Electric Gate - have it open ready as you arrive

[buzzer123]

Hello all - I would really appreciate some advice please.
I am conducting the groundworks to install a 6m opening "Hi Motion" sliding cantilever electric gate (9m length in total).
I have to commission an electrician to make it all happen but the client has asked for a cabled means to have the gate open before they arrive at the gate.
I am installing a electricity kiosk within their land at the top of the lane (and the gate is 250m down the road - which is heavily wooded so wireless could be an issue)

What I was thinking was to install a sensor at the top of the hill by the kiosk so that as the client approaches by car they can slow and bleep the sensor and then by the time they get down the lane to the gate it will hopefully be open ready for access with no waiting for the gate to get out of the way.

Please advise what you all think would be the best solution to achieve this (p.s I will have an open trench to take power down the hill to the gate from the kiosk so could install a further cable etc but would it work over that kind of distance - approx. 250m)

A phone app would also not work as reception onsite is terrible.

Thank you all in advance for all your help

Welcome to the forum mate.
Cable can work over any distance you want. We have power cables that run over many miles along pylons. It all depends on how much power is needed at the destination and how much money the customer is willing to spend.
How many amps goes the gate need?
So the distance from the kiosk to the gate is 250m. Where does the kiosk get its power from? How far away is this?

Hi - thank you for your reply, The kiosk is 2m from the power pole whereon uk power networks guarantee +/- 6% of 100 amp 3 phase.
The calcs have been done I think with regards to guaranteeing power down to the site (which includes the gate) but the obstacle to overcome is getting a sensor (or another means? - any ideas) installed 250m from the gate so that the client can zap it on his approach to the gate and then as he drives down the lane the gate would be opening and he could drive straight in without waiting.
Thanks for any suggestions

Have you had a search of the forum?
I found this but I'm sure there are more sensors out there that could do the job for you.

Cat5/6 is good for 100m without a booster, how about an ANPR camera 100m away from the gate?

What about just using gate photocells at some point along the lane?

What about just using gate photocells at some point along the lane?

Would they be able to discriminate between an authorised vehicle versus any vehicle that the gate should not open for?

 

[ruston]

A remote control sapper for authorised persons could be considered with the receiver at the appropriate distance to the speed and time required. All other traffic would have to use the intercom usually provided near the gate. How else would it be secure?

Have a look at these devices.

Having slept on this one, would the much simpler solution for anyone with a 250m drive, be to have one's butler on hand to open the gate and tip his hat, as one's chauffeur drives the limousine through? No electrics or electronics required.

Thank you for all your suggestions guys - really appreciated.

Ha Ha - Thanks tony. No the client is a hippy !! (think catweasel but a really nice chap who has become my friend over the years) He lives off grid in a cabin with no power - compost loo - water from bore hole etc

He has come into some money (deceased relative I assume) and is now going for gold getting power to his house and an an electric gate as well as a septic tank to bring himself up to 21st century living standards.

I am doing all the groud prep work and want to get it good for him as he does not really have any idea.

This is the reason I want to know roughly what Im talking about before I talk to local electricians so that I do not appear totally stupid

He does not have lots of land Tony (postage sized stamp) and lives rurally next to a local estates wood who have now kindly given him permission to bring power cable down through their wood.

So I was thinking a push button in the car with private radio code or something so only the customer can open the gate as he drives down the public lane towards his entrance.....the electric gate is going to take six seconds to open from once its pressed so I thought it could be open ready for him - at his request Batman style

Any other ideas gratefully received.

Most gates will come with this facility , although I am not sure of the range on a standard remote.

The gate open method is basically a switch that requires 2 wires . So I would install a reciever at the point on the drive where you would like gate to start opening and run a 4 core swa from this point to the gate controller (2 cables for the switch and 2 spare for future use ) im not sure on the cable size without calculating but I would of thought 2.5mm would do the trick . The receiver can be operated by a key phob.

Thank you Flanders - will look into that

Ok but Just speak to your electrian first to check cable size

You/the client are going to need a certified gate installer. There are a lot of safety features to build in and the installer will have a number of solutions for the customer’s requirements.

Ensuring powered doors and gates are safe - HSE

www.hse.gov.uk

The last one I did the Sparks for had a nice app on a mobile phone, so the client could open the gates as he turned off the motorway.

Really, find a gate installer and give himself the problem.

For unattended operation , you have to think
"Hapless entitled child ,climbing on gate -gets caught in workings - Compo case "
--expensive sensors- !
(or a Butler with CCTV)

 

[jackhammerJIM]

Sim card and relay combination would eliminate a long run of cable . Dial the number to open the gate .

Re: Taylortwocities #17: very good advice about safe electric gates which should not be ignored.

By the by, I spent an enjoyable couple of days restoring some electric gates to wireless remote, keypad, fob and hall intercom button control after the gates had been necessarily modified to avoid crush and car damage but alas left with some difficult to find wiring faults - the gates and their control had not been tested before modifications so the company argued they were original faults. The safety modifications were done to prevent another episode of expensive damage to cars and people which remained in the gates' swept area.

Top tip - go for wireless/wifi interconnections to avoid wiring runs to sensors. eg:

https://www.theelectricgateshop.co.uk/search.php?searchword=wireless&go.x=20&go.y=24

Good gate controllers, in this case a CBME one, already allow radio control with the addition of a small circuit board and internal aerial.
