Tektone Apartment Intercom Troubleshooting

Step 1: Call Al (Intercom Guy) for technical support. 866-503-2298

Entire System Dead: If the power LED is not illuminated, check for 16 VAC at the transformer secondary and 120 VAC at the transformer primary. If the LED is illuminated, review the field wiring and perform a direct test using one of the apartment stations to eliminate field wiring.

No Talk: Check wiring to terminals 1 and 2, and check whether wiring to entrance panel speaker is shorted or open. Suite station can be swap tested with another working unit. No Listen Check wiring to terminals 1 and 3, or for short between terminals 1 and 2. Check to see if wiring to entrance panel speaker is shorted or open. Suite station can be swap tested with another working unit.

No Door Operation: Check wiring to door release for shorts and opens, or for defective door release. Confirm that shunts are properly set for door release type and that connections to appropriate output have been made. Check wiring to terminals 2 and 3, or 1 and E (depending upon suite station type).

No Call Tone: Check wiring to terminal Z or ZW to entrance panel, related entrance panel call buttons, and suite station X terminal. Suite station can be swap tested with another working unit.

Excessive Hum or Distortion: Check whether wiring is installed too close to electrical wiring or electrical devices; the amplifier installed too close to transformers or other electrical devices; twisted pair wiring not used as required; or amplifier voice volume set too high.

Radio Interference: Connect G terminal from amplifier to electrical ground. Note: This connection is not shown on the wiring diagram, since the situation is not always improved by adding it. If the problem persists, consult the factory or service representative.

Oscillation(feedback or howling): Reduce the voice volume until oscillation is eliminated. If oscillation stops when the call tone wire is removed from ZW, set entrance tone (SW3) to the OFF (left) position.
