Apollo 55000-393APO AlarmSense Integrating Optical Smoke Detector Base & Sounder Set

The Apollo 55000-393APO AlarmSense Integrating Optical Smoke Detector Base & Sounder Set combines intelligent optical detection with integrated audible signalling in a single, coordinated package.

This set includes the Apollo 55000-391 Integrating Optical Smoke Detector and a compatible AlarmSense sounder base, providing detection and local alarm notification from one device location. The integrating optical detector is specifically designed for environments where transient smoke or brief contamination may occur, helping to reduce unwanted alarms by monitoring and filtering short-term smoke sources before signalling.

When activated, the sounder base delivers a clear audible warning with selectable volume levels, ensuring effective notification at the point of detection.

As part of the AlarmSense range, the unit connects to a simple two-wire circuit shared by detectors, sounders and call points, reducing cabling requirements and streamlining installation.
