The Intrinsically Safe Optical Smoke Detector SLR-E-IS
uses the scattered light principle and was developed
for the detection of smoke particles in explosion-prone
rooms.
The modern design of the sensing chamber al-
lows to reliably evaluate the characteristics of fi re.
Conventional technology is used for alarm transmission
to the fi re detection control panel. In conjunction with the
Safety Barrier ES58-2, the detector reaches the given
Ex classifi cation. The two LEDs with 360° visibility indi-
cate the activated condition of the detector. By means
of an auxiliary module, the connection to an ADM loop
is possible.
A detector function test can be conducted by using test
gas. The detector is attached to the IS Detector Base
YBN-R/4IS.
