O-9-EL-ZBS is wireless temperature sensor with attached temperature probe. It can automatically or
TTSSO
manually transmits temperature condition to the coordinator in the ZigBee Network.
The Temperature Sensor 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 Temperature Sensor 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 Temperature Sensor.
Parts Identification

The Tamper switch will be activated when the Temperature
Sensor is removed from mounted surface.
3. Internal LED
Flashes – when the Learn Button is pressed.
Flashes twice – when successfully joined a ZigBee network.
Flashes once every 20 minutes – lost connection to its current
ZigBee network.
4. Learn Button
Press the button once to transmit a test / temperature signal to
the ZigBee coordinator.
Press and hold the button for 10 seconds then release to reset the Temperature Sensor.
5. Battery Compartment
6. External Temperature Probe

Features
TTeemmppeerraattuurree DDeetteeccttiioonn
The Temperature Sensor will transmit temperature signals to the ZigBee coordinator in every 10
minutes regularly.
If Temperature Sensor fails to receive acknowledgment from the Control Panel, it means that
Temperature Sensor has lost connection to the ZigBee coordinator, please check you ZigBee
coordinator condition.
When the temperature changes by +/- 2˚C, the Temperature Sensor will also transmit a signal.
You can also press the Function Button once to transmit a temperature signal manually.
The temperature detection range is about -30°C ~ 100°C ( -22°F ~ 212°F).
The Temperature Sensor uses one CR123 - 3V Lithium battery. Please always replace battery with
the correct size and voltage. When the Temperature Sensor is in low battery status, a low battery
signal will be sent to notify the user.

Battery Change
1. Remove the Cover by loosening the bottom fixing screw.
2. Remove the Old Battery.
3. Press the Tamper Switch or the Learn Button a few times.
4. Fit a new battery into the battery compartment. Please orient the battery according to the
correct polarity.
5. Replace the Cover.

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 Network Setup
ZZiiggBBeeee DDeevviiccee GGuuiiddeelliinnee
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.

There are two ways to mount the Temperature Sensor, by either Self-adhesive installation or Screw
mounting.
Self adhesive mounting
1. Clean the surface with a suitable degreaser.
2. Remove the protective covering from one side of the double-sided adhesive pad and firmly
apply to the back of the device.
3. Next remove the other cover and firmly press the item onto the desired location.
Do not use the adhesive pad method of installation on a surface with peeling or cracked
paint, or on a rough surface.
Screw mounting
The Base has two knockouts, where the plastic is thinner, for mounting purpose.
To mount the Temperature Sensor
1. Remove the cover
2. Break through the knockouts on the base
3. Using the holes as a template, drill holes in the surface
4. Insert the wall plugs if fixing into plaster or brick
5. Screw the base into the wall plugs
6. Screw the cover back on to its base
IMPORTANT NOTE
If the Temperature Sensor installation location is away from your system control panel and requires
ZigBee routers to improve signal strength. DO NOT use a ZigBee Router without backup battery. A
ZigBee router without battery will be powered down during AC power failure and the Temperature
Sensor connected to the router will lose connection with ZigBee network. You should plan your
Temperature Sensor installation location using only ZigBee router with backup battery.
