Apollo Series 65A Photoelectric Smoke Detector (55000-327USA)

The Apollo Series 65A Photoelectric Smoke Detector (55000-327USA) provides reliable early warning of fire by using the proven light scatter principle to detect smoke particles. Designed for a wide range of commercial and residential applications, the detector responds quickly to developing fire conditions while helping to minimise nuisance alarms.

The detector uses a pulsing LED and optical sensing chamber to continuously monitor the air for smoke. When smoke enters the chamber, it scatters light onto the sensor, allowing the detector to identify a fire condition and initiate an alarm. As a result, the 55000-327USA responds particularly well to slow burning and smoking fires, making it an excellent choice for protecting bedrooms, escape routes, and other occupied areas.

In addition, Apollo has designed the detector housing to match the Series 65A Ionisation Smoke Detector, creating a consistent appearance throughout the installation. The integrated indicator LED remains clear during normal operation and illuminates red during alarm conditions, enabling users to identify activated detectors quickly.

Furthermore, the detector operates reliably across a wide voltage range and remains unaffected by wind or atmospheric pressure changes, helping to maintain consistent performance in a variety of environments. Optional flashing LED and magnet operated test switch versions are also available to simplify testing and maintenance.
