- The SB2 floats on the water and constantly monitors for sub-surface disturbances caused by entry into the pool.
- If intrusion is detected, a loud 85 dB alarm sounds at the pool and simultaneously triggers the indoor receiver.
- The alarm automatically wakes up and performs a self-test each time it is placed in the water.
