The AT1001 Full Duplex Wireless Gate Intercom provides
crystal clear two-way audio communication with simultaneous talk and
listen, just like a telephone conversation. It has a direct line of
sight range of up to 4,000 feet.
Its full duplex speakerphone capability has background
noise immunity so when noisy trucks or other vehicles pull up to it,
clear voice communication can still take place.
The unit has dual built-in switch relays that can be
used for remotely controlling the gates or other devices from the inside
base station intercom. There is also an optional input for a Request-to-Exit
button or vehicle loop detector that can open the gate when activated.
Another input can be used for "auto calling" the inside station when a
vehicle loop detector or motion detector detects someone arriving at the
The AT1001 has excellent
interference immunity from other wireless devices. Its wire-free installation avoids costly
trenching and it is designed to easily utilize solar panels for power in
Multiple units can be used to comprise a single system,
which is ideal for large facilities.
A power supply is included with the inside base station,
and the outdoor callbox. Alternatively, the outdoor unit can be powered
by a 12 volt power source like a solar power system or vehicle power.
The "Call" Switch connections on the Outside unit
are used to connect a motion or photo beam sensor. When the sensor
is tripped, the unit automatically goes into transmit mode. A
ringing tone will sound on the Indoor unit(s) (and Outdoor) and then
whichever indoor unit answers the call, the call will become private
between those indoor and outdoor units.
The "Exit" Switch connections are used like the Call
switch, but the sensors are placed on the exit side of a door or
gate. When the sensor is tripped, the Inside unit will be alerted.
There are two relays or switches inside the Outdoor
unit that can be used to activate a gate or door opener, turn on a
light, ring a bell, or whatever you want. In Figure 5 you see to key
icons on the base station. These are used to activate the relay. If
you have multiple Outdoor units, only the relays on the unit calling
in are activated.
An Indoor unit can only place a call to one Outdoor
unit set to Access Point Number 1, but up to 9 Outdoor units can
call any number of Indoor units and the Indoor units can respond.
If the "Call" button is pressed during
communication, the unit will hang up. Otherwise, talk time is 4
minutes (fixed) after which the unit will hang up.
Up to 9 outdoor call-boxes can be on the same radio channel and
you can have as many indoor units as you wish on the same
channel. The indoor units DO NOT intercommunicate. Any indoor
unit that answers a call first is the only one communicating
with the outdoor callbox, no other indoor unit can be on that
conversation. However, there is one possibility if more than one
indoor unit answer a call at the exact same time then they're
able to talk/listen to the call-box that made the call.
