Installation Guide

2NookBox Installation Guide Dome PIR Motion Sensor (IRD-23 / IRD-23SL)
The Dome PIR Motion Sensor is designed to be mounted on the ceiling to provide a 360 detection
coverage without blind spots to pick up movements within an assigned area and signals the Control
Panel to activate the alarm if an intruder crosses its’ path of detection.
The PIR consists of a two-part design made up of a PIR main body and a back cover for wall mounting.
The main body contains all the electronics and optics and the base provides a means of installation.
The PIR main body has an anti-sabotage tamper switch which will be activated when the main body is
removed from the back cover to prevent unauthorized access and removal from the mounting surface.
The PIR can also alert you to signal communication problems and low battery situations.
The Dome PIR includes 2 models:
IRD-23: Powered by 2 AA alkaline 1.5V batteries
IRD-23SL: Powered by 1 CR123A lithium 3V battery

Identifying the parts
1. Test Button aka LED indicator
The test button and also doubles as the LED indicator. The test button is used for
testing the radio performance and for learning purpose. The LED indicator is used
to indicate the status of system.
2. IR Sensor
3. Sensitivity Increaser Jumper Switch (JP3)
It is a 2-pin jumper switch.
4. Tamper Switch
The Tamper switch protects the PIR from removal from mounted location.
5. Battery Compartment
IRD-23: 2 AA alkaline 1.5V batteries.
IRD-23SL: 1 CR123A lithium 3V battery
6. Mounting Holes
7. Hooks
8. Ceiling Mounting Knockouts (Inside)
Jumper On
If the jumper is ON, the PIR’s
detection sensitivity is high.
Jumper O
If the jumper is OFF (if the jumper link is removed
or “parked” on one pin), the the PIR’s detection
sensitivity is in normal level. (Factory default)

LED Indicator
In Normal operation mode, the LED Indicator will not light except in the following situations:
• When the PIR is in low battery condition, every time it transmits a detected movement, the LED will light up for about 2 seconds.
• When the cover is opened and the tamper switch is violated, the LED will light up for 2 sec. to indicate it is transmitting the
“Tamper” signal.
• When the Tamper condition persists, every time it transmits a detected movement, the LED will light up.
• When if the PIR is in Test mode, the LED will light up every time a movement is detected.
Sleep Timer
The PIR has a “sleep time” of approximately 1 minute to conserve power. After transmitting a detected movement, the PIR will not retransmit
for 1 minute; any further movement detected during this sleep period will extend the sleep time by another minute. In this way continuous
movement in front of a PIR will not unduly exhaust the battery.
Supervision Function
The PIR is transmits a supervisory signal once every 30 to 50 minutes. If the Control Panel fails to receive the Supervisory signals transmitted
from a certain PIR for a preset time, an “Out-Of-Order” fault message will be generated.
Sensitivity Increaser Function
You can use the sensitivity increaser function to increase the IR’s detection sensitivity. To increase detection sensitivity, please set JP3 Jumper
to ON position. To maintain the normal detection sensitivity, set the JP3 Jumper to OFF position (factory default).
Test mode
The PIR can be put into Test mode by pressing the Test Button aka LED on the front cover. In Test mode, it will disable the sleep timer and will
enable the LED indicator to ash every time a movement is detected. Each time press the Test Button, the PIR will transmit a test signal to the
Control Panel for radio range test and enter the test mode for 3 mins. It will exit Test Mode automatically after 3 mins and returns to normal
mode.

Battery
The PIR uses dierent batteries depending on the PIR Model:
• IRD-23: 2 AA alkaline 1.5V batteries
• IRD-23SL: 1 CR123A lithium 3V battery
The batteries are included in the package. The PIR feature low battery detection function. A low battery signal will be sent to the Control
Panel along with regular signal transmissions for the Control Panel to display the status accordingly.
<NOTE>
When changing batteries, after removing the old batteries, press the Tamper Switch twice to fully discharge before inserting new batteries.
Tamper Switch
The PIR has a tamper switch located on the back of the PIR main body. When the PIR is properly installed on the back cover, the tamper switch
will be compressed. When the PIR is removed from the back cover, the tamper switch will be activated and trigger the PIR to send a tamper
open signal to the Control Panel.
Getting Started
• Insert the battery into the battery compartment.
• The LED indicator steadily ashes for 30 seconds. (The PIR is warming up). During the warming period, the PIR will not be activated.
It is recommended that you stay away from the detection area during this time. After the warming period is over, the light will turn o
and the PIR will be ready for operation.
• Put the Control Panel into learning mode, refer to Control Panel manual for detail.
• Press the learn/test button on the front cover.
• If the Control Panel receives PIR signal, it will display the information accordingly, refer to Control Panel manual to complete the
learning process.
• After the PIR is learnt-in, put the Control Panel into “Walk Test” mode, hold the PIR in the desired location, and press the Test button
to conrm this location is within signal range of the Control Panel.
• When you are satised that the PIR work in the chosen location, you can proceed with installation.

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.

Mounting Method
• The PIR is designed to be mounted on the ceiling
• The back cover has 4 knockouts where the plastic is thinner for ceiling mounting.
• After nishing PIR learning and walk test, proceed to mount the PIR according to instructions below
I. Break through the 4 knockouts on inside of back cover
II. Use the knockout hoes as template, drill holes in the ceiling, insert wall plug if required.
III. Screw the back cover onto the ceiling according to drilled holes.
IV. The back cover has numbers on the insides to mark the mounting hole number, which corresponds to the mounting hook
number on the back of main body. Align the mounting hole with the mounting hook when installing. Refer to gure below
for mounting hook and hole location.
V. Install the PIR main body onto the back cover. Fit the hooks on the back cover to the mounting holes on PIR main body.
VI. Rotate the PIR main body clockwise to lock the hooks into the mounting hole. Refer to gure below.
VII. PIR mounting is now complete.
