Overview Features Technical Data Downloads & Resources

The Apollo Orbis A1S Conventional Heat Detector (ORB-HT-11166-APO) is designed for reliable fire detection in environments where standard smoke detectors may not be suitable.

This detector utilises a high-quality thermistor to continuously monitor temperature, providing a precise voltage output that responds to changes in ambient air temperature. It’s ideal for dusty, dirty, or smoky conditions where smoke detectors might give false alarms.

Key features include a red LED that confirms operation at startup, SensAlert® technology with a yellow LED to indicate faults, and FasTest® functionality that allows engineers to test and confirm operation in just four seconds.

Durable, efficient, and engineered by Apollo, the Orbis A1S is a trusted choice for a wide range of commercial and industrial applications.

Works where smoke detectors aren’t suitable
Perfect for dusty or smoky environments
Red LED confirms operation at startup
Yellow LED alerts to faults with SensAlert®
FasTest® verifies detector function in just 4 seconds
