the unit has defective batteries or other failure. DONOT use an open flame to test your alarm, you
could damage the alarm or ignite combustible materials and start a structure fire.
TEST THE ALARM WEEKLY TO ENSURE PROPER OPERATION. Erratic or low sound coming from
your alarm may indicate a defective alarm, and it should be returned for service (see Section 12).
5.NUISANCE ALARMS
Smoke alarms are designed to minimize nuisance alarms. Cigarette smoke will not normally set off the
alarm, unless the smoke is blown directly into the alarm. Combustion particles from cooking may set
off the alarm if the alarm is located close to the cooking area. Large quantities of combustible particles
are generated from spills or when broiling. Using the fan on a range hood which vents to the outside
(non-recirculating type) will also help remove these combustible products from the kitchen.
Model PI2000 has a “HUSH” control that is extremely useful in a kitchen area or other areas prone to
nuisance alarms. For more information refer to Section 4, OPERATION AND TESTING.
If the alarm does sound, check for fires first. If a fire is discovered, get out and call the fire department.
If no fire is present, check to see if one of the reasons listed in Section 2 may have caused the alarm.
6.MAINTENANCE
ALARM REMOVAL
IF TAMPER RESIST FEATURE HAS BEEN ACTIVATED, REFER TO TAMPER RESIST FEATURE
DESCRIPTION IN SECTION 3 FOR REMOVAL INSTRUCTIONS.
To replace the battery, remove the alarm from the trim ring by rotating the alarm in the direction of the
“OFF” arrow on the cover. To disconnect the A.C. power harness, squeeze the locking arms on the
sides of the Quick Connector while pulling the connector away from the bottom of the alarm (see
Section 3, Figure 2)
BATTERY INSTALLATION AND REMOVAL
To replace or install the batteries you must first remove the alarm from the trim ring by following the
ALARM REMOVAL instructions at the beginning of this section. After alarm has been removed , you
can open the battery door and install or replace the battery. Battery installation instructions are
provided on the inside of the battery door.
When installing the battery, press the battery reminder finger down into the battery compartment and
install the battery (see Figure 5).
CAUTION! IF THE BATTERY REMINDER FINGER IS NOT HELD DOWN IN THE BATTERY
COMPARTMENT BY THE BATTERY, THE BATTERY DOOR WILL NOT CLOSE, THE A.C. QUICK
CONNECTOR WILL NOT ATTACH TO THE ALARM, AND THE ALARM WILL NOT ATTACH TO THE
TRIM RING.

FIGURE 5
This smoke alarm uses a 9V alkaline battery (a lithium battery may also be used). A fresh alkaline bat-
tery should last for one year under normal operating conditions.
This alarm has a low battery monitor circuit which will cause the alarm to “chirp’” approximately every
30 - 40 seconds for a minimum of seven (7) days when the battery gets low. Replace the battery
when this condition occurs.
USE ONLY THE FOLLOWING 9 VOLT BATTERIES FOR SMOKE ALARM REPLACEMENT.
Alkaline type EVEREADY 522; DURACELL MX 1604, MN1604; GOLD PEAK 1604A
Lithium type ULTRALIFE U9VL
After installing or changing the battery, reinstall your alarm. Test your alarm by using the test button and
check that the green LED is on.
NOTE: REGULAR TESTING IS REQUIRED.
CLEANING YOUR ALARM: YOUR ALARM SHOULD BE CLEANED AT LEAST ONCE A YEAR
To clean your alarm, remove it from the mounting bracket as outlined in the beginning of this section.
You can clean the interior of your alarm (sensing chamber) by using compressed air or a vacuum
cleaner hose and blowing or vacuuming through the openings around the perimeter of the alarm. The
outside of the alarm can be wiped with a damp cloth. After cleaning, reinstall your alarm and test your
alarm by using the test button. If cleaning does not restore the alarm to normal operation the alarm
should be replaced. After cleaning, reinstall your alarm. Test your alarm by using the test button and
check that the green LED is on.
7.LIMITATIONS OF SMOKE ALARMS
WARNING: PLEASE READ CAREFULLY AND THOROUGHLY
•NFPA 72 states: 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 occu-
pants. Fire warning systems for dwelling units are capable of protecting about half of the occupants
in potentially fatal fires. Victims are often intimate with the fire, 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, other strategies such as protection-in-place or assisted
escape or rescue are necessary.
•Smoke alarms are devices that can provide early warning of possible fires at a reasonable cost;
however, alarms have sensing limitations. Ionization type alarms offer a broad range of fire sensing
capabilities but are better at detecting fast flaming fires than slow smoldering fires. Photoelectric
alarms sense smoldering fires better than flaming fires. Home fires develop in different ways and are
often unpredictable. Neither type of alarm (photoelectric or ionization) is always best, and a
given alarm may not always provide warning of a fire.
•A battery powered alarm must have a battery of the specified type, in good condition and installed
properly.
•A.C. powered alarms will not operate if the A.C. power has been cut off, such as by an electrical fire
or an open fuse.
•Smoke alarms must be tested regularly to make sure the batteries and the alarm circuits are in good
operating condition.
