NEWCOSMOS 807NLR Natural Gas Alarm
This manual has been prepared for the 807NLR Gas Alarm (“Gas Alarm”). If you
have a Gas Alarm installed in your house or building, you should read and
understand the important instructions and warnings contained in this manual
and retain a copy for future reference. When natural gas, which consists
primarily of methane, is present at concentrations of 10% or greater of the
lower explosive limit (LEL) for methane, the Gas Alarm is designed to activate
a gas leak alarm. The gas leak alarm consists of a flashing red LED light, an
audible warning sound (a loud beep), and a recorded message. The Gas Alarm is
equipped with a LoRa communications module designed to automatically send
information directly to your gas utility. including information associated
with gas leak alarm activation, Gas Alarm error, low battery, and end-of-
service-life.
DANGER: EXPLOSION, FIRE AND ASPHYXIATION
Natural gas leak alarm indicates an emergency situation and risk of explosion.
- EVACUATE IMMEDIATELY and take others with you.
- Do NOT use a phone, light a match, or turn on or off any light switches, flashlights, or appliances. Doing so could IGNITE a FIRE or EXPLOSION.
- CALL 911 once you are safely outside the premises.

General Description and Intended Use
DANGER
If you smell natural gas, evacuate the area immediately, then call 911. Do not
wait for the gas leak alarm to sound or for your gas utility to receive an
automated notification.
This Gas Alarm is designed to detect natural gas. Natural gas is a fossil fuel
that is primarily made up of methane. It is commonly used for cooking, home
heating and water heating. Natural gas is typically supplied through a gas
main and utility service line connected to your home. Natural gas is odorless
and colorless, but has a chemical odorant (mercaptan) added to it to give it a
distinct “rotten eggs” smell. Even odorized natural gas may not be detected by
smell in an unoccupied space, by an individual with reduced sensitivity to
smell, or in other situations. Natural gas is a highly flammable chemical
compound. Although it happens rarely, a natural gas leak can occur inside a
house or building. This can be dangerous because it increases risk of
explosion and fire. The Gas Alarm is designed to activate a gas leak alarm
when it detects 10% or greater of the LEL for methane, which is 0.5% or
greater of methane in air. When the gas leak alarm activates, the Gas Alarm
will beep 4 times and state “Danger – gas leak explosion risk – evacuate, then
call 911.” In the event of a gas leak, you may smell natural gas before the
gas leak alarm is activated. If you smell natural gas at any time, do not wait
for the gas leak alarm to sound or check for Gas Alarm malfunction. Evacuate
immediately, then call 911. Using the LoRa communications module, the Gas
Alarm is designed to automatically send Gas Alarm-related information to your
gas utility. When natural gas is detected at or above the gas leak alarm
threshold, the Gas Alarm is designed to transmit a gas leak alarm notification
to your gas utility. The Gas Alarm is also designed to send information about
device health to your gas utility during automated health checks performed
every 24 hours. The Gas Alarm is not guaranteed to prevent personal injuries
or property damage associated with a gas leak. For example, an error may occur
that prevents detection of natural gas, including gas leaks. Network or power
outages may prevent your gas utility from receiving or processing automated
notifications from your Gas Alarm, including notifications related to gas leak
alarms. Some people may sleep through and not hear the audible gas leak alarm.
You should ensure that your natural gas appliances and piping systems are
properly installed, used, and maintained to reduce the likelihood of a natural
gas leak.
Gas Alarm parts
Gas Alarm functions
The Gas Alarm is designed to activate an audible gas leak alarm in the event
of a natural gas leak, and a silent alarm with visual LED indicators in the
event of a Gas Alarm error, a low-battery condition, and when the Gas Alarm
reaches its end-of-service-life. The LoRa communications module is also
designed to send an automated notification to your gas utility when any of
these alarms activate.
Natural gas leak alarm activation
The Gas Alarm is designed to activate a gas leak alarm when it detects natural
gas at a concentration that reaches or exceeds 10% of the LEL for methane.

Troubleshooting Guide
This Gas Alarm is designed to be troubleshot exclusively by authorized
professionals. This guide is intended for professional use only.
Testing the detector
- CAUTION
If the Gas Alarm does not operate properly, it cannot alert the presence of natural gas. Take immediate action if the Gas Alarm fails a test.
Testing power
Press test button until you hear a “Beep” sound, then quickly release (within
3 seconds after pressing the test button). If the device is properly powered,
the green LED will flash twice every second (for 3 seconds) to indicate that
the power is on.
Testing gas leak alarm notifications
Press test button until you hear a “Beep” sound, then continue to hold until
you hear a “Beep Beep” sound approximately 5 seconds later. Release within 10
seconds of pressing the test button.”Beep” ”Beep Beep”
When the button is Released “Beep Beep Beep Beep Danger –Gas leak explosion
risk – evacuate, the call 911.” Will sound twice.
If the Gas Alarm is operating properly, the red LED will flash once every 2
seconds for a 12 second period, and the following alarm message will sound
twice: “Beep Beep Beep Beep Danger – gas leak explosion risk – evacuate, then
call 911.”
Testing automated communications
Press and hold test button for at least 10 seconds, until you have heard a
single “Beep” followed by a double beep (“Beep Beep”) followed by a triple
beep (“Beep Beep Beep”). This will enable communications test mode, and the
green LED will flash 3 times per second for as long as you are in
communications test mode. Once in communications test mode, press the test button
additional times to test whether the detector is communicating normally with
your gas utility’s systems, able to properly transmit detector error signals,
and able to properly transmit a low battery signal. Success will be indicated
as follows:
| Green LED| Yellow LED
---|---|---
Communications test mode activated| Flashes 3x per second| Off
1st press: normal communication| Flashes 2x per second| Off
2nd press: proper transmission of device error signal| Flashes 2x per
second| Flashes 3x per second
3rd press: proper transmission of low battery signal| Flashes 2x per second|
Flashes 2x per second
If the red LED light activates or the alarm sounds during any of these tests,
the detector’s communication functions are not working properly. Additional
