Telephone entry intercoms are ideal for many different applications. Since telephone entry systems work through the phone lines, intercom wires do not need to be run. This makes this system ideal for a retrofit OR a new system. Ease of installation and ease of use makes Telephone Entry ideal for your next multi-unit application.

4. What is the difference between ‘Phone-Bill’ and ‘No Phone-Bill’ Telephone Entry Systems?
A ‘Phone-Bill’ (a.k.a. ‘dialer’) system is one in which the tenant is charged a surcharge by the phone company whenever a call is placed to the apartment through the lobby (entrance) or concierge panel. A ‘No Phone-Bill’ system has added electronics that eliminate the call surcharge. Most systems can be sold as a ‘Phone-Bill’ (‘dialer’) system the way they are and can be easily changed to the ‘No Phone-Bill’ type at any time.
