Radio control transmitters
The most commonly used opening devices are radio control transmitters, with handsets that can be carried in your pocket or on your car key ring. Three and four button units are available that allow you to operate your gates and garage doors with one transmitter.

SEA can supply two main types of transmitters:

The Smart range - using either a unique fixed code or dip switch coding.

The Head transmitter - a high security rolling code system with slightly increased radio range and unbreakable coding system; for the ultimate in gate security.

Push Buttons, Metal detectors, and Infra red beams - Lots of different methods can be used to provide free entry and exit to any gate or barrier system. They can all be controlled via time clocks or switches, providing different control packages to suit each individual customer security requirements. Systems are often fitted with metal detector free entry and exit during the day, switching to security intercom access for visitors after 6 pm.

Key switches, code pads, card readers and finger print recognition - Security of access to a site is often more important than convenience; SEA offer compatible equipment from the simple key switch to proximity card readers, or even finger print recognition. An SEA proximity card reader and radio control system allows control for up to 500 individual users, with a simple deletion and insertion technique. If computer controlled or fully networked systems are required, we stock both Videx and Bewator systems. The SEA control panel can interface with most other manufacturers' security equipment.
