Carbon Monoxide Detector Installation

ACV-Triangle Tube requires the installation of a mini-
mum of two (2) hard wired carbon monoxide detectors
with an alarm and battery back-up in the mechanical
room where the Prestige Excellence is located and an-
other installed in the living area outside the bedroom(s)
