APPLICATION

The HOCHIKI America SLR-835B Series can be used in

all areas where Photoelectric Smoke Detectors are required.

It is suited for smoldering or flaming fires.

 

OPERATION

The SLR-835B Series photoelectric smoke detector

utilizes two bicolored LED's for indication of status. In

a normal standby condition the LED's flash Green every

3 seconds. When the detector senses that its sensitivity

has drifted outside the UL listed sensitivity window the

LED's will flash Red every 3 seconds. When the detector

senses smoke and goes into alarm the status LED's

will latch on Red.

The unit is comprised of an LED light source and silicon

photo diode receiving element. In a normal standby

condition, the receiving element receives no light from

pulsing light source. In the event of fire, smoke enters

the detector and light is reflected from the smoke

particles to the receiving element. The light received is

converted to an electronic signal. Signals are processed

in the comparator, and when two consecutive signals

 exceeding the basic level are received within a specific

period of time, the time delay circuit triggers the SCR

switch to activate the alarm signal. The status LED

lights continuously during alarm period.
