what it is. in which case, you would need a sensor to detect if ifs open or shut, so it doesnt 'shut' instead of open

It's an Altair P panel..

there are 2 sets of inputs - one to open and one to close so I'd probably need a timeswitch and c/o relay... need to find out if it needs permanent signals or momentary and how they will affect keyfob operation...

BTW - Matt, what's a "flashing siren"

this panel also has programmable force limiting for the motors, so if set up right it should stop as soon as it touches something.

Like I said though.. the main question is...

given recent events, would you if you could??

 

[Andy™]

chances are it will be a momentary signal

you may be able to get a keyfob & receiver specifically for this gate, failing that, you could use one from an electric shutter and use that to trigger inputs. depending on the terminals of receiver, you may need to use relays on the outputs, or mod the PCB to make use of the relays on there for the signal

and providing the gate is safe and stops on impact, then yes. but would also have a siren & stobe activated 10-15 seconds (or whatever is needed) to give people enough warning to clear the gate before it closes

I have just had a look at the manual and its pretty basic in programming, I know some control panels have a double hold "stop" function but it has to be done from a keyfob or switch manually.

Any auto gates should really have beacons but the ones I have fitted I never bothered.

You can give the tech support a call and see what they would suggest.

I designed a wiring system for double opening sliding gates once, that was hard enough and is still used by the company when they install double sliders.

I like how you do those attachments

Thanks, got the manual already..

I was more after an answer to "would you if you could?" and "where does the liability stop if something were to happen?"

I think if I put a timer controled changeover relay across 17 (com), 20 & 21 then the gate will open & shut automatically.... I just wonder if having a permanent switch instead of momentary will affect the way the fobs work as they'll be needed "out of hours"

I know mate - I put it on there, so if anyone searched for them in the future, then they would find them, here.

Sorry Mate.

No need to apologise Admin...it's a great idea!

thanks admin for thinking of us then

I would suggest you ask for a test procedure for testing the inbuilt safety circuit on the gate control.

Then have the owner safety rep present while the test was being done.

Do this before and after any modification and get some sort of written prof of correct operation from the safety rep.

That just ain't going to happen...

what I will do is fill out the test/settings sheet (also testing with some fish scales [type of thing]) noting all settings and test results.. I will also be recommending that the gate is serviced/tested every 3 months (that ain't going to happen either!), but it should put any liability back onto them (at least after the 3 months)

Hopefully the system will have a safety stop /return if the gates encounter a resistance .

(As you say, with recent tragic event in mind) .

But as this is an unmanned operation , could the local scum create a resistance, gates return to the open position , scum wander in after dark and burgle flats .

 

[oldtimespark]

Only a suggestion as another way to cover yourself.

your way looks spot on also

There are no local scum... it's a "seaside resort" so the scum come in from Birmingham, Manchester, Liverpool etc ; ) ; )

No local scum , how wonderful , can you send estate agents details
