The Siterwell LoRaWAN CO alarm detects and alerts to the presence of carbon monoxide (CO) gas within your smart building environment in order to prevent potentially lethal carbon monoxide poisoning.

In addition to the alarm alert sound, the sensor also features the following visual status indicators:

  • Alarm Indicator: Red LED – used to indicate to the presence of CO
  • Fault Indicator: Yellow LED – used to indicate the fault warning status of the alarm
  • Power Indicator: Green LED – used to indicate power status (will flash every 30 seconds)
