Hochiki ATJ-EN Addressable Heat Detector | Ivory

The Hochiki ATJ-EN is a versatile, intelligent heat detector that combines a variable temperature sensor with a rate-of-rise element. Both sensing modes are controlled directly by the fire alarm control panel, allowing the system to activate either one or both elements depending on the application.

This flexible configuration ensures accurate and dependable fire detection, particularly in environments where smoke detectors may be unsuitable. Fully compliant with EN54-5 standards, the ATJ-EN is compatible with Hochiki’s ESP addressable protocol, making it an excellent choice for a wide range of addressable fire alarm systems.
