Eaton Wheelock DSM-12/24-R

Eaton Wheelock DSM-12/24-R Dual Sync Module (Red)

The Eaton Wheelock DSM-12/24-R is a dual synchronization module designed to provide synchronized audible and visual notification for fire alarm and emergency communication systems. Operating at 12 or 24 VDC, it ensures compliance with NFPA 72 standards by delivering synchronized temporal (Code 3) horn patterns and strobe flashes across multiple notification appliance circuits (NACs).

Key Features

• Dual Circuit Support: Controls either one Class A or two Class B NAC circuits, offering flexibility in system design.

• Audible Silence Capability: Allows the horn to be silenced while maintaining strobe operation, facilitating effective communication during different phases of an emergency.

• High Current Handling: Each circuit can handle up to 3 amperes at 12 or 24 VDC, accommodating a wide range of notification appliances.

• Low Current Draw: Efficient design with low operating current, reducing overall system power requirements.

• Synchronization: Provides synchronized strobe flashes at one flash per second and synchronized temporal (Code 3) horn output, enhancing occupant recognition and response.

• Compatibility: Works with a variety of Wheelock devices, including Series AS, AH, MT, RSS, RSSP, CH70, E, EH, ET70/90/1080, ELSPST, ELHS, and ELFHS appliances.

• Daisy-Chaining Capability: Supports interconnection of up to 20 DSM modules for synchronized operation across multiple circuits.

• Mounting: Designed for wall mounting in a standard 4-11/16” x 2-1/8” deep backbox, simplifying installation.

• Regulatory Compliance: Meets UL 464, UL 1971, ULC, CSFM, and NFPA 72 standards, ensuring adherence to safety and performance requirements.
