light see the section, “Trouble-Shooting Guide” in the User’s
Manual for this alarm provided in the Owner’s Information
Package.
This alarm will operate normally down to 7-volt DC. It will
not work without power.
CO Alarm
The red CO LED will flash and the alarm will sound 4
“BEEPS” then silent for 5 seconds. These signals indicate that
the CO level is over 70 ppm. IMMEDIATE ACTION IS
REQUIRED. This cycle will continue until the TEST/Mute
button on the front of the alarm is pressed. Ventilate the
Camper. The red light will stay on until the CO has cleared, or
the alarm will reactivate in approximately 6 minutes if the CO
is still present. DO NOT RE-ENTER THE CAMPER. This
alarm will return to normal operation after the Camper’s
properly ventilated.
The CO (Carbon Monoxide) detector is designed to detect
carbon monoxide from any source of combustion. It is NOT
designed to detect smoke, fire, or any other gases.
Procedures to Take During a CO Alarm:
Actuation of this device indicates the presence of the carbon
monoxide (CO) or propane gases, can cause death. If signal
sounds (4 beeps and flashing or solid red light), immediately
turn off all combustion sources and ventilate the premises.
Evacuate the premises immediately. Check that all persons are
accounted for. Do not re-enter the camper until it has been
aired out and the problem corrected. Get the system checked
before restarting appliances.
Carbon monoxide cannot be seen or smelled and Breathing it
in can cause unconsciousness or death.
Propane Gas Alarm
The Red LED will flash and the alarm will sound a steady
tone whenever a dangerous level of propane or methane gas is
detected. IMMEDIATE ACTION IS REQUIRED. The
detector will continue to alarm until the Test/Mute switch on
the front of the alarm is pressed. Ventilate the Camper. The
RED Gas LED will continue to flash until the gas is cleared,
or the gas alarm will reactivate in approximately 5 minutes if
the gas is still present. DO NOT RE-ENTER THE CAMPER.
This alarm will return to normal operation after the Camper is
properly ventilated.
NOTE: This detector senses propane gas in the air, not smoke
or fire or other gases. It detects the presence of propane gas at
the sensor; explosive gas may be present in other areas.
DO NOT attempt to repair the detector. If it fails the test,
check the battery voltage and if it still does not function
properly, replace the entire unit.
Procedures to Take During a Gas Alarm
Turn the propane off at the tank(s), turn off all propane
appliances, extinguish all flames and smoking material and
open all doors and major windows to air out the camper. Do
not re-enter the camper until the alarm stops sounding. If the
alarm sounds a second time after the propane is turned back
on, leave the propane off and have a Nücamp RV Service
Center make the necessary repairs to the source of the propane
leak.
Be aware of the difference between a propane leak versus
propane escaping from an unlit, open burner. Pure propane
from a leaking pipe or fitting is heavier than air and will build
up its heaviest concentration at the floor level first. Propane
from open burners is intentionally mixed with air to induce
burning and will dissipate into the air. The primary purpose of
the detector is to detect propane leaks. The propane from open
burners is mixed with air (oxygen) so that it will burn. When
mixed with air, the propane becomes only marginally heavier
than air and may not sink to the floor. If a burner is left on, the
area around the burner, range and adjoining counter space will
be combustible and will cause injury and damage if ignited.
This condition may exist for an extended period before the
propane can reach the detector’s location and be detected. The
detector only indicates the presence of propane at the sensor.
Propane may be present in other areas.
The detector is powered by the 12-volt DC system and is
always powered if the camper is connected to the truck, a
charged battery, or 120-volt AC power. The fuse for the
detector is in the Power Distribution Center.
NOTE: The detector is continuously powered; disconnect the
battery if you are not using your camper. The detector can
evidentially drain the camper battery.
Backup Camera
The backup camera (optional) is located beside roof ladder on
the rear wall, it is a color camera with a built-in microphone.
Switch location is below the wardrobe door right inside the
entry door, it's a double toggle switch with the one on the right
being the camera switch. The portable monitor that will be in
the truck cab has a 12-volt power plug and a built-in receiver.
Electrical System
The electrical system consists of a primary 12-volt DC system
and a 120-volt AC system. The 12-volt system uses battery
power like that used in automobiles. The 120-volt system
requires a source of 120-volt power provided through the
power supply cord or optional generator. These systems are
