Ajax EN54 FireProtect Heat Detector with Sounder White

Heat detection is the preferred sensing method in environments where smoke detectors would generate false activations, such as commercial kitchens, plant rooms, workshops, and garages. The Ajax EN54 FireProtect Heat and Sounder device addresses this by providing certified heat detection in exactly these spaces while incorporating an audible sounder into the same unit.

The integrated sounder simplifies system design by removing the need for a separate sounder in smaller rooms or zones where only one device is planned. When the heat threshold is exceeded and the system activates, the built-in sounder provides an immediate local alert alongside the system-wide alarm response.

As an EN54-certified wireless device, it connects to the Ajax EN54 Fire Hub over the Ajax radio protocol, contributing to a fully compliant wireless fire detection installation. This removes the need for fire alarm cable between the device and the panel, which is a substantial advantage in buildings where cable routes are difficult or disruptive to install.

For fire alarm engineers specifying compliant systems in commercial kitchens, industrial units, plant rooms, and similar areas across London and the wider UK, this combined heat and sounder device provides a practical and certificated solution in a single wireless unit.
