|The Single Door Access System, 1 Door
Stations, 2 Masters is an audio door answering and door
release system designed for business use, but it works well in a house
It is very simple to use. When a visitor presses the single button on
the door station, the master stations receives a short tone. You can then
speak to the person at the door by pressing the Talk button on the
master station. The person at the door station speaks hands free. If you
have an optional electronic door release lock installed, you can also
press a door release button (key symbol) on the master to unlock the
The master stations also have an OFF button to put the unit into
standby mode to wait for the next call. This must be pressed at the end
of each call or you will be continuously monitor what’s happening around
the front door. You can also just press the Talk button to monitor
what’s happening at the front door without someone having to press the
button on the door station.
The voice volume on the masters is adjustable by a control on the
front of the master station. There is also a call tone volume control
hidden beneath an operator plate.
The master stations can either be surface wall mounted, or desk
mounted. They wall mount on a single-gang box or ring. The weather
resistant door station surface mounts on a standard single-gang box or
ring (or it could be mounted directly to the surface).
This is a kit that set includes two desk or wall mount master stations,
one surface mount door station, and two AC transformers to power the system. This intercom requires 2 conductor shielded cable between the door intercom and monitor.
You cannot make a call from master to master station with this system. It only communicates from master to door station.
