Apollo AlarmSense Integrating Optical Detector and Sounder Base (55000-393APO)

The Apollo AlarmSense Integrating Optical Detector and Sounder Base (55000-393APO) combines optical smoke detection and audible alarm notification in a single unit, providing an efficient and cost-effective fire protection solution. Designed for use with Apollo AlarmSense fire alarm systems, the detector uses the proven light scatter principle to identify smoke particles and provide early warning of developing fire conditions.

Unlike standard optical smoke detectors, the 55000-393APO continuously monitors smoke levels and can distinguish between genuine fire conditions and temporary smoke events. By identifying and discarding transient sources of smoke, the detector helps reduce nuisance alarms while maintaining reliable fire detection performance.

The detector responds particularly well to slow-burning and smouldering fires, making it ideal for protecting bedrooms, escape routes, and residential accommodation. In addition, the integrated sounder provides local audible alarm notification, helping occupants respond quickly when a fire condition is detected.

Furthermore, Apollo incorporates a 20-second alarm verification delay, allowing the detector to assess smoke conditions before entering alarm mode. This feature helps minimise false alarms in environments where temporary smoke may occasionally be present.
