The Simplex 4098-9770 is a TrueAlarm addressable CO sensor base that adds carbon monoxide sensing to a TrueAlarm sensor location while using only one IDNet address. It holds an electrolytic CO sensing module alongside a TrueAlarm sensor head (ordered separately) and is powered from the IDNet channel, so existing base locations can be upgraded without new wiring.
