Product Spotlight – Wi-Fyre Wireless Optical Detector


Wireless fire detection systems have been available for some time now. Modern wireless technology provides a reliable, easy to install battery powered solution for temporary or permanent applications. The biggest advantage of wireless fire detection is that it is completely wire-free; it eliminates the need for lengthy cable runs, can be installed without causing too much disruption to property and the reduced installation time alone can provide significant cost savings.

However, while completely wire-free detection solutions are suitable for a plethora of applications, they are not always the best choice. They typically require more maintenance, large systems can be extremely expensive and there are still some concerns over reliability. That is why many installers and designers are now opting for a hybrid solution that incorporates both hardwired and wireless fire detection technology.


Wi-Fyre wireless fire detection provides a flexible choice for wireless detection integration and control. The Wi-Fyre hybrid detection solution enables hardwired and wireless detection technology to coexist as part of the same detection system.

Wi-Fyre can be used as part of a new fire detection solution or used to upgrade, extend or replace elements of an existing hardwired installation. This gives the system designer the freedom to use wireless devices in situations where cabling may be too expensive, running new cabling may be too disruptive or where speed of installation is a priority.

A Wi-Fyre system consists of at least one Wi-Fyre Wireless Transponder, installed into the fire alarm control panel’s wiring via a compatible interface. Each transponder can then communicate with upto 30 mixed wireless devices. There are a variety of wireless devices available in the Wi-Fyre range, including manual call points, sounders, input/output devices and heat and smoke detectors.

Wi-Fyre Wireless Optical Detector

  • EN54-25 approved
  • 868 – 870 MHz operating frequency
  • Powered by lithium metal batteries
  • Modern design
  • 360 degree LED indication

Wi-Fyre Wireless Optical Detectors use a pulsing IR LED and photodiode to detect IR scatter that is caused by smoke entering the chamber. They are powered by lithium metal batteries and are housed in a stylish, modern enclosure that features 360° LED indication.

These wireless optical detectors are powered by four lithium metal AA cells with an expected battery life of up to three years.

Wi-Fyre devices are certified to EN54-25, the European standard for wireless fire alarms which dictates that all wireless fire alarm systems sold in Europe must be tested by a 3rd party test house to ensure that they reach specific requirements.

Wi-Fyre is approved by TUV for safe use and installation in any European Union country and bears the CE mark to show that it complies with all the applicable directives including the CPR, EMC and the Low Voltage Directive (LVD).

Wireless Range

Wi-Fyre Optical Detectors communicate with transponders via secure radio frequencies of 868 – 870 MHz. These detectors provide detection coverage of 100m2 and have a wireless range of 150 metres across open areas.

A Wi-Fyre Survey kit is available, and must be used, to test the signal between the detectors’ base and the Wi-Fyre Transponder. This ensures that the signal is strong enough for the system to operate safely and efficiently. A Wi-Fyre Survey Kit is available for purchase or hire from Eurofyre and includes everything you need to conduct and document a complete survey with out-of-the-box operation.
