Repairing ADT Security System Panels

ADT has made many versions of its security system panels over the years. Our technicians check the model and serial number, review known issues for that model family and test before replacing parts, so you only pay for what is actually needed.

How we repair your ADT Security System Panel

A security system panel is the control unit and keypad for a home alarm that monitors door, window and motion sensors and reports alarms to a monitoring center. A security system panel uses sensors, a power source of batteries or low-voltage wiring, a control panel or app, and often a wireless connection. A technician checks power, wiring and transformers, sensors and network connections.

Diagnosis

Common ADT Security System Panel problems we fix

What usually causes each symptom, and what our technician checks to confirm it.

Communication failure with the monitoring center

Likely causes
A disconnected phone line, a failed cellular communicator, or internet service changes.
What our technician checks
The communicator signal and connection are tested and a test signal is sent to the center.

False alarms

Likely causes
Motion sensors seeing pets or heat sources, loose door contacts, or low sensor batteries.

Alarm history is reviewed and the triggering sensors are tested and adjusted.

Siren not sounding

Likely causes
A failed siren, a broken siren wire or a blown fuse on the panel output.
What our technician checks
Siren output voltage and wiring are tested.

Keypad blank or unresponsive

Likely causes
A failed keypad, a broken keypad data wire, or a power loss at the panel.
What our technician checks
Power and data lines to the keypad are tested.

Low battery or AC power trouble

Likely causes
An aging backup battery in the panel, a tripped breaker, or a transformer unplugged.
What our technician checks
Battery voltage under load and transformer output are measured.

Keypad shows a zone fault and will not arm

Likely causes
A door or window left open, a misaligned contact magnet, a broken sensor wire, or a dead wireless sensor battery.
What our technician checks
The technician checks the zone, tests the sensor and measures zone resistance or wireless signal.
Before you call

Quick checks you can do safely

  • Make sure all doors and windows are fully closed.
  • Read the trouble message on the keypad and note any zone number.
  • Replace batteries in any wireless sensors that report low battery.
  • Check that the panel transformer is plugged in and the outlet has power.
  • Call the monitoring center to put the account on test before working on the system.
