The Wheelock POWERPATH (PS-8-LP) by Eaton is a supervised remote power supply/battery charger in a low profile cabinet that is used for supervision and expanded power driving capability of fire alarm Notification Appliance Circuits (NAC). The PS-8-LP is filtered and regulated and provides 8 amps of power distributed across 4 outputs.

The power supplies may be connected to any 12V or 24V (FWR or DC) Fire Alarm Control Panel (FACP) by using a NAC or a "Dry Contact." Primary applications include NAC expansion (supports ADA requirements) and auxiliary power to support system accessories. This unit provides filtered and regulated 24VDC, up to four (4) Class "B", two (2) Class "A", or two (2) Class "B" and one (1) Class "A" Notification Appliance Circuits. With the optional plug-in PS-EXP module the unit supports (8) Class "B" or (4) Class "A" Notification Appliance Circuits. Additionally, an auxiliary power output of 2.5 Amps (disconnected upon AC power loss or an alarm condition) or up to 0.240 A of constant power on the PS-8-LP.

The Wheelock power supplies can accommodate 7 AH batteries inside its lockable chassis. Using an external battery cabinet it can charge up to 33 AH batteries (pending UL testing). Two FACP NAC circuits or two "Dry" contact initiating circuits can be connected to the inputs. These inputs can then be directed to control supervision and power delivery to any combination of the four (4) outputs. Each output is rated at 3.0 Amps (Class "B") or (Class "A") and can be programmed to generate a steady or Code 3 temporal horn sound and a strobe output under alarm condition. Total load for PS-8-LP NAC circuits must not exceed the power supplies rated output.

The DSM Dual Synchronization Module is a specialized control device designed to synchronize notification appliances such as horns and strobes within fire alarm systems. It is commonly used with Wheelock notification devices to ensure consistent flash patterns and audible signals across multiple circuits. The DSM Dual Synchronization Module enables dual NAC (Notification Appliance Circuit) synchronization, making it suitable for systems requiring coordinated signaling across different zones. With its ability to manage multiple outputs while maintaining synchronization, it plays a critical role in improving visibility, audibility, and compliance in fire alarm installations.

Features

• Provides synchronization for Wheelock horns and strobes
• Supports dual NAC outputs for multi-zone control
• Ensures consistent strobe flash timing across all connected devices
• Compatible with a wide range of Wheelock notification appliances
• Designed to eliminate signal overlap and irregular patterns
• Enables uniform audible and visual alerts in large facilities
• Simple integration with existing fire alarm NAC circuits

Benefits

The DSM Dual Synchronization Module enhances fire alarm system performance by ensuring that all connected notification devices operate in perfect synchronization. This eliminates confusion caused by unsynchronized strobes and improves visibility during emergency situations. It also helps meet compliance requirements for synchronized signaling in commercial buildings. By supporting dual circuits, it allows efficient management of multiple zones without requiring additional modules. Its ability to deliver uniform alerts across large areas makes it especially valuable in facilities such as warehouses, offices, and public buildings where clear communication is essential.
