Apollo Series 65A Photoelectric Smoke Detector – high sensitivity (55000-328APO)

The Apollo Series 65A Photoelectric Smoke Detector – High Sensitivity (55000-328APO) provides reliable early warning of fire by using the proven light scatter principle to detect smoke particles. Designed for applications that require enhanced smoke sensitivity, 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 the emitted light onto the sensor, allowing the detector to identify a fire condition and initiate an alarm. As a result, the 55000-328APO responds particularly well to slow burning and smoking fires, making it ideal for accommodation areas and escape routes.

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

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