PRESIDIO
Propane Gas is heavier than air and will settle to the lowest point which is generally the floor of
the motorhome. The detector is also sensitive to other fumes such as hair spray of which most
contain butane as the propellant. Butane, like propane gas, is heavier than air and will settle to
the floor level where it will be detected. When this occurs, press the reset button to stop the
alert sound for 60 seconds.
Other combustibles which will be detected include alcohol, liquor, deodorants, colognes,
perfumes, wine, adhesives, lacquer, kerosene, gasoline, glues, most of all cleaning agents and
the propellant's of aerosol cans. Most are lighter than air in their vapor state and will only be
detected when the coach is closed up. Glues and adhesives may exhaust hydrocarbon vapors
for months after they are applied. They are easily activated by high temperatures.
The Propane Gas Detector is powered by the motorhome coach batteries and/or the inverter.
The detector will operate properly until the battery is drained down to 10 volts (a low battery
condition is 10.4 volts). If the power source (battery and/or inverter) is disconnected, or if the
power is otherwise interrupted, the detector will not operate.
The Propane Gas Detector has a self check circuit which runs at all times when the detector is
powered. In the event that the circuitry fails, a failure alarm will sound. It is a continuous series
of short beep tones between long intervals and is distinctively different from the alert sound.
New Coach Odor:
The glues and other materials used in manufacturing the motorhome produce vapors which
may be detected when the coach is closed up on a warm day. Air out the motorhome
thoroughly.
Continuous Beeping: The gas detector beeps about once every minute, even when it is turned
off. The problem is a weak battery in the smoke detector which causes the smoke detector to
produce short beeps which sound similar to the alert sound of the Propane Gas Detector.
This is a high pitch tone and bounces off the walls, making its location very hard to pinpoint. If
the sound is not coming from the Propane Gas Detector identify the source and refer to the
sources section in this manual for means of repair.
Aerosol Activates the Detector: Most aerosol hair sprays use butane gas as the propellant.
Butane, like propane gas, is heavier than air and will settle to the floor level where it will be
detected. The detector is doing its job as butane is combustible.
Other Gases: Other gases which can cause the detector to respond with an alert include the
vapors from any fuel, liquor, alcohol, deodorants, colognes, perfumes, wine, adhesives, lacquer,
and most cleaning agents.
