Inspection,Testing and Maintenance. 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 LEDs for indication of status. In a normal standby condition
the LEDs flash Green every 3 seconds. When the detector senses that its
sensitivity has drifted outside the UL listed sensitivity window the
LEDs will flash Red every 3 seconds. When the detector senses smoke and
goes into alarm the status LEDs 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 SPECIFICATIONS Light Source: GaAlAs Infrared LED
