Description
The CO sensor of the Intelligent CO / Low Frequency Sounder Base is an electrochemical sensor with three levels of carbon monoxide detection and a life of approximately six years, in normal environmental conditions. The CO sensor is fully supervised and provides a signal for field replacement at the end of its life cycle. Without removing the base from the ceiling, the CO sensor module (45681-801) can be replaced by simply unplugging the expired module and plugging in a new one.
