  • Remove all the telephone units connected to the single Tip and Ring Line:
    • Problem is resolved: verify what unit is overloading the system and replace; OR
    • Ensure that a maximum of 4 Telephone Access is connected to one Tip and Ring Line.

• Tip and Ring Bi-directional signalling is not differential or in-ground current noise issue:
  • Install a 0.1 Micro farad capacitor in series to the Tip. Then line test:
    • If the signal/noise improves then Line is unbalance. Request Line Card change-out; OR
  • Disconnect Tip and Ring from the module. Measure the voltage ( potential) between Tip and Chassis ground. If voltage exceeds 2.0-2.5 volts:
    • then run a 10AWG/Stranded cable from the telephone access unit to the communication demarcation point to ensure voltage drops to approximately 0 potential difference; OR

Change out the power supply. Ensure the power supply ground is connected to the power ground and not the communication ground.

• AM carrier is coupling on the ground lines ( Tip and Ground) and then demodulated via the telephone bridge . The following should occur:
  • Verify that board has the current Board revision ( Mircom installed a notch filter removing the prominent carrier wave). If the board is not of current Revision, change out the board; or
  • Install an isolation telephone line transformer between the board’s ground and telephone line. Ensure that no other grounds are connected to the board and that the casing is not connected the Telephone’s metal casing; or

Use a analog/VOIP service to service the lines through the internet instead of analog lines.

• TXTOUCH screen is not receiving enough power caused by the following:
  • The voltage, at the TXTOUCH input is below voltage. Increase the voltage by adjusting the adjustable power supply to the required 24 VDC voltage;
  • The 120VAC power feed to the Power module is reversed. Change out the power module and ensure that that the hot of 120VAC is properly tide the right side; and

TXTOUCH’s power module is damaged from generator testing. Replace the power module and protect the TXTOUCH by installing a UPS.

• A solid ground point is a 6 AWG stranded ground wire feeding a room and coming from the building’s bond point ( Building bond- a point where all building corners has the same equipotential point)

• There is a short between the A+ and the B- connection to the RS485;
  • Check the lines;
• Camera supply ( on board) is deregulating the 5V DC DC Converter. Remove the camera supply from the system and restart system, including the board. Telephone module is over loading the 5v DC DC supply:
  • Replace the main board;
• TXTOUCH system is not UPS power protected from the Building’s unregulated power supply;
  • Change telephony board, verify if database is conserved and install a UPS;

Yes, it is important and required as per NEC as well as FCC regulations. The telephone access unit should and must be grounded to the same communication bond point as the Building’s communication equipment. A confirmatory test to determine if the communication bond is the same ground point as the telephone ground is by measuring the voltage ( in ONHK mode)between the Tip and the equipment ground. The potential between the two points should be as low as possible ( 0>x<275-300mV).

No, the Tip and Ring Telephone lines does not matter how you connect then to the line connector. Tip/Ring for connector one and Ring/Tip for connector two.

Displays can become blank because of poor ground issues. Make sure the TX3 telephone entry panel’s chassis is connected to a GOOD ground point (<50 ohms) and power cycle the panel. The display should come back.

• Door strike power supply gets connected to the “Door Supply” terminal and the AC/DC door strike gets connected to “AC Door” or “DC Door”. Ensure that you use a separate power supply for powering the door strike.

• If you are controlling the front main entrance with a Non Mircom access control system, only tie a two wire connection for activating the front main door. The door strike power supply will be supplied by the access control system.

• If you are using a Mircom’s access control system, then no wires are needed to activate the door strike. For more information please read the instruction Manual.

Once you determine the faulty panel, upgrade the firmware to the panel. Use direct USB connection to the panel for firmware upgrade after recycling the power. Then put the panel back online. Ensure that the panel is properly grounded.

The output dry contact can wear with time. Tx3-series Dry SPDT UL operation zones are : 0.5Amp@120VAC to 5Amp@30Vdc and have Mean Time Between Failure of 1,800 cycles per hour or a total of 50,000 operations in one life time (100days @ 500 door opens per day). A typical SPDT relay wear points is the contact between the contact or continuity between “ common” and “NO” or “NC” . After a while, in high traffic zones the resistance exceeds the input sensing of the device. From that, all that is required is to change dry-SPDT relay point for immediate corrective action. Other factors associated to dry-SPDT relay wear is high current feeds. In some cases, it’s the high inductive rush current that causes dry-SPDT relay failure. In this case, examination of the inrush current should be measured if fast relay wear has been noted.

Yes, Absolutely, the Snubber circuit eliminates abnormal and harmful reactive current surges through wet and output relays. Without Snubber circuits, relays will not or eventually fail after experiencing relay jitter ( for dry relays) and/or raised ground voltage levels ( through wet relays causing abnormal electronic operational failures). These reactive effects increases with increasing magnetic flux ( the core holding strength to MAGLOCK systems).

For the TX3 series card access panels you have 2 powered/wet outputs #7 and #8 that supplies a 12Vdc ( solid-state) 1 amp-shared for door strikes and maglocks, within fire code requirements.

No, unfortunately, it is the installer’s responsibility to conduct a respectable site feasibility study, with appropriate product recommendations, based on the study, to determine what is required to ensure system stability

Their should be a 24VDc, 5 AMP power supply used to power 4-to-5 access control modules.

All TX3 telephone entry/per  unit and access control/ per unit are running off a (PS-4P) 40 VAC power supply.

We have a three year warranty from the date of purchase. However, if the cause of the damage was caused by feasibility site neglect then warranty can be void.
