Instruction Sheet

In general, install combination Smoke, 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 smoke, natural 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 6).
Not suitable for installation in hazardous locations as defined in the 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.
BASIC SAFETY INFORMATION
• This combination Smoke, Carbon Monoxide and Natural Gas alarm has separate alarms. This
alarm is not designed to detect any other gas. Carbon monoxide and natural gas may be
present in other areas. The Smoke, CO and Natural Gas Alarm will only indicate the presence
of CO or natural gas which reaches the sensor.
• Do not paint the alarm. Paint may clog the openings to the sensing chambers and prevent the
unit from operating properly.
• Do not stand too close to the unit when the alarm 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.
Do not install this alarm into an electrical circuit controlled by a dimmer or switch or
ground fault circuit interrupter.
