PIR Motion Sensor
Introduction
IR models are ZigBee passive infrared motion sensors (PIR) with optional pet-immune function. It is capable of
sending wireless signals to the coordinator in the ZigBee network upon movement detection.
The PIR is designed to give a typical detection range of 12 meters when mounted at 2 meters above ground.
The pet immune model (IRP-9ZBSSL) has a pet-immune range of 7 meters and will not trigger false alarm from
you household pets within this distance. The PIR also has tamper protections switch which will be activate upon
any attempt of unauthorized cover opening or removal from mounted surface.
The PIR utilizes ZigBee technology for wireless signal transmission. ZigBee is a wireless communication
protocol that is reliable and has low power consumption and high transmission efficiency. Based on the
IEEE802.15.4 standard, ZigBee allows a large amount of devices to be included in a network and coordinated
for data exchange and signal transmission
The PIR serves as an end device in the ZigBee network. It can be included in the ZigBee network to transmit
signal upon activation, but cannot permit any other ZigBee device to join the network through the PIR.
Parts Identification
1. Function Button aka LED indicator
The Function Button also doubles as the LED Indicator. The function button
is used to control the PIR. The LED indicator is used to indicate PIR status.
LED Indication:
The LED indicator lights up in the following conditions:
- Flashes twice quickly:
The PIR has successfully joined a ZigBee network after factory reset.
- Flashes once every 20 minutes:
The PIR has lost connection to its current ZigBee network.
- Flashes under normal operation
The PIR has detected a movement and it is currently under Low
Battery or Tamper open condition.
Function Button Usage:
- Press the button once to send a supervision signal and enter Test
Mode.
- Press and hold the button for 10 seconds then release to reset the PIR.
2. Battery Insulator
3. Battery Compartment
The PIR is powered by one 3V Lithium battery.
4. Tamper Switch
The Tamper switch will be activated when the PIR cover is
opened.
5. Sensitivity Increaser Jumper Switch (JP2)
- If the jumper is OFF (jumper link is removed or “parked” on one pin),
the PIR detection sensitivity is in normal level
(Factory Default)
- If the jumper is ON (jumper link parked on 2 pins), the PIR’s detection
sensitivity is high.

The PIR has a “
sleep time
” of approximately 30 seconds to conserve power. After transmitting a detected
movement, the PIR will not retransmit detection signal for the next 30 seconds. After 30 seconds, the PIR
will return to normal operation and begin transmitting detection signal again. This way continuous
movement in front of a PIR will not unduly exhaust the battery.

After each movement detection, if 30 second passes without another detection, the PIR will transmit a
“motion stop” signal to ZigBee network coordinator.
