Basic Safety Information - Universal Security Instruments MCN400 Manual

Natural gas (methane) is typically supplied through a main utility line connected to your home.
Early warning is best achieved by the installation of alarms on all floors and areas of the
household.
WHERE THIS ALARM SHOULD BE INSTALLED
• Install an alarm inside each bedroom where the occupant closes the door while sleeping.
• An alarm should be installed in any family living unit containing a fuel-burning appliance or
fireplace or having an attached garage.
• An alarm should be centrally located outside of each separate sleeping area in the immediate
vicinity of the bedrooms. Where bedrooms are separated and audibility of the alarm to
occupants within the bedroom area could be seriously impaired, more than one alarm could be
needed.
In general, install combination CO and Gas Alarms:
• WHERE YOU CAN HEAR THE ALARM FROM ALL SLEEPING AREAS.
• In or near bedrooms and living areas or wherever you suspect a gas or CO exposure is likely.
• On each level of a multilevel home.
IMPORTANT!
Installation in an improper location can affect the sensitive electronic components in this alarm.
Please review WHERE THIS ALARM SHOULD NOT BE INSTALLED (see Page 3).
Not suitable for installation in hazardous locations as defined in the NFPA 70, National Electrical
Code. This alarm will detect natural gas primarily and carbon monoxide secondarily. Natural gas
events will always take precedence over carbon monoxide events. The word "gas" will be used to
specifically refer to natural gas.
When on AC power, this alarm is designed to act as a continuous monitor. It is not designed for
use as a short-term testing device to perform a quick check for the presence of CO or gas.
• This combination Carbon Monoxide and Natural Gas alarm has two separate alarms. This alarm
is not designed to detect fire or any other gas. Carbon monoxide and natural gas may be
present in other areas. The CO and Natural Gas Alarm will only indicate the presence of CO or
natural gas which reaches the sensor. The CO and Natural Gas Alarm is not designed to sense
smoke, heat or flames.
• Do not paint the alarm. Paint may clog the openings to the sensing chambers and prevent the
alarm from operating properly.
• Do not stand too close to the alarm when it is sounding. It is loud to wake you in an emergency.
Exposure to the horn at close range may harm your hearing.
Make sure the alarm is not receiving excessively noisy power. Examples of noisy power
could be major appliances on the same circuit, power from a generator or solar power, light
dimmer on the same circuit or mounted near fluorescent lighting. Excessively noisy power
may cause damage to your alarm.
This alarm cannot be operated from power derived from a square wave, modified square wave or
modified sine wave inverter. These types of inverters are sometimes used to supply power in off-grid
installations, such as solar or wind derived power sources. These power sources may produce high
peak voltages which will damage the alarm.
This alarm should receive continuous electrical power. The battery is meant for emergency
backup only. Choose an outlet where it can't be accidentally unplugged or switched off
by children. Keep small children away from the unit. Teach them not to play with it or
unplug it. Explain what the different alarm sounds mean.
Do not plug this alarm into an outlet controlled by a dimmer or switch or ground fault
circuit interrupter.
The test sequence lasts for approximately 3 seconds after the test button is pressed and
released. The alarm will then test itself for proper operation. When testing the alarm, have
someone else check that the alarm can be heard easily from the sleeping areas. The alarm should
be located where it can wake you if it alarms at night.
