Part of the ever-expanding life safety range

Adding another dimension to systems, the HEAT-WE raises the alarm if the room temperature reaches 57°C and above.

Perfect for areas such as kitchens, the HEAT-WE provides accurate and dependable fire detection, with prompt notification of any alarms via the always-connected app.

Fixed heat detection

With a fixed detection heat of 57°C, the two-way wireless heat detector provides continuous and reliable safety sensing which can be easily and efficiently added to any Pyronix system.

Loud and obvious alarms

The HEAT-WE has a built-in 85dB local sounder and flashing LED lights; providing a clear and obvious alarm when the environmental temperature reaches 57°C.

Be in control with full low-battery supervision

When the battery is running low on the radio module of the HEAT-WE, the detector will send a signal to the control panel to report the issue. If the user has the smart device app connected to the system, they’ll also receive a push notification to draw their attention to the fault.

Stay safe with tamper protection

If the housing of the HEAT-WE is dislodged, the rear tamper will trigger to alert that it is not fitted correctly.

Pyronix High Security Wireless Encryption Protocol

The two-way wireless protocol has been developed by Pyronix to ensure that the communication between all wireless system components are encrypted.

One-Push-To-Learn Button

The Enforcer two-way wireless protocol allows easy learning of all its peripherals – with the push of a button you can add any of the detectors or sensors to Enforcer wireless compatible control panels.

Signal Strength Indicator (SSI) on the Device

SSI in all Enforcer wireless devices allow them to be optimally positioned during installation, without the need to refer back to the panel.
