Apollo Addressable Heat Detector

The Apollo Addressable Heat Detector offers robust and accurate thermal fire detection for demanding environments where smoke detectors may generate false alarms. Utilizing a single thermistor network, the detector continuously monitors ambient air temperature and outputs a signal proportional to temperature changes. It is ideal for areas such as warehouses, loading bays, car parks, and other dirty or smoky locations where conventional smoke detection is unsuitable.

Classified as A2S (Type A & B), this detector will trigger an alarm at 55°C, making it suitable for early fire detection in a range of industrial and commercial applications. The detector is easy to install, resistant to insects, and unaffected by wind or pressure changes—ensuring dependable performance in challenging settings.

Product Features

Accurate Thermistor-Based Detection

Features a single thermistor sensor that provides a precise temperature-based signal output for consistent fire detection.

A2S Classification

Designed to alarm at 55°C, suitable for general-purpose applications under the EN54-5 standard for heat detectors.

Reliable Addressable Communication

Works within addressable fire alarm systems, ensuring fast alarm flag reporting and seamless integration with control panels.

Environmental Resilience

Insect-resistant, unaffected by atmospheric pressure and wind, and designed for dusty or smoky environments where standard detectors are less effective.

Easy to Install

Incorporates an electronics-free base for simple and secure mounting, reducing installation time and service complexity.

Ideal for Industrial Applications

Perfect for use in warehouses, car parks, loading docks, kitchens, and boiler rooms, where heat—not smoke—is the most reliable fire indicator.
