32 (42) Telephone Access System User Guide Version 1.1

Configuration

Check that the volume in the panel speaker is set properly, by entering the

configuration mode and reviewing the speaker volume setting.

If there are no loose wires and the volume in the panel speaker is set properly, then

adjust the potentiometer marked “SPEAKER” located on the back of the front

entry panel display (must open the front entry panel door).

Q. The LCD display has no display or the display has dark blocks on it.

Why?

A. There may be a problem with the contrast level. The potentiometer (contrast

control) is located on the back of the keypad/display board. Unlock the front door

and adjust the potentiometer for a darker or light contrast display.

Q. I misplaced the key for the telephone access system. How do I obtain a

replacement?

A. The Mircom key part number is LK-304. Contact your local distributor or

Mircom Head Office for a replacement.

Q. What happens when the visitor gets an answering machine when trying

to contact a resident?

A. The system will allow the visitor to leave a voice message on the answering

machine.

TX3 NSL 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 TX3-NSL-8M NSL Units (and TX3-8EC,

TX3-16EC NSL Expanders) in your electrical/telephone room intercept all

resident telephone lines coming into the building and communicate directly to

them.

Q. Why can’t residents unlock the door/gate by pressing the digit “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.
