| The Aiphone Access Sentry system is an audio door answering and door
release system designed for business use, but it works well in a house
too.
It is very simple to use. When a visitor presses the single button on
the door station, the master station receives a short tone and an LED
above one of the three corresponding station select buttons lights for
20 seconds. You then press the station select button and you can 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
door remotely.
The master station also has 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 selected 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 master 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 station can either be surface wall mounted, or desk
mounted. It wall mounts 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 a desk or wall mount master station,
two surface mount door stations, and an AC to DC transformer to power the system. This intercom requires 2 conductor,
non-twisted, 22AWG to 18AWG shielded cable between the door intercom and monitor.
A separate 2 Conductor, 22AWG, Shielded wire is used for the door
opening relay.
