4. OPERATION AND TESTING

OPERATION: The smoke alarm is operating once a fresh battery is installed and testing is complete.
When products of combustion are sensed, the unit sounds a loud (85db) temporal alarm until the air is
cleared.
HUSH CONTROL: The "HUSH" feature has the capability of temporarily desensitizing the alarm circuit
for approximately 10 minutes. This feature is to be used only when a known alarm condition, such as
smoke from cooking activates the alarm. The smoke alarm is desensitized by pushing the "HUSH" but-
ton on the smoke alarm cover. If the smoke is not too dense, the alarm will silence immediately and the
red LED will flash every 2 seconds for approximately 10 minutes. This indicates that the alarm is in a
temporarily desensitized condition. The smoke alarm will automatically reset after approximately 10
minutes, and sound the alarm if smoke is still present. The "HUSH" feature can be used repeatedly
until the air has been cleared of the condition causing the alarm. Pushing the test/reset button on the
alarm will end the hush period.
NOTE: DENSE SMOKE WILL OVERRIDE THE HUSH CONTROL FEATURE AND SOUND A
CONTINUOUS ALARM.
CAUTION: BEFORE USING THE ALARM HUSH FEATURE, IDENTIFY THE SOURCE OF THE
SMOKE AND BE CERTAIN A SAFE CONDITION EXISTS.
LED INDICATOR: This smoke alarm is equipped with a red LED indicator. The red LED is located
under the test button and has several modes of operation.
Standby Condition The red LED will flash every 30-40 seconds to indicate that the smoke
alarm is operating properly.
Alarm Condition When the alarm senses products of combustion and goes into alarm,
the red LED will flash rapidly (one every two seconds). The rapid flashing
LED and temporal alarm will continue until the air is cleared.
Hush Condition The red LED will flash every 2 seconds as long as the alarm is in Hush
mode.
Low Battery Condition The red LED flash will be accompanied by an audible chirp. Replace the
battery when this condition occurs.
SMOKE SENSING CHAMBER OPERATION: This alarm will "chirp" if any of the components in the
smoke sensing chamber fail. This chirp will occur between the flashes of the red LED indicator light. (If
the chirp occurs at the same time as the red LED flash, see Section 6 for low battery information.)
TESTING: Test by pushing the test button on the cover and hold it down for a minimum of 5 seconds.
This will sound the alarm if the electronic circuitry and horn and battery are working. If no alarm
sounds, the unit has defective batteries or other failure. DO NOT use an open flame to test your alarm,
you could damage the alarm or ignite combustible materials and start a structure fire.
Alarm Memory This smoke alarm is equipped with an alarm memory feature which
produces a rapid chirping sound when the test button is pushed. This
sound indicates that the alarm has been activated since it was last tested.
Releasing the test button clears the memory. If the alarm memory sound is
heard, release the test button and press the test button again to enter the
normal test mode.
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.
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.
The model PI 9000 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.
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.

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 Section 3, Figure 3).
CAUTION! IF THE BATTERY REMINDER FINGER IS NOT HELD DOWN IN THE BATTERY
COMPARTMENT BY THE BATTERY, THE BATTERY DOOR WILL NOT CLOSE AND THE ALARM
WILL NOT ATTACH TO THE TRIM RING.
This smoke alarm uses a 9V alkaline battery (a lithium battery may also be used). A fresh alkaline
battery 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.
NOTE: REGULAR TESTING IS RECOMMENDED.
WARNING! USE ONLY THE BATTERIES SPECIFIED. USE OF DIFFERENT BATTERIES MAY HAVE A
DETRIMENTAL EFFECT ON THE SMOKE ALARM.
