🔹 WATSN Accessories – NF004 (AC220V Pulse Fire Linkage Module)
The WATSN NF004 is a Fire Protection Function Module designed for use with WATSN Automatic Transfer Switches (ATS) and Remote Transfer Switches (RTS). This accessory provides an AC220V Pulse Fire Linkage function, enabling the transfer switch to receive pulse signals from fire alarm and emergency systems and perform predefined safety operations during fire incidents. The NF004 corresponds to the X4-AC220V Pulse Fire Module in the WATSN accessory range.
Designed for seamless integration with building fire protection systems, the NF004 enhances emergency response capability by allowing coordinated operation between fire alarm panels and power transfer equipment. Its modular plug-in design enables easy installation and expansion without modifying the main transfer switch assembly. WATSN controllers support multiple add-on function modules, providing flexible customization for project requirements.
The NF004 is ideal for commercial buildings, industrial facilities, hospitals, data centers, telecom installations, and critical infrastructure where AC220V pulse fire alarm signals are used for emergency power control.
