Safety equipment
which was designed to monitor electrical installations and equipment, alerting building occupants to the risk of an electrical fire long before it starts. With the ability to turn what would have been
an emergency situation into a simple maintenance task, the technology can be easily retrofitted to any existing system or new build project. It can be incorporated into sockets, consumer units and distribution boards – the key risk areas in a typical electrical installation – in order to provide the permanent monitoring of heat. In the event of temperatures exceeding 80°C, it can either automatically isolate power when an RCD is present, or instantly alert building occupants in a variety of ways, such as via a building management system, fire alarm system, or mobile device using the WES React system. The Thermarestor technology behind WES
Hotspot works by activating as soon as an abnormal heat reading (80ºC ± 5°C) is detected. Once activated, these single and multipoint sensors either automatically isolate the circuit supply by operating an RCD, or provide a signal to an alarm system long before the temperature can increase to the point of ignition. It can be connected to virtually any system to provide occupants with instant notification. The range has been independently tested and is compliant
with all applicable statutory regulations and requirements. A growing number of building owners and
operators are now seeking these smart, technology led approaches to fire safety and in particular pre ignition solutions that prevent a fire occurring in the first place. Advances such as this provide an effective, easy to fit solution that actively prevents electrical fires, making them highly valued by clients and building owners. An almost infinite number of potential users
(any building using electricity as a source of supply) can benefit. Whether in a residential tower block, school, hospital or historic landmark, smart technology such as this can eliminate electrical fires caused by overheating. Miniaturisation of the technology and
an extended life from battery powered devices allows these kinds of devices to be fitted in a vast range of consumer units, distribution boards, sockets and electrical equipment, protecting building occupants from some of the thousands of electrical fires that occur each year. As it is able to detect a fire before it starts,
this technology is more intuitive than existing protective devices, such as miniature circuit breakers and RCDs, because it responds to the excessive heat caused by wiring faults and overloads
