Q. How many wireless sensors can you connect to the Siren Marine head units (Siren 3 or Siren 3 Pro)?

There are currently 5 kinds of wireless sensors, Battery, Bilge, Entry, High Water, and Temperature.  For best performance on most boats, we recommend 10-12 wireless sensors. Currently we limit the number of wireless sensors that can be paired with a Siren 3 PRO unit to 16.
