Hush Condition: The red LED will flash every 10 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 sec-
tion 6 for low battery information).
WHEN UNITS ARE INTERCONNECTED, only the red LED of the
alarm “which senses the smoke” or “is being tested” (the originat-
ing unit) will flash rapidly. All other units in the interconnect system
will sound an alarm but their red LED’s will NOT flash rapidly.
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. In an
interconnected installation all interconnected alarms should sound
when the test button on any one of the interconnected alarm is
pressed. 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.
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).
NOTE: WEEKLY TESTING IS REQUIRED.
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.
The Model PI2010 has a “HUSH” control that is extremely use-
ful in a kitchen area or other areas prone to nuisance alarms. For
