Interlogix Concord - Power troubleshooting
If keypad trouble lights are seen when information is requested or programming is sent to the panel, there is likely a power issue with the module or panel. Inconsistent response to programming commands can also indicate a power issue with the module or panel.
Panel power
- Verify the panel transformer is plugged into an unswitched outlet.
- Check the AC circuit breaker to verify the circuit is live.
- Verify that the backup battery is installed correctly, and the AC power transformer is plugged in.
- Verify the panel and transformer are wired properly. For information about wiring, see Interlogix Concord Installation Guide - Panel.
- Ensure the wire from the panel to the transformer is a 2-conductor, 18 or 22 gauge, and no more than 25 feet long.
- Verify the incoming AC voltage at panel terminals 1 and 2. It should read about 16.5 VAC. For more information about measuring voltage, see What are the power requirements for a Interlogix Concord?.
- If there is no incoming AC voltage at panel terminals 1 and 2:
- Unplug the AC power transformer.
- Disconnect the wires from the transformer and the panel.
- Check the transformer to panel wire for short or open circuits.
- Plug in the transformer, and check for 16.5 VAC at the transformer unconnected terminals. If the voltmeter reads zero (0) volts, replace the transformer.
- If there is no incoming AC voltage at panel terminals 1 and 2:
- Verify the battery voltage is 11.75-13.8 VDC between the backup battery spade lugs. If the battery voltage is not within this range, replace the battery.
Module power
- Verify the wire length and gauge used for the Alarm.com module.
- For 22 gauge, 40 feet (12.2 meters) is the maximum distance.
- For 18 gauge, 90 feet (27.4 meters) is the maximum distance.
- If there is a missing or empty equipment list on Alarm.com but the panel is communicating, check what devices the panel has connected to it besides one keypad and the module.
- If there is a large number of zones, zone expanders, and other devices, the panel requires additional power supplies. Depending on how many power supplies are currently being used, it is suggested to increase the power supplies to the additional devices.
