CRAWLER TRC 458, User Manual, Page: 9 / 77

Low Voltage
The operating voltage for the detector is 12 VDC. The actual voltage supplied to
the detector in a recreational vehicle may drop below the minimum 8 VDC. The
detector provides the user with a low voltage warning before reaching that level
and will provide additional distinct, clear warnings and alarms after the 8 VDC
level is reached. However, if available power supplied to the unit is below the
operating voltage of 8 VDC, the detector will not detect gas or provide protection
against dangerous levels of LPG.
NOTE
If the low voltage warning sounds, the detector will need to be reset by disconne-
cting the battery, before normal operation will occur.
Warning
Activation of this detector indicates the possible presence of LPG, which can
cause an explosion and/or fire, causing serious injury or death. This normally
indicates a leak in the LPG installation or an LPG appliance. Extinguish all open
flames, open your windows and door, and evacuate the unit immediately. Do not
activate any electrical switch. Turn off the LPG at your gas tank(s). Do not re-enter
your unit until a qualified repair technician has corrected the problem and certi-
fied the system as safe.
Warning
It is not recommended that the detector be disconnected from the battery
during periods of storage. There is a small heater on the sensor of the device
that burns away impurities in the air during periods of normal use. During periods
when power is interrupted, impurities can build up on the sensor. When power is
returned to the detector, the detector alarm may activate until the impurities are
burned off. This could take a number of hours, during which time the alarm will be
constantly on.
Warning
Failure to replace this product by the “REPLACE BY DATE” printed on the alarm
may result in death by Carbon Monoxide poisoning. Replace By Date is five (5)
years from the date of manufacture.
Warning
Activation of your Carbon Monoxide alarm’s audible horn indicates the presence
of Carbon Monoxide that can kill you. Leave the area immediately!
Warning
This product is intended for use in ordinary, indoor locations of family living units.
It is not designed to measure compliance with occupational safety and health
administration (OSHA) commercial or industrial standards. Individuals who are
at special risk from Carbon Monoxide exposure by reason of age, pregnancy, or
medical condition may consider using warning devices which provide audible
and visual signals for Carbon Monoxide concentration under 30 ppm. If in doubt,
consult your medical practitioner.
