Abstract
A communication device, system, and method configured for retrofitting into an existing dwelling unit intercom handset in an existing hard-wired building access system can be used to convert the existing building access system to one that is internet connected for remotely unlocking a door, gate, and/or similar. The communication device can be powered by drawing a small and controlled amount of current from the source that powers the unlock coil for the existing hard-wired building access system. The communication device can be configured to receive and transmit a ringer signal over the internet. The communication device can be configured to transmit an unlock signal to the lock deactivation module of the existing hard-wire building access system in response to information received from the internet and/or the ringer signal.
