PhoneAire System Intercom
Operation:
A visitor desiring access will push the call button on the outside control station, causing a
special ring signal to be sent to the inside phone. Picking up the phone before 10 rings are
completed will establish intercom mode between the receiver and the control station. The
control station will respond with a GOOD BEEP. Hanging up the phone terminates intercom
mode. If the receiver phone is already ringing because of a call from the central office when
the call button is pressed a busy signal is sent to the control station speaker.
Call Waiting:
If the phone is already in use when the call button is pressed, a tone (similar to the central
office “call waiting tone”) will be heard, indicating the control station is calling. To place the
central office line on hold press the “#” key within 15 seconds of the first tone. The control
station will respond with a GOOD BEEP and establish intercom mode between the receiver
and the control station.
The “#” key can be used to switch back and forth between the central office and intercom
mode. However, the control station will only stay on hold for 15 seconds before it resets to
idle mode.
If the central office tries to ring the receiver while the system is in intercom mode, the same
call waiting tone will be heard. To switch to the incoming call press the “#” key.
Calling a Gate:
The receiver phone can call the receiver unit to establish data mode. To do this simply lift the
receiver and press “#1” within 15 seconds. The control station will respond with a GOOD
BEEP and establish data mode. If data mode is exited because of a call waiting switch, the
receiver will have to hang up and call the gate again to re-establish data. (The “#” key cannot
be used to get back to data mode if the receiver called the receiver unit.)
Intercom(Audio) Mode:
Once communication is established, the receiver phone is connected to the receiver unit in
data mode only. Commands to control the gate can be given from the receiver phone but
audio is not present. To establish audio between the phone and gate unit press “*3”.
Otherwise, to activate relay A press “*1” or “**”. To activate relay B press “*2”. A single beep
will be heard after the relay has been activated. To toggle the latch mode press the star key
followed by the pound key (“*#”). The control station will respond to the toggle-latch-mode
command with a single beep if the gate is now latched open, and a double beep if the gate is
now closed. To toggle the sleep mode press “*9”. The control station will respond to the
toggle-sleep-mode command with a single beep if the unit is now in sleep mode, and a double
beep if the unit is not in sleep mode. Since sleep mode and latch mode are mutually
exclusive, trying to activate one of those modes while the other is active will cause an ERROR
BEEP. To toggle the one-shot enable press “*5”. The control station will respond to the
toggle-one-shot-enable command with a single beep if the one-shot code in now enabled, and
a double beep if the one-shot code is now disabled. Hanging up the phone terminates
