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 intercom.
The AT1007 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 remote applications.
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 keypad supports up to 502 user codes (1 Master User, 500 Users, 1 Temporary User). It has a code length of 3 to 8 digits and a tamper alarm for 4 incorrect code attempts
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 call-box, 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 callbox that made the call.
