The Universal Doorphone is designed for applications where calling access is essential yet installing a phone may be impractical. This device connects a telephone extension to the system, allowing visitors to call a pre-programmed extension by simply pressing the call button on the remote stainless steel speaker panel.
Features include high-quality, vandal and weather-resistant stainless steel housing, an auto answer option, and a telephone-powered line.
It comes with a 30-second call timeout limit and adjustable microphone and speaker volume, all housed in a weather and temperature resistant case. The call timer duration can be adjusted from 15 seconds to 2 minutes.
