Section 4: W-SYNC Wireless Synchronization Module
4.1 Description
The wireless synchronization module works with wireless AV bases to provide audio and visual synchronization of a wireless notifica-
tion appliance to a wired notification appliance. Synchronization is only available with notification appliances that use the System Sen-
sor synchronization protocol. The W-SYNC also provides wireless control and monitoring of a Notification Appliance Circuit (NAC)
expander or power supply. It does not support the “whoop” pattern.
The wireless synchronization module operates from 24VDC power with supplemental battery support. A trouble will be generated at the
panel if batteries are not installed or at a low battery level. Synchronization is not available during supplemental battery operation. For
more information on the W-SYNC, refer to Document I56-6518 that ships with the product.
4.2 Wiring
The W-SYNC may be wired to compatible FACPs using an MDL3 Sync Module or the HPFF8/HPFF12 NAC Expanders. The synchro-
nized output wiring must be contained in the common enclosure of modules or wired in conduit in enclosures mounted within 20 feet of
each other in the same room with wiring in conduit.
When Class A zones are used, power supply wiring must be contained in the common enclosure with the W-SYNC, or the power supply
and W-SYNC must be in enclosures within 20 feet of each other in the same room with wiring in conduit.
