Wheelock 108006 Synchronization Module

The Wheelock DSM 12/24-R synchronization module (108006) coordinates synchronized horn, strobe, and horn/strobe signaling across notification appliance circuits in fire alarm and emergency notification systems. Designed for indoor use with 12 VDC or 24 VDC input and up to 3 A per circuit, it supports one Class A NAC or two Class B NAC configurations when used with Wheelock notification appliances. It mounts in a standard electrical backbox, is compatible with standard fire alarm control panels, and enables temporal-code horn operation, synchronized strobes, and audible silence to support NFPA-compatible evacuation signaling. Commonly installed in commercial buildings, schools, hospitals, warehouses, industrial facilities, and other public occupancy environments, it is used for retrofit projects and system upgrades requiring reliable synchronized audible and visual emergency notification. Alternate identifications include 108006; as part of the Wheelock/Eaton family, it is designed for use with Wheelock notification devices, with common replacement options including the System Sensor MDL Synchronization Module and Gentex AVSM Synchronization Module.
