Functions:<ul>
Photoelectric technology is generally more steady than ionization technology at detecting large particles, which tend to be produced in greater quantity by smoldering fire, which may smolder for hours before bursting into flame
Sources of these fires may include cigarettes
The unit monitors the air and when smoke reaches its sensing chamber, it alarms
It can give you more time to escape before fire spreads
This unit can only give an early warning of developing fires if it is installed, maintained and located where smoke can reach it and where all residents can hear it
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 into alarm
This sequence tests the units electronics, battery and horn to ensure proper operating
The unit shall include a piezoelectric horn that is rated at 85 decibels at 10ft
In a smoke incident, the horn will sound in the repetitive manner, three beeps, a pause, three beeps, a pause
The unit shall also include a low-battery warning utilizing a brief alarm chirp every 30 to 40 seconds for a minimum of seven days
The alarm will utilize a red LED that shall flash once every 30 to 40 seconds to indicate the alarm is receiving power</ul>
