Wiring for synchronized strobes and horns.
Using this method you may:
Use the Potter Electric GTSM synchronization protocol to provide synchronization of temporal 3 and temporal 4 tones and mute the horn, if required.

NOTICE:
THIS APPLIANCE IS NOT RECOMMENDED FOR USE ON CODED OR PULSING SIGNALING CIRCUITS. HOWEVER, USE OF THE GTSM CONTROL MODULE IS PERMITTED TO

SYNCHRONIZE THE HORN.
w THE FOUR PULSE TEMPORAL PATTERN (TEMPORAL 4) CAN ONLY BE OBTAINED ON THIS PRODUCT WHEN USED IN CONJUNCTION WITH THE POTTER ELECTRIC GTSM
SYNCHRONIZATION MODULE OR GTSM SYNCHRONIZATION PROTOCOL.
SEE GTSM CONTROL MODULE MANUAL (550-0634, MANUAL ISSUE DATE (02-01-15) FOR SYNCHRONIZATION MODULE WIRING DIAGRAMS. GTSM MANUAL CAN BE

OBTAINED BY CALLING POTTER ELECTRIC SIGNAL COMPANY AT 1-800-325-3936.
Conventional Method:
You may connect the horn directly from a source of rated power without the use of a control module. However, the horns will NOT be synchronized.
