1. Introduction
Netvox Z311E, an asset tag for monitoring in a security system, acts as an End Device in a ZigBee network. It does not perform permit-join function as a coordinator or a router for other devices to join the network. Z311E is featured to play a role of the sensor (Zone device) in the ZigBee security system. It is for installing on an object. When the object is moved, Z311E will notify the central security unit, CIE (Control and Indicating Equipment) device, to send commands to a siren device to trigger an alarm.
What is ZigBee?
ZigBee is a short-range wireless transmission technology based on IEEE802.15.4 standard and supports multiple network topologies such as point-to-point, point-to-multipoint, and mesh networks. It is defined for a general-purpose, cost-effective, low-power-consumption, low-data-rate, and easy-to-install wireless solution for industrial control, embedded sensing, medical data collection, smoke and intruder warning, building automation and home automation, etc.
2. Product Appearance
The Netvox Z311E Wireless Asset Tag is shown from multiple angles. One view displays the main unit, a white rectangular tag with rounded corners, featuring a large circular button on the front and the 'netvox' logo. An indicator light (Red/Green) is positioned above the button. Another view shows the back of a protective casing, which appears to be a small white box with a clasp. A small circular sensor, labeled 'Light Sensor', is visible on the main unit. The side of the main unit shows two distinct buttons labeled 'Binding Key' and 'Auxiliary Key'.

5. Setting up Z311E
5-1. Turn On/ Turn Off Z311E
Under the circumstances Z311E is first time used or after resetting, when it is powered on and cannot successfully search a network, Z311E will go into turn-off mode.
To manually turn on or turn off Z311E, please use the following instructions:
Turn it on:
Press the Binding Key once. The indicators will flash red once, and the device is ready to be used.
Turn it off:
Press the Binding Key. The indicator will flash red 10 times within 5 seconds. Press the Binding Key again within the 10 red flashes to turn the device off.
5-2. Join the ZigBee Network
After Z311E is turned on, it will search for an existing ZigBee network and send a request to join the network automatically. While Z311E is under the coverage from a coordinator or a router whose permit-join feature is enabled, Z311E will be permitted to join the network.
- Enable the permit-join function (valid for 60 seconds) of a coordinator or a router (please refer to the user manual of the coordinator or the router to enable the permit-join feature).
- Turn on Z311E. It will start to search and join the network.
- The indicator will flash green once when it finds out a network to join.
- The indicator will flash green 5 times after it is joined successfully. Otherwise, the indicator will not flash.
5.3. Enroll in the ZigBee Security System
Z311E is a Zone device in the ZigBee security system. Right after Z311E joins the ZigBee network, it will automatically find out a CIE (Control and Indicating Equipment) device (i.e. Netvox Z201B) and send a registration request to the CIE device to enroll in the security system. The enrollment has these 3 situations:
- A. There is no CIE device or no compatible CIE device in the network → the indicator flashes red twice.
- B. There is a compatible CIE device in the network, but it is failed to enroll → the indicator flashes red 4 times. Users can press the Auxiliary Key to initiate the registration.
- C. The enrollment is completed → the indicator flashes red 6 times.
NOTE: Users had better NOT enroll multiple Zone devices at the same time to prevent registration failure.
Operation Modes
5-4. Sleeping Mode
Z311E is designed to go into sleeping mode for power-saving in some situations:
- A. While the device is in the network → the sleeping period is 5 minutes; it will wake up every 5 minutes to keep online.
- B. When it doesn't find a network to join → Z311E will go to sleeping mode. It will wake up every 15 minutes to search a network to join.
- C. Once Z311E was joined to a network and by any chance the network is no longer existed or the device is out of the network → Z311E will wake up every 15 minutes to find the network it joined before.
It never keeps in sleeping mode and continues to find out a network every 15 minutes. This condition would consume up to 30 times power spending compared to normal-operating status. To prevent this unwanted power consumption, we recommend that users remove the batteries to power off the device.
5-5. Wake up Z311E
When users would like to setup or acquire data from the device which is in sleeping mode, we have to wake up the device as the following steps:
- Press and hold both Binding Key and Auxiliary Key.
- Release the keys after the indicator flashes red twice.
- The indicator will flash green 5 times when Z311E is online.
- Z311E will broadcast the device data to the ZigBee network.
Z311E would be in active status for 2 minutes for communication.
5-6. Asset Tag
- Z311E's Zone Type: Vibration/Movement sensor (ID: 0x002D)
- The value of Alarm1 is 1 when the vibration/movement is detected.
- The value of Alarm2 is 1 when the environmental illumination is changed.
Under the circumstances that Z311E has enrolled to the security system, it will send the warning command to the command center after the vibration/movement is detected. The Warning Device will send out alarm sound or lighting alert for warning. Z311E will also send the warning command to the command center when the environmental illumination is changed.
Under the circumstances that Z311E hasn't enrolled to the security system, it will try enroll in a security system after triggering. After the enrollment, Z311E will send the warning command to the command center.
After any button is applied, the vibration/movement/lighting sensing features will be disabled for 20 seconds.
5.7. HeartBeat Technique
In a security system, it is important that Zone devices report the conditions to the central security unit (the CIE device). To meet this need, Netvox came up with a technique called "HeartBeat".
Right after Z311E enrolls to a security system, it sends a HeartBeat signal to the CIE device. Afterward, it will send HeartBeat data every hour by default settings.
