Applications
The 710/713CS/LS and 7109/7139CS/LS photoelectric single/multiple
station smoke alarms are designed to give reliable early warning of the
presence of smoke where both audible and visual alarms are required.
The series features a 90dBA solid state piezo signal and a 177 Candela
strobe with “FIRE” lettering. The strobe is listed per UL 1971.
The smoke alarm operates on the light scattering principle, a superior
method of detection in smoldering fires, utilizing a pulsing LED light
source and a photodiode sensor in a fully screened sensing chamber.
Every 4 to 5 seconds the pulsing LED emits an infrared beam that by
passes the photodiode under normal conditions. However, when smoke
enters the sensing chamber, the infrared beam is deflected onto the
sensor by the smoke particles. The LED pulse rate increases to 8 times
the normal rate, and after the photodiode confirms that smoke is present
for 2 consecutive pulses, it will produce the signal necessary to trip an
alarm.
Upon activation, the alarm will emit a 90dBA local audible signal and
activate the high intensity strobe. During the alarm period the strobe will
flash at a brightness of 177 candela 60 times per minute. After the smoke
has cleared from the detector, the unit will revert to the normal stand-by
condition.
