CO-8ZBS Carbon Monoxide Detector
Introduction
CO-8ZBS is a ZigBee Carbon Monoxide Detector. It is capable of sending wireless signals to the
coordinator in the ZigBee network upon detection of Carbon Monoxide concentration.
The Carbon Monoxide 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 Carbon Monoxide 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 Carbon Monoxide Detector.
Parts Identification
1. Dual Color LED indicator (Amber/Red)
The LED indicator lights up in the following conditions:
- Red LED flashes twice
The Carbon Monoxide Detector has successfully joined a
ZigBee network.
- Red LED Flashes once every 20 minutes:
The Carbon Monoxide Detector has lost connection to its
current ZigBee network.
- Amber LED flashes every second:
The Carbon Monoxide Detector is in Alarm Silence mode.
2. Function Button
- Press the button once to send a supervision signal.
- Press the button once during alarm to silence the alarm.
- Press and hold the button for 10 seconds then release to reset
the Carbon Monoxide Detector.
3. Battery Compartment
The Carbon Monoxide Detector is powered by three
AA Alkaline 1.5V batteries.

 The Carbon Monoxide Detector will be activated according to the following table when CO
concentration is detected.
CO concentration
level
Time taken before
alarming
30 ppm None
50 ppm 60-90 minutes
100 ppm 10-40 minutes
300 ppm Under 3 minutes
 Once the CO concentration level exceeds the threshold and persists for the time length as
listed in the above table, the Carbon Monoxide Detector will transmit the signal to ZigBee
network coordinator and raise alarm with its built-in siren.
 After the alarm has been activated, the Carbon Monoxide Detector will continue to send the
alarm signal every 2 minutes as long as CO concentration remains above 30 ppm.
 If the CO concentration drops below 30 ppm, the Carbon Monoxide Detector will stop alarming
and transmit a restore signal
