Occupant Safety
Combination Carbon Monoxide (CO) /
Propane (LP) Alarm
The combination alarm contains two independent, self-cleaning
electronic sensors designed to sense the presence of carbon
monoxide (CO) and propane gas. When the LED on the front
glows green, the alarm is active.
The gas sensor may also detect other combustible fumes or
vapors including; acetone, alcohol, butane and gasoline. These
chemicals can be found in common items such as deodorant,
cologne, perfume, wine, liquor, adhesive, lacquer, kerosene,
most cleaning agents and the propellants of aerosol cans.
High temperatures can activate glue and adhesive vapors. If
your RV is closed on a hot day, the chemicals used in its con-
struction may be detected, even months after the vehicle was
built.

& Outgassing, and Formaldehyde

Combination Alarm Operation
To be operational, the combination alarm MUST have power
supplied by the RV's 12-volt electrical system. The alarm will
operate normally down to 7-volts DC. DO NOT allow the auxiliary
battery to fall below 7-volts DC.
• Simultaneous CO and Propane Alarms - If both CO
and propane gas are detected at the same time:
◦
The combination alarm will give higher priority to the
propane alert. A gas explosion is the more immediate
potential danger.
◦
The propane LED will flash red and the beep will
sound. The CO LED will remain a steady red until
the RV is ventilated.
• The CO sensor requires a ten (10) minute initial warm-up
period to clean the sensor and achieve stabilization.
◦
The warm-up period is indicated by the CO LED
blinking green.
During the warm-up period the
unit cannot go into a CO alarm
.
◦
After the warm-up period, the green LED should glow
continuously. If the LED is not lit please refer to the
troubleshooting section, and contact your dealer for
assistance.
This combination alarm
will not work without
power; it is wired directly
to the RV's 12-volt electrical
system. Continual power
is supplied by the auxiliary
battery. If a battery cable
is disconnected at the
terminal, this alarm will
not work.
This alarm may not
alarm at low CO levels.
Individuals with medical
problems may consider
using warning devices,
which provide audible
and visual signals for CO
concentrations under
30 ppm.
This alarm may not
be heard.
The alarm’s
loudness is designed to
meet or exceed regulatory
standards; however, the
alarm may not be heard
if alarms are located
in remote locations or
behind closed doors.
Persons who are hard-of-
hearing, have consumed
alcoholic beverages,
taken prescription, non-
prescription or illegal
drugs, may not hear the
alarm.
This alarm will only
indicate the presence
of gas at the sensor.
CO or explosive propane/
natural gas may be present
in other areas. Do not block
or cover the alarm with any
object that can prevent
a gas leak or carbon
monoxide from reaching
the sensor.
