CH-250 Multi-Way Wall Switch Vacancy Sensors are designed to replace standard single pole and
multi-way (3-way, 4-way) switches. They are ideal for any room with multiple entries, and any other
indoor space where vacancy sensor-based control with manual ON/OFF capability are desirable.
Like standard switches, you can press the ON/OFF button to turn the light or fan (controlled load)
ON and OFF. Unlike standard switches, the CH-250 automatically turns OFF the controlled load
after the coverage area has been vacant for a period of time (Time Delay). If motion is detected
within 30 seconds after it automatically turns OFF, the CH-250 automatically turns the load back
ON.
The CH-250 can be wired with up to three additional CH-250s for multi-way Manual ON/OFF of
one or several loads (up to one load connected to each CH-250). It can also be wired to up to
four RH-253 single pole momentary wall switches for multi-way Manual-ON/OFF Automatic-OFF
control of one load.
Lighted Switch
To help you locate the CH-250 in a dark room, the amber LED illuminates the ON/OFF button
while the controlled load is OFF. When the controlled load is ON, the LED is OFF.
Time Delay
The CH-250 keeps the load ON until no motion is detected by any of the related CH-250s for the time delay period. The time delay can
be selected by the user during set up. It can be adjusted to any of these fixed values:15 seconds/5 minutes/15 minutes/30 minutes. We
recommend that the time delay be the same in all sensors related to the same load. This makes it easier to understand the multi-way
control operation as well as trouble shooting. For additional information on how to adjust it, please read the SENSOR ADJUSTMENT
section of this installation manual.
Coverage Area
The CH-250 has a maximum coverage range of 180 degrees and a coverage area of 600 square feet (56 square meters). The sensor
must have a clear and unobstructed view of the coverage area. Objects blocking the sensor's lens may prevent detection thereby
causing the light to turn OFF even though someone is in the area.
Windows, glass doors, and other transparent barriers will obstruct the sensor's view and prevent detection.
