Panel power issues
Concord 4 transformers
Concord 4 uses a 16.5 VAC transformer, (600-1023 or 600-1024 with power line
carrier). Concord 3 uses a 24 VAC transformer. Using a 24 VAC transformer on
Concord 4 damages the panel.
The panel does not power up and touchpads don’t display or respond.
• Verify that the panel transformer is plugged into an unswitched outlet.
• Check the AC circuit breaker to be sure the circuit is live.
• Check that the backup battery is installed correctly and the AC power
transformer is plugged in.
• Check for proper panel and transformer wiring.
• Measure the incoming AC voltage at panel terminals 1 and 2. It should read
about 16.5 VAC.
