A totally weatherproof and self contained rain detection unit which is used to signal when rain hail or sleet is falling. Primarily used by the BMS industry to signal when skylights should be closed these units feature a heated detection comb to prevent the unit activating in frosty conditions or when Dew is forming.
The unit has an adjustable stainless steel bracket to allow it to be fixed at a suitable location on the building. The unit requires a 24Volt supply for the heater and is designed for use with leak detection modules, Panels or digital inputs of BMS systems. These units should not be directly connected to a DC monitored source. To do so would destroy the sensing comb after only a few operations.
