Frequently Asked Questions
Q. What is the NSL feature?
A. The NSL (No Subscriber Line) operation does not use a dedicated public subscribed telephone
line; rather the 2008M NSL Units (and 2008/16 NSL Expanders) in your electrical/telephone room
intercept all tenant telephone lines coming into the building and communicate directly to them.
Q. Why do visitors get a “system busy” message when they call tenants?
A. The lobby unit may not be communicating with the 2008M Relay Control Panel. Check the
programming mode to ensure that the NSL ID is programmed to the same address number as the
2008M Relay Cabinet.
Q. Why can’t tenants unlock the door/gate by pressing the digit “9”on their phones?
A. This may be caused by one of the following:
• Incorrect Main Door DTMF setup.
Solution: While in programming 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. Why does the system hang up as soon as a visitor begins to communicate with a
tenant?
A. This may be caused by one of the following:
• The online timer may be set for too short a duration. While in programming mode, check that
the online timer is set to more than 30 seconds (factory default is set to 60 seconds).
• If the tenant has a high speed Internet connection, there may be an ADSL conflict. To solve this
problem, the system requires an ADSL -100 filter that will mount in the NSL cabinet (2008M
relay control panel).
Q. Why won’t the system accept a language change from English to either Spanish or
French?
A. The system must be reset for language changes to take effect. Reset the system after you make
a language change. There are two ways to reset the system:
• Enter the programming mode and scroll down the menu option list to locate “system reset”.
Press “0” to reset the system.
• Turn the on/off switch (located at the bottom of the circuit board) to the OFF position and keep
it off for approximately ten seconds before powering up again.
Q. When a visitor places a call and begins to talk, he or she cannot hear the tenant.
Why?
A. The speaker may not be working correctly. Unlock the panel and perform a visual inspection of
the speaker:
• Look for loose wires or loose solders as well as damaged components.
• Check that the volume in the panel speaker is set properly. VR4 (volume control) is the
adjustment potentiometer for the standard board and VR2 is the adjustment potentionmeter for
the slim line board; both are located at the bottom of the board. Adjust the potentionmeter
clockwise to increase the volume.
