Rain Sensor

The Rain Sensor, included with all LC-II Control Switch Kits, features an improved aesthetic appearance and increased corrosion resistance.

The Rain Sensor can be used with an LC-II Control Switch, RS Module, or IR Receiver.

To see how a Rain Sensor integrates with all of our other components to form a complete system for motorizing your casement, awning, and skylight windows, take a look our wiring diagram. It should give you a basic guideline for planning and creating your own motorized window and skylight system.

Price: $18.95 USD
Part No. RAINS01	-	Rain Sensor, Gold Plated.

Rain Sensor Installation Instructions

You can download the Rain Sensor Installation Instructions (445KB) to familiarize yourself with the Rain Sensor installation. The installation instructions are in Adobe PDF format and require Adobe's free Acrobat Reader. If you don't have Acrobat Reader you can download it from Adobe's website.

The Rain Sensor can be used with an LC-II Control Switch, IR Receiver, or RS Module to automatically close the windows/skylights when moisture is detected. Do Not use the Rain Sensor if the window/skylight is being used as a smoke vent or if Open & Hold is required.

Step 1 - Gather your Tools

#2 Philips head screwdriver
1/8" (3.0 mm) bladed screwdriver
1/10" (2.5 mm) bladed screwdriver
Electric drill motor
Drill bits (1/4" and 1/16")
An awl for marking mounting holes
22 AWG, 2-conductor, shielded, twisted-pair, wire for the sensor

Step 2 - Run Electrical Wires

A Rain Sensor can be connected to every LC-II Control Switch, RS Module, and IR Receiver in your system. If RS Modules or IR Receivers are used to control multiple LC-II Control Switches, the Rain Sensor can be connected to one of them to provide group control. The Rain Sensor can also be connected to the LC-II Control Switch if only localized control is desired.
Use 22 AWG, 2-conductor, shielded, twisted-pair wire, 50 ft. (15 m) maximum.
Run the wires between the Rain Sensor and the LC-II Control Switch, IR Receiver, or RS Module. See the wiring diagram for more information. Run low voltage wires at least 12" away from high voltage wires to avoid any electrical interference.

Step 3 - Install Rain Sensor

Use care not to bridge the contacts with the head of the screw when mounting the Rain Sensor.
Install the Rain Sensor with the "grid" exposed. Mount at an angle to prevent moisture from pooling on the grid.
Consider prevailing winds when placing the sensor. Keep away from obstructions.
The Rain Sensor can be mounted outside (maximum sensitivity) or inside the vent edge (minimum maintenance).
Connect the Rain Sensor to the LC-II Control Switch, IR Receiver, or RS Module. Connect the shield to GROUND (G). Refer to the wiring diagram for more information.

Open & Hold Switch Installation

This feature is designed for use with thermostat and smoke vent systems. Note: DO NOT use Open & Hold Switches with a Rain Sensor because the Rain Sensor will override the Open & Hold Switch.
Use a SPST (Single-Pole, Single-Throw) continuous contact relay or switch for this low voltage control application.
Connect the controlling contact between the OPEN (O) and GROUND (G) connectors on the LC-II Control Switch.
When this contact is held closed the unit(s) will open, and remain open, regardless of the state of any other inputs, except for the Rain Sensor.
