1. Smoke Alarm: What To Do When the Alarm Sounds
The smoke alarm pattern is three long beeps with voice “Fire! Fire!” repeating. The red LED blinks in sync with beep
pattern.
The smoke alarm takes precedence when both smoke and carbon monoxide are present.
•Alert small children in the home as well as anyone else that might have difficulty recognizing the
importance of the alarm sounding or that might have difficulty leaving the area without help.
•Leave immediately by your escape plan. Every second counts, so don’t waste time getting dressed or
picking up valuables.
•While leaving, don’t open any inside door without first feeling its surface. If hot, or if you see smoke seeping
through cracks, don’t open that door! Instead, use your alternate exit. If the inside of the door is cool, place
your shoulder against it, open it slightly and be ready to slam it shut if heat and smoke rush in.
•If the escape route requires you to go through smoke, stay close to the floor where the air is cleaner. Crawl if
necessary, and breathe shallowly through a cloth, wet if possible.
•Once outside, go to your selected meeting place and make sure everyone is there.
•Call the fire brigade from your mobile phone outside, or from your neighbor’s home-not from yours!
•Don’t return to your home until the fire officials say that it is all right to do so.
NOTE: See Section RECOGNIZING NUISANCE ALARMS, for nuisance alarm situations.

2. Carbon Monoxide Alarm: What To Do When the Alarm Sounds
The carbon monoxide (CO) alarm pattern is four quick beeps with voice “Warning! Carbon Monoxide” repeating
every 5 seconds. The red LED blinks in sync with beep pattern.
WARNING: CARBON MONOXIDE ALARM ACTIVATION INDICATES THE PRESENCE OF CARBON
MONOXIDE CO AT HIGH CONCENTRATIONS WHICH CAN KILL YOU.
Based on recommendations from EN50292, follow these steps if alarm sounds:
1. Keep calm and open all doors and windows. Turn off all fuel-burning appliances if possible. Note: it is possible
that outdoor conditions could influence domestic CO alarms (bad traffic pollution in cold weather, for
example). In these circumstances, the level of indoor CO might actually increase when doors and windows
are opened.
2. If the alarm continues to sound, even after being reset (where appropriate), then evacuate the premises,
alerting other occupants to the risk. Leave doors and windows open. Do not re-enter the premises.
3. Get medical help for anyone suffering the effects of CO poisoning, and advise that CO inhalation is
suspected.
4. Call Gas Emergency Services: 0800 111 999, or your local Gas Safe Registered Engineer:
PHONE NUMBER:
Never restart the source of the CO problem until it has been corrected.
Never ignore the sound of the alarm!
NOTE: See Section RECOGNIZING NUISANCE ALARMS, for nuisance alarm situations.

This alarm detects products of combustion using photoelectric technology, and carbon monoxide using an
electrochemical cell. Many times throughout this User Guide, we will refer to Carbon Monoxide as “CO.”
Ten (10) years after the unit was installed, this unit will automatically alert you that it is time to replace the unit.
This is called “End of Unit Life” mode. See Troubleshooting Guide. To help track the life of your alarm, write
the installation date in the space provided on the side of the alarm. A label has provided that has important
information on what to do in case of a CO alarm. Place the label at eye level on a wall near the alarm after it is
mounted.

6. Limitations of Smoke and CO Alarms
WARNING: PLEASE READ CAREFULLY AND THOROUGHLY
LIMITATIONS OF SMOKE ALARMS
•Life safety from fire in residential occupancies is based primarily on early notification to occupants of the
need to escape, followed by the appropriate egress actions by those occupants.
•Fire warning systems for dwelling units are capable of protecting about half of the occupants in potentially
fatal fires. An alarm may not be effective in some situations, such as during incendiary fires where the fire
grows so rapidly that an occupant’s egress is blocked even with properly located alarms, or when victims
are intimate with the fire (for example, when a person’s clothes catch fire while cooking), too old or young,
or physically or mentally impaired such that they cannot escape even when warned early enough that
escape should be possible. For these people, additional strategies such as protection-in-place or assisted
escape or rescue are necessary.
•A battery powered alarm must have a battery of the specified type, in good condition and installed
properly.
•Smoke alarms must be tested regularly to make sure the battery and the alarm circuits are in good operating
condition.
•Smoke alarms cannot provide an alarm if smoke does not reach the alarm. Therefore, smoke alarms may not
sense fires starting in chimneys, walls, on roofs, on the other side of a closed door or on a different floor.
•If the alarm is located outside the bedroom or on a different floor, it may not wake up a sound sleeper.
•The use of alcohol or drugs may also impair one’s ability to hear the smoke alarm. For maximum protection,
a smoke alarm should be installed in each sleeping area on every level of a home.
•Although a system of smoke, heat, and CO alarms can help save lives by providing an early warning of a fire,
they are not a substitute for an insurance policy. Home owners and renters should have adequate insurance
to protect their lives and property.
•There are situations where an alarm may not be effective to protect against fire. For instance:
a) smoking in bed
b) leaving children home alone
c) cleaning with flammable liquids, such as petrol
This alarm is not intended to alert hearing impaired individuals.
