Installation
2. Installation
2.1 Packaging
The stand alone rain sensor assembly comes supplied in a polythene bag.
2.2 Mounting location
The stand alone rain sensor should be mounted on an external façade of the building. It must be mounted
in a location that is easily subjected to rainfall.
2.3 Fixing
Loosen the two bracket adjustment lock screws and fold the bracket up toward the body of the sensor.
Offer the sensor up to the mounting surface with the sensor contacts facing upward. Mark through the
three fixing holes with a marker pen and place the sensor to one side. Drill appropriately sized pilot/fixing
holes and use suitable plastic plugs where appropriate. Note that it is recommended that 30mm No6 pan
head screws are used to secure the body in place. These should preferably be brass or steel that has been
treated for external use (e.g. black japanned). Fix the sensor bracket to the wall using three fixing screws.
Adjust the sensor body so that incident rain will readily run of the sensor’s face and lock up the two bracket
adjustment lock screws.
2.4 Connection details
2.4.1 Preamble
The stand alone rain sensor leaves the factory with all fixings pre-sealed to prevent water ingress. Should it
become necessary to open the enclosure during the installation/configuration process, then it is important
that this sealant is replaced using a suitable silicon-based sealant upon completion of the commissioning
process.
