6NookBox Installation Guide Dome PIR Motion Sensor (IRD-23 / IRD-23SL)
Installation Guideline
• The PIR is designed to be mounted on the ceiling
• When mounted at 2.7 meter height, the PIR provides detection coverage of a 360° circle wth approximately 6meter diameter.
• When mounted at 4 meter height, the PIR provides detection coverage of a 360° circle wth approximately 8meter diameter.
• For optimal performance, rotate the PIR so that the intruder would move across its detection area from side to side.
<NOTE>
To nd out the “sides” of the PIR. Hold the PIR with LED indicator pointing upward, and the left and right sides of the PIR are considered the PIR’s sides. The PIR
sensor is most sensitive when the intruder is moving from one side to the other.
• Refer to the diagrams below for more information.
• It is recommended to install the PIR in the following locations.
• In an ceiling area with full view of its detection coverage unobstructed by appliances and furniture.
• Near the entrance of a room or house to monitor entry activity.
• Limitations
• If a door is already protected by a Door Contact, do not install the PIR too close to the Door. If the Door Contac and the PIR is
triggered and transmit signal at the same time, the signals may collide and cancel each other.
• Do not install the PIR exposed to direct sunlight.
• Avoid installing the PIR in areas where devices may cause rapid change of temperature in the detection area, i.e. air conditioner,
heaters, etc.
• Avoid large obstacles in the detection area.
• Do not pointing directly at sources of heat e.g. Fires or boilers, and not above radiators.
• Avoid moving objects in the detection area i.e. curtain, wall hanging etc.
• After the installation site is selected, follow the steps below to mount the PIR.
• Press the Test Button to enter Test Mode. Walk around the protected area noting when the LED lights up and check that the detection
coverage is adequate.
• When detection coverage is found to be satisfying, installation is now completed.
