Disconnect AC power before changing battery. Shock hazard exists if AC power is miswired.
The alarm uses a 9 Volt battery. The battery should last for at least one year under normal
operating conditions. The alarm has a low battery indicator, an audible beep or chirp. It will operate
at approx. 40 second intervals for a minimum of 7 days. When this indication occurs, replace the
battery with an Alkaline type (Energizer #522, Duracell #MN1604, Zeus 9V), or Lithium type
(Energizer LA522, Ultralife U9VL-J, U9VL-J-P) from your local retailer.
OPTIONAL BATTERY DRAWER TAMPER LOCKING PIN: To make your battery drawer tamper
resistant, a locking pin has been provided (breakaway part on mounting bracket).
NOTE: If this feature has been activated, you will need to deactivate it by removing the battery
drawer tamper pin located at side of battery drawer. Refer to Page 7.
Pull the QUICK DRAW
push the replacement battery into the battery drawer until it is held securely in place. Carefully close
the battery drawer and reinstall the tamper pin.
Test the alarm by pushing the TEST button on the alarm cover until the alarm sounds, then release.
SMOKE, CO AND NATURAL GAS ALARM LIMITATIONS
Alarms have limitations. Like any other electronic device, Smoke, CO and Natural Gas alarms are
not foolproof.
Smoke, CO and Natural Gas alarms have a limited operational life. Your alarm must be tested
weekly, because it could fail to operate at any time. If your Alarm fails to test properly, or if its self-
diagnostic test reveals a malfunction, immediately have the unit replaced (see last page for warranty
information).
Smoke, CO and Natural Gas alarms can only sense CO which reaches the alarm's sensor. Carbon
monoxide may be present in other areas without reaching the alarm.
CO or gas could be present on one level of the home and not reach the alarm installed on a different
level. For example, CO or gas in the basement may not reach an alarm on the second level, near
the bedrooms. For this reason, we recommend you provide complete coverage by placing a Smoke,
CO and Natural Gas alarm on every level of the home.
Smoke, CO and Natural Gas alarms are not a substitute for property, disability, life or other insurance
of any kind. Appropriate coverage is your responsibility.
POTENTIAL SOURCES OF CO IN THE HOME
Fuel-burning appliances, such as; heaters, gas or wood burning fireplaces, gas kitchen ranges
or cooktops, gas clothes dryers.
Damaged or insufficient venting; such as; corroded or disconnected water heaters, vent pipes,
leaking chimneys, pipes or flues or cracked heat exchangers, blocked or clogged chimney openings.
Improper use of appliances/devices; operating a barbeque grill or vehicle in an enclosed area
(such as a garage or screened porch).
Transient CO Problems: "transient" or on-again/off-again CO problems can be caused by outdoor
conditions and other special circumstances.
The following conditions can result in transient CO situations:
1. Excessive spillage or reverse venting of fuel-burning appliances caused by outdoor ambient
conditions, such as:
• Wind direction and/or velocity, including high gusts of wind. Heavy air in the vent pipes (cold/
humid air with extended periods between cycles).
• Negative pressure differential resulting from the use of exhaust fans.
