Cooper Wheelock DSM-12/24-R Dual Sync Module
The Cooper Wheelock DSM-12/24-R Dual Sync Module provides synchronized control for multiple Wheelock notification appliances, ensuring that strobes flash in unison and temporal tones stay properly timed. Designed to manage two independent Class B circuits, this compact module simplifies installation and enhances system coordination in fire alarm and emergency notification systems.
Because it supports both 12VDC and 24VDC operation, the DSM-12/24-R offers flexibility across a wide range of system types and applications.
Synchronized Audio-Visual Notification
The DSM-12/24-R plays a critical role in maintaining synchronized flashing across connected strobes. This synchronization helps prevent disorienting, overlapping flashes, especially in spaces with multiple visual notification devices. It also keeps temporal tones in sync for horns and speaker-strobes, which improves intelligibility and ensures a consistent occupant experience.
In addition to improving clarity, synchronization supports compliance with NFPA and ADA standards. By preventing erratic or asynchronous operation, the module contributes to a safer and more effective emergency communication system.
Flexible Configuration for Multiple Zones
This dual sync module can independently manage two separate Class B output circuits, which allows installers to control different notification zones from a single module. Each circuit includes its own set of terminals, and the outputs remain synchronized as long as they operate on the same control signal.
Because of its compact footprint and straightforward wiring, the DSM-12/24-R fits easily into standard electrical enclosures or notification appliance circuit (NAC) cabinets. This design saves space while reducing the need for multiple single-function modules.
Reliable Integration with Wheelock Devices
The DSM-12/24-R integrates seamlessly with Cooper Wheelock’s wide range of horns, strobes, speaker-strobes, and other notification appliances. It supports synchronization protocols for Wheelock Series NS, Exceder, MT, and other compatible models. Installers can use this module in new installations or as part of a retrofit to bring existing systems into compliance with current code requirements.
Its wide voltage compatibility, durable design, and easy configuration make it a valuable component for both small-scale and large-scale fire alarm systems.
The Cooper Wheelock DSM-12/24-R Dual Sync Module ensures consistent, code-compliant synchronization of strobes and temporal tones across multiple circuits. Its dual output configuration, flexible voltage support, and seamless integration with Wheelock devices make it an ideal choice for fire alarm professionals. For projects that require reliable coordination of visual and audible signals, the DSM-12/24-R offers a compact and efficient solution.
