Apollo AlarmSense Sounder Visual Indicator Base (45681-509APO)

The Apollo AlarmSense Sounder Visual Indicator Base (45681-509APO) combines audible and visual alarm notification within a single detector base, providing an efficient and cost-effective solution for Apollo AlarmSense fire alarm systems. Designed exclusively for use with AlarmSense devices, the base makes the system design simpler while delivering reliable alarm signalling throughout the protected area.

The base incorporates both a sounder and a visual indicator, allowing a compatible detector to provide detection, audible warning, and visual notification from a single installation point. As a result, installers can reduce wiring complexity and minimise the number of devices required within the system.

Furthermore, the 45681-509APO constantly monitors the presence of the detector head. If the detector is removed, the base immediately identifies the condition and reports a fault to the system. Importantly, the sounder and visual indicator continue to operate even if a detector head is removed without authorisation, helping to maintain alarm coverage and system integrity.

To provide greater installation flexibility, the base is available with either a low- or high volume setting, while red and white caps can be fitted for standalone sounder visual indicator applications.
