Propane/Carbon Monoxide Detector
Any recreational vehicle which contains a propane fuel system with
propane consuming appliances requires a propane leak detection device
for safety. Currently this detector also serves as a carbon monoxide
protection device. A converter or auxiliary battery is required to supply
12-volt DC power to operate the device. There is no master cut-off switch
to disengage the detector.
What is Carbon Monoxide?
Carbon Monoxide (CO) is a highly poisonous gas which is released when
fuels are burned. It is invisible, has no smell and is therefore very difficult
to detect with the human senses. Under normal conditions, in a room
where fuel burning appliances are well maintained and correctly
ventilated, the amount of carbon monoxide released into the room by
appliances is not dangerous. These fuels include: wood, coal, charcoal,
oil, natural gas, gasoline, kerosene, and propane. Such gases can build
up in the blood, interfering with the body’s ability to supply oxygen to itself.
Because CO is a colorless, odorless, tasteless, and highly poisonous gas
that prevents the blood from carrying oxygen to vital organs, CO is 200
times more likely to replace oxygen in the blood. It can endanger lives
even at low levels of concentration.
Dual Sensor Technology
The SAFE-T-ALERT 35 and 25 series combination CO/Propane Gas
Alarm is an alarm that combines into a single, compact system a powerful
alarm that detects both Carbon Monoxide (CO) and propane (LPG).
The 35 and 25 series uses the latest microprocessor technology
combined with two electronic self-cleaning sensors that operate
independently of each other. The combined unit can detect CO and
propane simultaneously.
Operation
When the unit is first powered up, the CO sensor requires a ten (10)
minute initial warm-up period to clean the sensor element and achieve
stabilization. The GREEN LED indicator will flash on and off during the
10 minute warm-up period. The unit cannot go into a CO alarm during the
warm-up period. To test your unit during the warm-up period, press the
test button. See Test Procedure in this manual. After the warm-up period,
the GREEN power on indicator should glow continuously. If the on
indicator does not light, see the section, Trouble-shooting Guide, in the
user’s manual for further information. DO NOT attempt to fix it yourself.
Gas Alarm
When you power the alarm, it has a warm-up period of approximately 1
minute. This unit cannot go into a gas alarm during the warm-up period.
After 1 minute the alarm can detect explosive gas and will energize the
relay on models 35-742-R and 35-742-R-MS.
