This allows the control of external devices like sirens or cutoff relays. It operates on a 9-12Vdc supply and includes two sensor connections with dimensions of approximately 60 x 45 x 20 mm (without mounting straps). The water sensors are charged with an extremely low voltage to prevent oxidization.
