Apollo AlarmSense A1R Heat Detector with Sounder Visual Indicator Base (55000-198APO)

The Apollo AlarmSense A1R Heat Detector with Sounder Visual Indicator Base (55000-198APO) combines heat detection, audible alarm signalling, and visual indication in a single device. As an A1R rate-of-rise heat detector, it monitors both the temperature and the rate at which the temperature increases, making it to able to detect developing fires earlier than a static heat detector in many applications.

The 55000-198APO incorporates a fixed upper temperature threshold while also responding to rapid increases in temperature. This makes it suitable for environments where smoke detectors may not be appropriate, such as areas affected by dust, smoke, or airborne contaminants during normal operation.

The integrated sounder visual indicator base provides local audible and visual alarm notification, while high visibility LEDs offer 360° visibility, making sure alarm conditions can be seen from multiple directions.
