2.17 TX3 ADC Frequently Asked Questions
Q. What is the ADC feature?
A. The telephone access system is an auto-dialer that is connected to a public
telephone line. When a visitor enters a resident’s dial code number, the system
dials the resident’s home or cell telephone number (Note: as a security
precaution, the visitor cannot see the resident’s home or cell telephone number).
When the resident answers the call, he or she can press “9” (or whatever number
is selected as the Main Door DTMF) to unlock the main door and automatically
end the telephone call.
Q. Visitors cannot place calls to residents. Why?
A. If the problem is consistent with every resident, there may be a problem with
the telephone line. Check the telephone line with a regular telephone for a dial
tone. If the dial tone is not present contact your local telephone company. If the
problem is consistent for one resident only, the resident’s telephone number may
be programmed incorrectly. Check the configuration to confirm that the
resident’s telephone number and area code are entered correctly.
Q. Why does the system hang up as soon as a visitor begins to talk with a
resident?
A. The talk timer may be set for too short a duration. While in configuration
mode, check that the talk timer is set to more than 30 seconds (factory default is
60 seconds).
Q. Why can’t residents unlock the door/gate from their units by pressing
“9” on their telephones?
A. This may be caused by one of the following:
Incorrect Main Door DTMF setup.
Solution: While in configuration mode, check that the “Main Door” (DTMF) is
programmed to digit “9”.
Improper voltage on the door strike power supply.
Solution: Check for the correct voltage on the door strike power supply.
The door strike and system (main board) wires may be damaged or loose.
Solution: Check and verify that the door strike and system wires are intact.
Q. When a visitor places a call and begins to talk, he or she cannot hear the
resident. Why?
A. The speaker may not be working correctly. Unlock the entry panel and
perform a visual inspection of the speaker:
Look for loose wires as well as damaged components.
