SAFETY
RV Safe 12 Volt Propane Leak Detector Operation
(Model: RVLP-2B)
This article provides basic operation instructions for a RV Safe 12 Volt Propane Leak Detector (Model: RVLP-2B).
Liquified petroleum (LP) gas is commonly called propane
and is used as fuel for heating and cooking appliances,
especially for RV’s. Propane gas is explosive at the lower-
explosive-limit (LEL), which is 21,000 parts per million
(ppm). RV Safe will alarm at 10% LEL, or 2,100 ppm.
Propane gas is denser than air, and will usually
accumulate close to the floor. Therefore, RV Safe should
be placed near the floor in order to quickly detect
propane gas leaks.
RV Safe includes an 85dB audible horn, two LEDs, and
a Silence/Test button. The chart below summarizes the
alarm outputs in each state.

The green power LED is ON when the alarm is functioning
normally and no CO or propane gas is present. Press
the Silence/Test button to perform a self test and enter
the Test State. Note: Supply current will remain higher
for 30 seconds after power-up. Alarm will not detect CO
or Propane for the first 30 seconds and will draw extra
current.
If no LEDS are on, then the alarm is powered off. Apply
power to the alarm to resume normal operation.
If the Silence/Test button is pressed while in normal
operation, the alarm will perform a self test of the
CO sensor, propane sensor and battery voltage. It is
recommended to perform a self test weekly, after power up
from storage, and before each trip. If the self test passes,
the alarm will perform 2 cycles of the CO horn pattern (4
rapid chirps followed by a 4 second pause), followed by 2
cycles of the propane horn pattern (constantly beeping).
If propane gas exceeds 10% of the lower-explosive-limit for
more than 30 seconds, the alarm will enter propane alarm
state. The horn will sound with constant beeps and the red
LED will be on. Immediately turn off all propane appliances
and gas valve at the propane tanks. Open doors and
windows to properly ventilate the RV. Check for any gas
leaks and contact a qualified RV technician to diagnose
possible propane leaks. The alarm may be silence for 5
minutes by pressing the Silence/Test button.
A CO alarm or propane alarm can be silenced for up to 5
minutes by pressing the Silence/Test button. The red LED
will flash each second while the alarm is silenced. The
original alarm state will resume after 5 minutes if the CO or
propane levels still exceed safe levels.
If the supply voltage drops below 8VDC, the alarm will
enter Low Battery State. The horn will chirp every minute
and both LEDs will flash every minute. Alarm performance
cannot be guaranteed as the supply voltage drops below
the low battery threshold. Charge or replace the RV battery
immediately. Do NOT disconnect the alarm.
If the CO or propane alarm fails a self test, or if the End-of-
Life is reached (after 5 years of operation), the alarm will
enter the Failure State. The horn will chirp every minute
and both LEDs will do a double flash every minute. Replace
the alarm immediately.
