By looping your home’s phone line through the system, a “call” button at the site of the gate rings the phone inside your home. At a business or gated community, the system itself would have its own phone line used to dial-in to various offices or homes.
Combined with an exit vehicle loop sensor, telephone entry allows easy access for visitors while maintaining a secure barrier for your home, neighborhood or business.
