Description:
Photoelectric technology is generally more sensitive than ionization
technology at detecting large particles, which tend to be produced in
greater a mounts by smoldering fires , which may smolder for hours before
bursting into flame . Sources of these fires may include cigarettes .
The unit monitors the air, and when smoke re aches its sensing chamber, it
alarms. It can give you more time t o escape before fire spreads. This u nit
can only give an early warning of developing fires if it is installed,
maintained and located where smoke can reach it , and where al l residents
can hear it, as described in this manual. This unit will not sense gas, heat,
or flame. It cannot prevent or extinguish fires .
The alarm shall include a test button that will electronically simulate the
presence of smoke and cause the unit to go in t o alarm. This sequence
tests the units electronics, battery and horn to ensure proper operation.
The unit shall include a piezoelectric horn that is rated at 85 decibels at 10
feet. In a smoke incident, the horn will sound in the repetitive
manner—three beep s , a pause, three beep s , a pause.
The unit shall also include a low battery warning utilizing a brief alarm chirp
every30 -4 0 seconds for a minimum of seven days .
