Carbon monoxide co monitor and alarm system intec
It is a high end commercial grade unit made in the USA.
This unit was intended for use in a multi unit installation but was never installed. It is in as new condition and functions perfectly.
I will include the proper 24 volt power supply as well. Can be used in a home or a commercial environment. It is very easy to install and use.
This unit retails for $1,998.00 U.S.
Below is a link to the PDF of the operating and installation instructions.
