Wireless Temporary Fire Alarm and Evacuation Alert
System for Construction Sites
Helping contractors comply with NFPA 241
The system is comprised of several different types of units for optimum protection including manual evacuation and medical call points, smoke and heat sensors, interface units, and more. With no wires or power supply required to install, each unit can be placed unobtrusively according to the site’s unique monitoring needs. This is a system that can grow with your site, adding more units as construction progresses.

How WES3 protects your projects
The WES3 system comprises manual evacuation 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 sensors into the network provides automatic cover 24/7, ensuring that your construction site is protected even when personnel are not present. 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.
