From design and installation through to monitoring, maintenance and emergency response, Securitas provides end-to-end wireless fire alarm services.
Our WES3 system offers rapid setup, full system testing (without full evacuation), and real-time fault alerts. You’ll get 24/7 protection with smoke and heat detection, remote monitoring, and IP-rated units made to endure harsh site environments.
The WES3 wireless fire & emergency alarm system is designed specifically for dynamic environments such as construction and refurbishment. It combines early warning, mobility and durability in one package. Because the system is completely wireless, you avoid complex wiring and reduce installation delays. Its mesh-network structure means any device can trigger a site-wide alarm, whether via smoke, heat or manual call point. Key features such as Inspection Delay (to reduce false alarms), full Isolation System Test Mode (so you can test parts of the system without disrupting all site work), and real-time system-notification help you maintain safety without interruption. The units are IP55 rated for outdoor use, have battery life up to three years, and can be integrated with building management systems and access control, giving you a robust, scalable, compliant solution from Securitas.
All aspects of the WES3 system are compliant with industry standards: EN54-25 certification, CE marking, and full alignment with relevant fire-safety and construction regulations. This ensures you’re meeting legal obligations and protecting lives.
Wireless setup, rapid deployment, and tools-free installation give you flexibility. Whether your site is moving phases, shifting locations, or adding cabins, WES3 adapts without extensive rewiring or disruption.
With real-time notifications, remote monitoring via REACT, and features like Inspection Delay and Isolation System Test Mode, you get control and awareness. Any system issue or fire alert is communicated immediately, helping you respond swiftly and avoid unnecessary evacuations or financial loss.
