	Telephone connected systems

	Audio entry panels connected via telephone lines for retrofit or difficult installations.

	Where the audio entry installation is to be carried out after the building is completed or as an additional facility for security or access control, it is often very expensive or difficult to install cables to all of the dwellings. A telephone based system overcomes this. A telephone line is installed adjacent to the Gate or Door and a specialist system is installed. This is pre-programmed with the telephone numbers of the occupants, and visitors use the entry panel exactly as a standard entry panel. The call is made directly to the resident's telephone and the resident can speak to the visitor and can press a button to release the gate or door to allow them in. Systems are available for up to 240 dwellings on a single panel!
