Clock Troubleshooting
Secondary Clocks Not Synchronized
1. Make certain the AllSync IQ master is running the correct clock code.
2. If the AllSync IQ master time was recently changed, allow up to 24 hours for secondary clocks to re-synchronize to the
AllSync IQ master.
3. Make sure there is sufficient voltage across each secondary clock.
4. If fewer than 25 AllSync secondary clocks are connected to the system controller, the secondary clocks might not
recognize the correction from the AllSync IQ master. Connect all intended clocks to allow time for normal AllSync IQ master
correction. If secondary clocks still have not corrected, you may need additional hardware. Contact American Time Technical
Support for information on adding a Resistor Pack (Part #H001941) to your system.
If the problem cannot be resolved after following these steps, please call Technical Support at American Time at 800-
328-8996.
