How WES3 protects your projects

The WES3 system comprises manual fire and medical alarm call points that are installed on site in accordance with the project’s Fire Plan. These call points are designed so that the system is interlinked, meaning that all areas receive the same audible and visual alert signal, even if the fire is contained to just one of them. Incorporating heat or smoke detectors into the network provides automatic cover 24/7, ensuring that your construction site is protected even when personnel are not present. The WES system works on a mesh protocol which enables the system to overcome signal obstacles such as steel structures and other signal interferences, therefore offering advanced protection. When coupled with REACT, all relevant personnel will be notified immediately via text message from anywhere, on site or off, if an alarm is activated.
