Wheelock® DSM Sync Module by the Eaton company
Synchronized Notification for Reliable, Unified System Performance
The Wheelock® DSM Sync Module used with Kidde Fire Systems conventional and intelligent controls from KiddeFenwal ensures seamless coordination across your notification circuits — delivering synchronized audible and visual alerts for fire and life safety systems. Designed for use with Wheelock® Series Exceder, AS/AH, RSS, and RSSP appliances, this compact module enables consistent code 3 horn patterns and synchronized strobe flashes, .
With the ability to silence audible devices while maintaining strobe operation and to control both Class A and Class B NAC circuits, the DSM Sync Module helps ensure clear, code-compliant notification while simplifying wiring and system integration.
Key Advantages
- Unified System Operation
Synchronizes horn and strobe appliances to maintain consistent, intelligible alerts across multiple notification zones. - Audible Silence Capability
Allows horn deactivation while maintaining synchronized strobe output for occupant visibility during alarm acknowledgment. - Dual Circuit Control
Supports either one (1) Class A or two (2) Class B NAC circuits with independent supervision. - Easy Integration
Works with AEGIS-PHX™ ,ARIES™-SLX and ARIES™-MLX Control Units to simplify notification appliance circuit (NAC) design.
- Compact & Efficient
Uses a single pair of wires for both audible and visual devices, reducing installation complexity. - Daisy-Chaining Capability
Up to 20 DSM modules can be interconnected to extend synchronized operation throughout large facilities. - Code-Compliant Output
Meets NFPA 72 Temporal Pattern (Code 3) requirements when used with Wheelock® appliances.
Applications
Ideal for installations where synchronized operation and clear, code-compliant signaling are required, including:
- Commercial and institutional buildings using mixed visual/audible signaling devices
- Industrial and hazardous environments requiring NFPA 72–compliant alerts
- Multi-zone or large facilities requiring unified signaling across separate NAC circuits
- Retrofit systems where control panels lack native synchronization capabilities
