A key phone system or key telephone system is a multi-line telephone system typically used in many offices for connecting internal users to each other as well as to the outside world. While there were traditional differences between a key phone system and a PBX (Private Branch Exchange), much of these distinctions are blurred. If there is any distinction, it probably lies in the capacity to handle calls and traffic, and other additional management capability.
An Intercom system, on the other hand, is used for connecting internal users only. A typical usage may be a door intercom unit installed outside the office connected to a handset that enable the user to screen and communicate with the visitor before releasing the door for the visitor to come in.
Both Key phone and Intercom Systems can be interfaced to our Card Access Systems to release doors and auto gates. If you have an existing system but you are not sure if it can be interfaced to a card access system, please contact us or email us.
