Mini Smoke Detector (Mini-SD-ZBS)
The Mini SD-ZBS Mini Smoke Detector is a ZigBee Smoke and Heat Detector, it is capable of sending wireless signals to the coordinator in the
ZigBee network upon detection of smoke particles or abnormal high heat to protect house from fire hazards. The Mini Smoke Detector’s alarm
situations, battery condition, operating conditions, supervisory data and general fault information are sent to the ZigBee Control Panel wirelessly.
The Mini Smoke Detector also features IR detection. The it detects infrared signature to pick up movements within an assigned area and signals
the Control Panel to activate the alarm if an intruder crosses its’ path of detection.
The Mini Smoke Detector 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 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 Mini Smoke Detector 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 Mini Smoke Detector.

alarm is activated, the Mini Smoke Detector will transmit alarm signal and raise alarm with its built in buzzer, the Red LED will flash
rapidly. The alarm sound will repeat in pattern of 3-second alarm and 1-second pause.
Smoke Detection:
The Alarm is activated whenever the smoke concentration exceeds the detection threshold.
The Mini Smoke Detector will check some concentration every 8 seconds, the alarm will continue until the smoke concentration
drops below alarm threshold.
Heat Detection:
Rate of Rise: When the temperature rises by 8.25°C per minute.
High Heat: When the temperature exceeds 57.3°C
The Mini Smoke Detector will check temperature every 10 seconds. It will only stop alarming if the temperature drops below alarm
threshold:
If the alarm was triggered by Rate of Rise condition (8.25°C per minute or more): The temperature must drop to 4°C below highest
temperature detected for the Detector to stop alarming.
If the alarm was triggered by High Heat condition (57.3°C): The temperature must drop below 49°C for Mini Smoke Detector to
stop alarming.
For both Smoke alarm and Heat Alarm, a restore signal will be transmitted if no smoke is detected again for 160 seconds.

ZigBee Network Setup
ZigBee Device Guideline
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.
Joining the ZigBee Network
As a ZigBee device, the Mini Smoke Detector needs to join a ZigBee network to transmit signal when smoke concentration or temperature
is detected. Please follow the steps bellow to join the Mini Smoke Detector into ZigBee network.
The Mini Smoke Detector has 3 ZigBee Endpoints for PIR, Smoke Detector and Temperature Sensor function. When joining ZigBee network,
it will be recognized as 3 separate ZigBee devices and will occupy 3 zones in your ZigBee network coordinator.
1. Insert the battery into the battery compartment to power on the Mini Smoke Detector.
2. The Mini Smoke Detector will emit 2 short beeps, and begin warm up for 1minute, LED flashes every 2 seconds.
3. After 1-minute warm up period expires, the Mini Smoke Detector will emit a beep to indicate it now enters calibration process. The
calibration process takes 1~7 minutes; the LED will continue to flash during calibration. Joining ZigBee network is prohibited during
warm up calibration process. After calibration process the Mini Smoke Detector will emit a 2-tone beep, LED will turn off.
4. The Mini Smoke Detector is only available for joining the ZigBee network 3 minutes after completing calibration
Press and hold the Test Button for 10 seconds and release to search for existing ZigBee network. Please make sure the permit-to-join
feature on the router or coordinator of your ZigBee network is enabled.
5. After joining the ZigBee network, the Mini Smoke Detector will be registered in the network automatically. Please check the ZigBee
coordinator, security system control panel or CIE (Control and Indicating Equipment) to confirm if joining and registration is successful.
6. When calibration is complete, the Mini Smoke Detector will emit 2 beeps and LED will stop flashing to indicate it is now under normal
operation. If calibration fails, the Mini Smoke Detector will sound continuous beep.
7. Under normal operation, if the Mini Smoke Detector loses connection to its current ZigBee network, the LED indicator will flash every 20
minutes to indicate the situation. Please check your ZigBee network condition and Mini Smoke Detector signal range to correct the
situation.
Removing Device from ZigBee Network (Factory Reset)
To remove the Mini Smoke Detector from current ZigBee network, the device must be put to Factory Reset to complete
device removal. Factory Reset function will clear the Mini Smoke Detector of its stored setting information and prompt the
device to search for new ZigBee network.
Before removing device, make sure the Mini Smoke Detector is within current ZigBee network signal range
1. Delete the Smoke Detector from current control panel / CIE.
2. The Mini Smoke Detector can only be reset within 3 minutes after power up. If it has been powered up for more than 3
minutes, remove and reinsert the batteries.
3. Press and hold the function button for 10 seconds, then release the button to reset Smoke Detector.
4. Upon reset, the Smoke Detector will clear current ZigBee network setting and transmit signal to ZigBee coordinator to
remove itself from current ZigBee network. It will then actively search for available ZigBee network again and join the
network automatically.
