FlashGuard 2000B Troubleshooting Guide

Section 10 All lights are in sync, but there is a double-flash, or flashing faster than 40 flashes per minute (fpm).

Possible Cause: More than one sync monitor board is set as master.

Diagnostic Test: Inspect the DIP switches on each sync monitor board. In the master power supply, DIP switch S1-4 should be set to “OFF,” which is the master position. In all the other power supplies, this switch 4 should be set to “ON,” which is the slave position

Corrective Action: Reconfigure sync monitor boards. Refer to the manual for correct positions.

Section 11 Master unit switches to night mode at night, but slave units remain in day mode.

Possible Cause: Interconnecting wire between master and slave power supplies missing.

Diagnostic Test: Inspect wiring between power supplies. TB1 position 1 should be daisy- chained between each power supply, per the installation wiring diagram for multiple units. Note: Do not interconnect TB1-2 between power supplies.

Corrective Action: Install interconnecting wiring.
