O-9-EL-ZBS is wireless temperature sensor with attached temperature probe. It can automatically or
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
Remove the cover by loosening the bottom fixing screw, the inside of the Temperature Sensor will be
revealed as shown.
1. External Temperature Probe Terminal
Connect the External Temperature Probe to this Terminal
2. Tamper Switch
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
Connect the Probe to External Temperature Probe Terminal

 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.
