First Alert Model GCO1 is a 120V AC plug-in with battery back-up single station
carbon monoxide and explosive gas (propane and natural/methane) combination
alarm specifically designed for residential and institutional applications including
sleeping rooms of hospitals, hotels, motels, dormitories, and other multifamily
dwellings as defined in standard NFPA 101. Model GCO1 has been fully tested
and complies with, UL1484, UL2034 and other agencies that model their codes
after the above agencies. It meets building codes where 120V AC plug-in digital
display with battery back-up carbon monoxide and explosive gas combination
alarms are required.
First Alert Model GCO1 is a state of the art carbon monoxide and explosive gas
combination alarm designed to provide early warning of a carbon monoxide,
propane or methane gas danger. It features an advanced electrochemical CO
sensor and a metal oxide explosive gas sensor with an EZ view backlit digital
display. It plugs in easily into any standard 120V AC outlet. The line cord allows
for convenient mounting options where methane requires unit to be mounted up
high and propane should be mounted low. Carbon monoxide mounting location is
not height sensitive as CO disperses evenly throughout the house. The peak level
function allows for easy viewing of highest gas levels detected. It has a 9V
alkaline battery backup, an End of Life feature and single button test/silence.
This alarm has two silence features. Low Battery Silence: Temporarily silence the
low battery chirp for up to eight hours. Alarm Silence: Silence alarm for several
minutes. The End of Life timer provides audible and visual notice when alarm
needs to be replaced. Battery installation and removal can occur while the unit is
mounted to the wall or plugged into the electrical outlet via the swing up battery
cover. Includes mounting anchors and screws.
