IS Thermal ROR Detector
5451EIS for Hazardous Areas
Description
The Intrinsically Safe Thermal ROR Detector 5451EIS
uses the rate-of-rise heat detection principle and was
developed for the fi re detection in hazardous areas.
The detector, which is a combined maximum/rate-of-
rise heat detector, is assigned to class A1R and can be
used up to a maximum room height of 7.5m.
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 a detector test device. The detector
can be attached to various bases and it can be protec-
ted against theft.
