MOS-21 Sensor Description
The 21 series MOS sensor (also referred to as the sensor in this guide) is a
wireless, energy harvesting, ceiling mount, passive infared (PIR) occupancy
sensor. Used for indoor applications, the detector is optimized for ceiling heights
of 8 - 10 feet (2.4 - 3m).
NOTE: The MOS is a solar powered device that absorbs solar energy storing it
for use during low light periods. Before assigning the MOS device to a receiver/
controller, the device should be exposed to a good light source for a minimum of
5 minutes or install the start assist battery.
