Intercoms & Access Control Systems

When choosing an electric gate system many people initially over look one crucial part. The access control will define how you and your family or co-workers interact with the gate system. Access control systems range from incredibly simple key fobs or card readers up to the elaborate networked systems and GSM (sim card) based units. However thanks to the size of the industry you can rest assured that whatever your particular specification there will be a product to suit. In this section we will look at some of the most popular access control solutions and discuss their strengths & weaknesses.

  • Basic systems access control.
  • Free exit and timer systems.
  • Wired intercoms.
  • Wireless short range intercoms
  • Wireless Long range intercoms

Basic system access control

For most people the reason to purchase a gate is to plug a hole in their perimeter security. Manual gates must either be manned in the case of a business or opened and closed manually. In most cases manual gates are simply left open and thus unable to fulfil their roll as a secure barrier. This is the purpose of automatic gate equipment, to ensure the gate stays closed to all except those with authorisation.

The simplest form of authorisation comes in the form of the humble remote control. Carry one with you on a key ring, press a button and the gate will open and auto close. Remote controls come with our kits and additional remotes can be purchased for friends and family.

Instead of remote controls business might prefer to use proximity cards. These systems work in a very similar way to remote control transmitters. Users need to pull up to a card reader and present their authorisation card to activate the gate. These systems are less convenient the remote control systems but the costs are much lower.

Some popular remote control and key fob systems include:

Basic Remote Transmitter
Key copy transmitter

The SUB44 is the classic remote control. It combines style with durability and will keep working for years. Customise your SUB44 to match your personality with 7 vibrant colour options. This transmitters is available in a high security rolling code or easy program copy version.

Simple Key Fob System for Business

Simple key fob, or proximity card systems are great for businesses as they can be scaled up more easily, giving your company an access control solution for a small price. These systems are best with up to 20 users, for large numbers we recommend the Intratone system.

Intratone GSM Card Reader

If you need to track who is entering and exiting your property or business premises, or if you need to add or remove users on a regular basis we recommend the Intratone range. Track remote control or proximity card use away from site.

Code pads are the final basic system we will cover here. A code pad allows you to have an endless number of users and several different access levels. For example you could have an all day access code and another which works from 9am – 5pm. Code pad entry systems work great on their own or when combined with more advanced intercom products. Here are some examples from our code pad range:

Basic Code Pad T1EM

Free exit and timer systems

The basic system described above can all be thought of as active systems where the user lets themselves into the gate. Free exit and timer systems differ because they are passive systems, opening the gate without the user needing to take any actions. Or conversely preventing the gate from opening in certain situations.

A free exit/ entry system uses a device like a photocell, vehicle loop detector or vehicle probe to open the gate whenever a vehicle approaches the detector. Free exit loops are the most common form of this system and the vehicle detector is normally placed inside the property to detect cars which are trying to leave, opening the gate for them.

Another solution if to fit a timer system. Time clocks, as they are commonly called, can be programmed to open or prevent the opening of a gate at particular hours of the day. Common uses include opening a factory gate at 8:30am and closing at 5:30pm with special access via code pads before and after, or disabling another from access control out side of working hours.

For example a 21PS code pad above could be combined with a Time Clock, one relay would work all day everyday and the code be given to management and security. The second relay would be linked with the Time Clock and would only work at certain times of day on certain days for the week. The same can be done to turn off free exit systems outside of business hours.

Time Clocks are ideals for sites which handle large traffic flows at certain times of day, passively allowing or denying entry. This system can be used alone or with other access control products.
