Natural Gas Alarm
ML-310CE Series
User’s Manual
This manual has been prepared for the ML-310CE Series
Gas Alarm (“Gas Alarm”), which is designed for use only in
areas serviced by Consolidated Edison Co. of New York,
Inc. (“Con Edison”). Within these areas, Con Edison is
handling installation, troubleshooting, replacement and
disposal of Gas Alarms. 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 an Itron Network Solutions
(INS) communications module designed to automatically
send information directly to Con Edison 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.
• Do NOT re-enter until told to do so by
authorities.
DANGER: ELECTROCUTION
Do not subject the Gas Alarm to water or liquid by
submerging it, spraying liquid on it or otherwise.
Do not disassemble.
DANGER: EXPLOSION
This Gas Alarm is designed to act as a continuous
monitor of natural gas that reaches the sensor.
This Gas Alarm should not be used as a short-
term testing device to perform a onetime check
for the presence of natural gas, as plugging the
battery into the device in the presence of natural
gas may cause an explosion.
DANGER: FIRE AND EXPLOSION
Improper disposal may result in fire or explosion.
Contact Con Edison to arrange for disposal.
DANGER: HAZARDOUS CONDITIONS
Follow these instructions completely. Failure to
do so may result in an undetected natural gas leak
or other hazardous conditions that may cause
serious injury or death.
DANGER: HEARING DAMAGE
Do not place your ear directly against or in close
proximity to the Gas Alarm when it is alarming.
Such exposure to the audible gas leak alarm may
damage your hearing.
WARNING
• Do not change the Gas Alarm’s installation position,
relocate it from where it is installed, or tamper with the
Gas Alarm or its battery.
• Do not block, cover, obstruct or paint over the Gas Alarm
or its sensor. The Gas Alarm can only detect natural gas
that reaches its sensor.
• Network or power outages may prevent Con Edison from
receiving or processing automated notifications from your
Gas Alarm, including notifications related to gas leak
alarms. Always follow these instructions, without relying
on such automated notifications.
• This Gas Alarm will reach its end-of-service-life in
approximately 6 years from the date of installation.
Contact Con Edison for replacement if you observe the
end-of-service-life alarm indicator LED.
• Do not modify, disassemble, submerge, strike, crush, or
expose the Gas Alarm to high levels of volatile organic
compounds. Doing so may cause the Gas Alarm to
malfunction.
• Commercially available batteries will not work with the
Gas Alarm. Contact Con Edison to arrange for
replacement.
• Keep out of reach of children.
• For indoor use only.
NOTICE
• The Gas Alarm must only be installed by Con Edison or
an authorized Con Edison contractor.
• The Gas Alarm only detects natural gas. It does not
detect carbon monoxide, fire, heat, smoke, flames,
propane or any other gas.
• The Gas Alarm is not a substitute for proper installation,
use, and maintenance of natural gas appliances and
piping systems. The Gas Alarm does not prevent natural
gas leaks from occurring, nor can it eliminate any existing
natural gas leaks or problems.
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 Con Edison 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 INS communications module, the Gas Alarm is
designed to automatically send Gas Alarm-related
information to Con Edison. 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 Con
Edison. The Gas Alarm is also designed to send information
about device health to Con Edison during automated health
checks performed every 8 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 Con Edison 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 INS communications module is
also designed to send an automated notification to Con
Edison 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. When activated,
the gas leak alarm is designed to:
Beep 4 times and state “Danger – gas leakexplosion
risk –evacuate, then call 911.” This notification will
repeat every 6 seconds for 4 minutes, and then every 1
minute thereafter.
Send a gas leak alarm notification to Con Edison via
the INS communications module every 30 seconds.
Flash the Red LED light once every 2 seconds.
DANGER: EXPLOSION, FIRE AND
ASPHYXIATION
