Apollo Discovery UL Sounder Visual Indicator Base – red LED (45681-524USA)

Apollo Discovery UL Sounder Visual Indicator Base – Red LED (Part No. 45681-524USA)

The Apollo Discovery UL Sounder Visual Indicator Base – Red LED (45681-524USA) combines audible and visual alarm signalling with the advanced functionality of the Apollo Discovery protocol. Designed for use with Discovery and compatible XP95A systems, the device provides flexible alarm notification while allowing extensive configuration directly from the fire alarm control panel.

The 45681-524USA allows installers and maintenance personnel to test and configure sounders locally using a magnetic wand, simplifying commissioning and routine maintenance. In addition, the sounder and beacon can be configured independently, providing greater flexibility when designing alarm notification strategies for different environments.

The device supports a range of tones that can be used for purposes beyond fire alarms, making it particularly suitable for schools, healthcare facilities, and other buildings that require differentiated alert signals. It also offers a soft-start option, helping to reduce disturbance in sensitive environments such as hospitals and nursing homes.
