The Tamper Protection is only active after power on the Temperature Sensor for 5 minutes.
The Temperature Sensor is protected by a tamper switch which is compressed against the
mounting surface when mounted. Whenever the Temperature Sensor is removed from mounted
location, the tamper switch will be activated and the Temperature Sensor will send a tamper
open signal to remind the user of the condition.

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.
Due to the fundamental structure of ZigBee network, ZigBee device will actively seek and join network
after powering on. Since performing a task in connecting network may consume some power, it is
required to follow the instructions to avoid draining battery of a ZigBee device
- Ensure your ZigBee network router or coordinator is powered on before inserting battery into the
ZigBee device.
- Ensure the ZigBee network router or coordinator is powered on and within range while a ZigBee
device is in use.
- Do not remove a ZigBee device from the ZigBee network router or coordinator without removing the
battery from a ZigBee device.

As a ZigBee device, the Temperature Sensor needs to join a ZigBee network to transmit temperature
signal. Please follow the steps bellow to join the Temperature Sensor into the ZigBee network.
1. Insert the battery into the battery compartment to power on the Temperature Sensor
2. After powering up, press and hold the learn button for 10 seconds as the Siren resets and starts
searching for existing ZigBee network. Please make sure the permit-to-join feature on the router or
coordinator of your ZigBee network is enabled.
3. If the Temperature Sensor successfully joins a ZigBee network, the LED Indicator will flash twice to
confirm.
4. After joining the ZigBee network, the Temperature Sensor will be registered in the network
automatically. Please check your ZigBee coordinator, system control panel or CIE (Control and
Indicating Equipment) to confirm if joining and registration is successful.
5. After joining the ZigBee network, if the Temperature Sensor loses connection with current ZigBee
network, the LED will flash every 20 minutes to indicate. Please check your ZigBee network
condition and Temperature Sensor signal range to correct the situation.

If you want to remove the Temperature Sensor from current network and join a new network, you need
to use the Factory Reset function to clear the Temperature Sensor for its stored setting and information
first before it can join another network. To perform Factory Reset:
1. Press and hold the learn button for 10 seconds, release the button when the LED flashes once.
2. The Temperature Sensor has been reset to factory default setting with all its previous network
information removed. It will now actively search for available ZigBee network again and join the
network automatically.
3. If the Temperature Sensor successfully joins a ZigBee network, the LED Indicator will flash twice.
