About
Cygnus SN-Pro delivers true wireless at scale and complexity, providing wireless stability that rivals hardwired systems - even on installations traditionally considered only possible with hard-wired or hybrid alarm systems.
With MeshBeyond™ technology, SN-Pro ensures robust connectivity and reliability across large, complex projects. Combined with our proprietary panel that's a joy to use, SN-Pro offers a seamless experience for installers and end-users alike.
Installation is significantly faster than both hardwired and hybrid systems, reducing project timelines and costs without compromising safety or performance.
Features
Cygnus SN-Pro
100% Wireless
Cygnus SN-Pro is EN 54 certified and BS 5839 compliant, eliminating the need for fire-resistant cabling, restrictions on device locations, and multiple loops that require protection against failure. There's no requirement for cable damage mitigation, no combustible fixings, and no risk of inadequate wiring or circuit overload.
With SN-Pro, there are no wired boosters, translators, or any other wired elements - removing the stressful first fix stage of installation. The wireless mesh network requires no gateway expanders or loop-powered translating devices, speeding up installation even further. The absence of substantial cabling reduces your carbon footprint and minimises the need for engineers on site.
Reliable and Robust
SN-Pro runs on lithium battery-powered radio devices as part of a self-healing MeshBeyond™ network, where nodes connect dynamically and non-hierarchically for highly efficient performance.
Each device has multiple communication paths, and our channel-hopping technology automatically selects the strongest signal route for optimum reliability. Devices offer a long radio range of up to 350m (unobstructed) using omnidirectional antennas.
Easy to Install
By removing costly and time-consuming cabling, SN-Pro dramatically reduces engineering time and overall project costs. Ideal for retrofit installations where disruption is minimised, and for new builds with tight deadlines.
Installation is further enhanced by our Mesh Analyser tool, which simplifies commissioning and ensures network integrity.
Easy to Adapt
The absence of cabling makes it simple to move or relocate detectors and other devices. Extending the system is quick and efficient, making SN-Pro perfect for buildings likely to be renovated or expanded.
Easy to Configure
SN-Pro supports up to 511 devices per panel and 96 zones, with the ability to network up to 5 panels, delivering a combined solution of over 2,000 devices.
Our configuration software includes full system design and cause-and-effect functionality. It runs on any Windows device and communicates with remote devices via wired or wireless connection.
Easy to Use
The proprietary touchscreen panel provides a clear system overview and sends reports and alerts for alarms, low battery, and faults - all identifiable by location.
EN 54 Certified
SN-Pro comprises a range of EN 54 compliant fire detection and alarm devices, suitable for permanent installation across all building environments.

Mesh Analyser - Enhanced Diagnostic Tool
The Cygnus Mesh Analyser software provides a graphical display of a mesh network, showing mesh signal strengths and connection paths for each device. It interrogates the mesh, revealing current and historical connection paths, and generates PDF reports with recommendations to strengthen network health.
The free software is downloadable from the Cygnus support portal and works with mesh files from the SN-Pro control panel, making installations and commissioning more efficient.
Site Survey Kit
Deploy three bespoke detectors to replicate the mesh network and confirm system suitability for the environment. During the survey, signal strengths and multiple connection paths are demonstrated, ensuring optimal device placement and reliability. This saves time during installation and reduces future callouts.
Portable Programming Unit (PPU)
The PPU enables wireless firmware updates and device configuration changes on site, even in hard-to-access areas. Devices are placed in programming mode, updated, and seamlessly rejoin the mesh network.
