This product is designed to detect products of combustion
using the ionization technique. It contains 0.9 microcurie
of Americium 241, a radioactive material. Distributed under
U.S. NRC License No. 32-23858-01E. Manufactured in
compliance with U.S. NRC safety criteria in 10 CFR 32.27.
The purchaser is exempt from any regulatory
requirements.
This smoke alarm uses an extremely small amount of
radioactive element in the ionization sensor chamber. Do
not try to repair the smoke alarm yourself. Refer to the
instructions in
Warranty
for service.
The smoke alarm is operating once the alarm is activated
(see
Activation
) and testing is complete. When the smoke
alarm ionization sensor chamber senses products of
combustion, the horn will sound a loud (85db) alarm until
the sensing chamber is cleared of smoke particles.
False Alarms
Smoke alarms are designed to minimize false 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
that vents to the outside (non-recirculating type) will also
help remove these combustible particles from the kitchen.
