Gates for Gated Communities and Housing Complex's
Fully automated Security Gate with remote control, key tags or mobile phones used by residents to get in, an Intercom for visitors to get in and in ground detectors for all vehicles getting out can improve the security and quality of life for those living in a community of homes.
Things to consider with gates for a Gated Community:
- Number of users
- Is a swing or sliding gate more suitable?
- Placement of letter boxes, intercom and gates to avoid traffic congestion during peak times.
- Safety of all users including: residents, visitors and the general public.
- Security - preventing cars sneaking in behind others and controlling pedestrians.
- What happens if the power goes out?
- How will visitors get in or out?
- Is it necessity to lock the gate electrically?
Number of Users
Generally automatic gate motors rated for residential use are suitable only for up to four house holds sharing one gate. Any more than this and a higher rated motor is recommended that can work continuously without over heating and do so for a number of years without wearing out. It has been found that commercially rated motors will last significantly longer, are much more reliable and can take the knocks if someone nudges the gate with their car or someone tries to force the gate.
Is a Swing or Sliding Gate more Suitable?
Sliding gates are more suitable than a swing gate when: a driveway slopes up from the road or there isn't room for a gate to swing but sliding gates do need space to open into.
Residents will tend to want to check their letter box while driving in or out to save having to walk so need some were to park their car for 5 minutes that is out of the way of other vehicles wanting to use the gate. Also the Postie needs access to the letter boxes and will need a safe area out of the way of other vehicles to deliver the mail.
An intercom should be placed away from other vehicles using the gate so if a visitor has stopped to use the intercom and an authorised user wishes to get in they don't get stuck behind the visitor if they may not be able to gain access.
Separate Entry and Exit Gates
To allow higher volumes of traffic to flow more smoothly a separate entry and exit gate is recommended, particularly if an RFID card system in use because the card reader is best located on the right hand side of a residents vehicle so they can reach it from their drivers window. If a 2 way gate is used vehicles tend to move towards the centre blocking any vehicles wanting to exit and if an RFID card reader is used incoming vehicles will need to enter the outgoing lane to use a card reader.
It is also more desirable to have the outgoing gate opening outwards so vehicles won't have the gate opening towards them.
An in ground vehicle loop detector also works more effectively with a separate EXIT gate because then incoming vehicles are not detected so the gate will close more quickly reducing the change of vehicles following another in.
What happens if there is a power failure? Ideally the gate will continue working regardless, even with a lot of users, which requires a continuously rated battery back up system
Residents Access Control
Residents may have:
- Hand held keyring sized remote controls allow each Resident to open the gate. These are best used with a management system that assigns remote controls to users individually so they can easily be removed from the system even if lost or stolen without having to reprogram the entire system.
- An RFID key card or tag touched on a reader will open a front entry gate. These are a more economic alternative to remote controls with a management system for assigning cards or tags to users individually.
- GSM/3G Access Controls use Mobile Phones as remote controls by registering users mobile numbers into the system and the user speed dialling a pre-set number.
- A Digital Keypad can also be used where everyone can be issued a separate pin number although these tend to be vulnerable to people sharing numbers so isn't the highest form of security.
Visitors Access control and monitoring who's coming and going.
Visitors, delivery men and tradesmen require an intercom system to each home. The intercom at the gate either has a button for each home or a digital keypad so the home number can be dialled in. Some systems have an alphanumerical display where an occupants name can be searched for.
A Video Surveillance system at the gate is also very handy for users to screen visitors giving them the choice of whether to let a visitor know if they are available or not. A video surveillance system can also be combined with a 24 hour digital video recorder system to keep track of who is coming and going and capturing events such as someone driving into the gate or activities of vandals
Does a Gate need an electric lock?
Sliding Gate motors lock the gate too so nothing further is needed.
Swing gate motors for Gated Communities do need an electric lock because the likely hood that someone will be pushing on the gate to try and get in is very high. Magnetic locks are recommended for Gated Communities and are best used to lock a single gate to a receiving post. If you have a double swing gate then a powered drop bolt is necessary to lock both gates to the ground, this does require a hard stop in the middle of the driveway.
You may also have a Small Side Pedestrian Gate that can be tied in with the automatic gate system. Magnetic locks are also the most reliable solution for electrically locking Pedestrian gates in gated communities with a self closer to prevent it slamming in the wind.
