Apollo SIL Discovery Sounder Visual Indicator Base (45681-393SIL)

Apollo SIL Discovery Sounder Visual Indicator Base (Part No. 45681-393SIL)

The Apollo SIL Discovery Sounder Visual Indicator Base (45681-393SIL) combines audible and visual alarm notification with the advanced functionality of the Apollo Discovery protocol. Compatible with the full range of Apollo Discovery detector heads, the device provides flexible alarm signalling and allows users to configure sounder and visual indication settings directly from the fire alarm control panel.

The 45681-393SIL simplifies commissioning and maintenance by making engineers able to test and adjust each sounder locally using a magnetic wand. In addition, installers can control the sounder and visual indicator apart from each other, enabling customised alarm strategies to meet the needs of different environments.

Furthermore, users can select volume levels and tone options directly from the fire control panel. The device supports a wide range of alert tones that can serve purposes beyond fire alarms, making it particularly fitting for schools, hospitals, and nursing homes. The integrated soft start feature gradually increases the sound output, helping reduce distress and disruption in sensitive environments.
