Cygnus SmartNet signals “breakthrough” in fully wireless fire alarm systems

The Cygnus SmartNet system comprises a comprehensive range of EN 54-compliant and Construction Products Regulation (CPR 305/2011)-certified fire detection and alarm devices suitable for permanent installation across all types of building environment. The devices include a choice of radio bases, with and without sounders and visual indicators, optical smoke, Type B heat detectors, PIR detectors and a combi detector, which has a smoke and A1R sensor, together with ceiling and wall-mounted VADs, Call Points and an interface.

Harbouring the capability for 511 devices to operate on one wireless system, a SmartNet network is built on a combination of these battery-powered radio devices, operating on a self-forming, self-healing mesh network using the SmartNet wireless protocol across ten frequency channels operating at 865-868 MHz.

A minimum of two communication paths to each wireless device and innovative channel-hopping technology makes the network extremely reliable, protecting against the risk of broken communication links, network redundancy and interference. In addition, SmartNet devices feature a long radio range, which extends up to 350 metres (unobstructed) with the help of a directional antenna. SmartNet enables installers to design 16-, 32-, 64- and 96-zone panel options with the possibility to network up to five panels together in a single system.

Game-changer for installers

“This wireless system is a game-changer for installers,” explained Austen Wells, sales manager at Cygnus. “For the first time, it offers the sector a fully wireless system, which is quick and easy to install, and can be scaled effectively from small to large installations.”

Wells added: “The system is designed to be fitted by SmartNet Certified Partners and Cygnus offers full training and technical support for those partners. SmartNet brings the significant operational and installation benefits of wireless technology to the market. With no need for wired boosters, translators or any other wired element, it removes the often stressful ‘first fix’ stage of an install.”

By eliminating the need for cabling during installation, a SmartNet system greatly reduces engineering time and the overall project cost. This enables faster and easier installation for new buildings, where project timescales are often extremely pressurised. It also opens up retrofit opportunities since wireless installation minimises occupant disruption and reduces the cost of rewiring.

The wireless mesh network system doesn’t require gateway expanders or loop-powered translating devices, which speeds up installation still further.

As a BS 5839-1 and EN 54-compliant system, SmartNet eliminates the need for fire-resistant cabling, restrictions on device locations and multiple loops, which need to be protected against failure. It also offers “superior safety” as there’s no requirement for cable damage mitigation, no combustible fixings, no possibility of inadequate wiring and no risk of circuit overloading or high circuit loads.

Configuration and commissioning

SmartNet is configured and commissioned using a Windows-based configuration tool on a PC, tablet or mobile device. The software includes an easy-to-use menu designed to guide engineers through each stage of the configuration and commissioning process. The tool also facilitates system diagnostics using any Windows device.

The SmartNet touch screen control panel offers a comprehensive overview of the system as well as the capability to send reports about alarms, low battery alerts and faults, all of which are identifiable by location.
