Induction Loops

Exit & Entry Induction Loops for Automatic Gates, Magnetic Sensors that Detect the Metal Mass of a Vehicle. When a Vehicle approaches the Gates or Barrier  It will be detected by the Induction Loops which will trigger the Gates or Barrier to open. Commonly used in conjunction with an Entry System such as an Intercom or Keypad. When someone has been allowed to enter via the Entry System they can leave via the Free Exit Loop. These Magnetic Sensors are some times used for Free Entry and Free Exit for example during office hours, the entry loop may then been switched off via a Timer Switch outside of those hours and the visitor would use an Intercom or Keypad to gain access.
