DESCRIPTION
The FDK series photoelectric smoke detectors detect
combustion products ( smoke) generated by a fire, and
transmit an alarm signal to the fire alarm control panel.
The photoelectric smoke detector can detect a fire in an
earlier stage than a heat detector. Generally, this detector
is installed in the spaces such as basements, ordinary
floors, corridors, staircases, elevator shafts.
OPERATING PRINCIPLE AND FUNCTION
The photoelectric smoke detector is composed of a light
source, light sensing element, light shielding element and
detecting chamber. The light source ( a light-emitting
diode) emits light at intervals of about 3.5 seconds, which
does not reach the light sensing element ( photo diode)
under normal conditions because of the light shielding
mold. If smoke enters the detecting chamber, the light
from the light source is scattered by smoke particles and
reaches the light sensing element. The light reaching the
light sensing element varies with smoke density and if it
exceeds the predetermined level, the detector operates
and automatically holds its operation.
The detector then transmits the alarm signal to the fire
alarm panel and the response lamp of the detector turns
on. | | |
