User Manual
Feature
The Motion Detector is a KRC Zigbee enabled device which is fully compatible
with any KRC product
This Motion Detector can control our modules via controller setting. Inclusion of
this
Motion Detector on Wireless Controller menu allows remote
turn-on of connected modules when the detector is triggered.
The Motion Detector is designed with include ambient light level and sensitivity
adjustments , in order to fulfill the purpose of security and home automation.
When the detector is cooperated with security appliances, it is acting
as a security device by detecting changes in infra-red radiation levels. If a person
moves within or across the device field of vision, a trigger radio signal will be
transmitted to cause full alarm condition in order to frighten intruders away.
Alternatively, when the detector is worked with home automation appliances, the
detector can be set to perform the role of home automation device by detecting
both changes in infra-red radiation levels and percentage of lux levels. Once night
falls,the percentage of ambient illumination is lower than preset value. If a person
moves within or across the device field of vision, a trigger radio signal will be
transmitted so as to turn on the connected lightings for better illumination.
The PIR Detector adopts a CR123A , 3.0V Lithium battery which under normal
conditions will have typical life in excess of 1 year. When the battery level drops
to an unacceptable level, device will notify backgroune. When this occurs the
batteries should be replaced as soon as possible.
