Introduction to the Pyronix HEAT-WE Wireless Heat Detector
The Pyronix HEAT-WE Wireless Fixed-Temperature Heat Detector (57C) is a purpose-built detector for environments where traditional smoke detection can be unreliable. Designed to integrate with Pyronix Enforcer control panels and the ProControl+/PyronixCloud ecosystem, this thermistor-based detector triggers at a fixed temperature of 57C, provides a local 85 dB sounder, and communicates over two-way encrypted 868 MHz radio. Its combination of robust detection, wireless convenience and diagnostic tools makes it a strong option for both domestic and commercial installations such as kitchens, garages or workshops.

Detailed specifications and benefits
The HEAT-WE is a fixed-temperature (57C) device that uses a thermistor to detect sustained high temperatures rather than smoke particles. This makes it especially useful where smoke detectors would generate frequent false alarmsfor example, above cookers, in garages with vehicle exhaust, or in dusty workshop environments. The unit includes an 85 dB sounder measured at 3 m and a status LED for local confirmation and walk-test checks.
This wireless detector runs on one replaceable 3V CR123A battery, providing an estimated RF battery life of approximately two years under typical conditions. It reports low battery thresholds (RF low alert at approximately 2.5 V and sensor low alert around 2.6.7 V DC) to the control panel, enabling proactive maintenance and reducing the risk of undetected power loss.
Operating on 868 MHz with Pyronix two-way protocol, the HEAT-WE supports encrypted communications (TDE encryption / rolling code), supervision, and intelligent jamming detection. Two-way communication enables the control panel to confirm device status and receive diagnostics, while tools such as Signal Strength Indicator (SSI) and Instant Two-Way Device Control (ITDC) simplify site commissioning and troubleshooting.
The unit measures 120 52.45 mm (diameter depth) and weighs around 172 g including the battery. It is rated to operate between 10C and +50C and in humidities from 590% non-condensing. These ranges cover most indoor spaces where heat-only detection is appropriate, but installers should always confirm suitability against local codes and the environment in question.
Designed to be used only with compatible Pyronix Enforcer control panels, the HEAT-WE includes tamper protection to notify the panel when the cover is removed. It supports programmable supervision and low battery reporting so administrators can configure monitoring behaviour suited to each installation. The device is CE marked (see datasheet for details); installers should consult the datasheet and installation guide for full regulatory and wiring information: https://cdn.dynamictech.uk/Files/Products/alarms/heat-we-datasheet.pdf
Use cases and scenarios where the HEAT-WE excels
The HEAT-WE was built for environments where smoke detectors either would be unreliable or would generate nuisance alarms. Typical scenarios include:
- Domestic kitchens:In busy kitchens or those without effective ventilation, steam and cooking fumes can trigger smoke detectors. A fixed-temperature heat detector avoids these false alarms while still providing alarm coverage for genuine heat events such as grease fires.
- Garages and boiler rooms:Areas with car exhaust, oil mist or particulate matter can confuse optical smoke sensors. Heat detection provides a clearer indication of dangerous temperature rises that signal a real fire risk.
- Workshops and industrial spaces:Dust, metal filings or airborne debris often set off smoke detection. The HEAT-WE reduces nuisance activations while providing robust heat sensing for areas with machinery or stored materials.
- Secondary detection in mixed systems:For properties that already have smoke detectors in living spaces, heat detectors like the HEAT-WE are often used in tandem for complete coverage where smoke detectors are unsuitable.
Comparisons with similar products and approaches
When choosing a fire or heat detector, several comparisons matter: sensing method (fixed-temperature vs rate-of-rise vs smoke), wired vs wireless, and alarm system compatibility.
Smoke detectors detect particles and are essential for early detection in most living spaces. However, in environments prone to nuisance alarms, heat detectors (especially fixed-temperature models like the HEAT-WE) become preferable because they respond only to temperature extremes rather than particles. Rate-of-rise heat detectors react to rapid increases in temperature and can detect fast-developing fires earlier than fixed-temperature units, but they are more complex and may be more sensitive to transient temperature changes. The HEAT-WEs fixed 57C threshold offers predictability and reduced false alarms where smouldering or slow rises are less of a concern.
Wired detectors require cabling and may be chosen for large or new builds where running cable is straightforward. Wireless devices like the HEAT-WE reduce installation time and are ideal for retrofits. Two-way encrypted protocols and supervision also make modern wireless devices reliable and secure choices for professional installations.
Other manufacturers offer heat detectors with similar ratings and features. Differences often come down to integration (which control panels they support), encryption and supervision features, battery life, and commissioning tools. The HEAT-WEs combination of Pyronix two-way encrypted communications, SSI and ITDC tools positions it strongly for installers using the Enforcer ecosystem. When comparing, look at compatibility, regulatory approvals, local support and commissioning aids as well as basic spec metrics such as trigger temperature and sound level.
Customer feedback and installer impressions
Where formal consumer reviews are limited, feedback from installers and system integrators provides useful insight. Installers frequently highlight a few recurring positives for the HEAT-WE:
- Simple wireless enrolment and reliable two-way supervision make commissioning faster and reduce post-install callbacks.
- Fixed 57C threshold is reliable in nuisance-prone areas such as kitchens and garages, and the local 85 dB sounder provides immediate audible alerting when the system activates.
- Diagnostic aids such as SSI and ITDC save onsite time by showing signal quality and allowing remote control checks during installation.

Conclusion: why choose the Pyronix HEAT-WE?
The Pyronix HEAT-WE Wireless Heat Detector is a practical, professionally focused solution for environments where smoke detection is impractical. Its fixed 57C trigger, integrated 85 dB sounder, two-way encrypted 868 MHz communications and commissioning tools like SSI and ITDC make it a reliable addition to Pyronix Enforcer systems. For installers and building owners looking for a wireless heat detector that balances false-alarm resistance with robust diagnostics and supervision, the HEAT-WE is a compelling choice.
Before purchase and installation, verify compatibility with your control panel, consult the datasheet and installation guide, and ensure that heat-only detection meets local regulations for the intended application.
