IS Ionisation Smoke Detector
1151EIS for Hazardous Areas
Description
Specifi cations
The Intrinsically Safe Ionisation Smoke Detector
1151EIS was developed for the safe detection of a
wide range of smoke aerosols. The modern design of
the ionisation chamber allows 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
indicate the activated condition of the detector.
A detector function test can be conveniently conducted
using a magnet or test gas. The detector can be at-
tached to various bases and it can be protected against
theft.
