Description
The addressable Thermal Detector 5251EM is based
on the heat principle and was developed for the indoor
temperature supervision in a wide range of fi re detec-
tion applications.
When used with a Fire Detection Control Panel Series
BC216, the detector can operate either as maximum
heat detector with alarm temperature 58°C (EN 54-5
Class A1S) or alarm temperature 78°C (EN 54-5 Class
BS), or as rate-of-rise heat detector with a maximum
temperature of 58°C (EN 54-5 Class A1R).
The proven ADM loop technology with System Sen-
sor/200 protocol establishes a permanent communi-
cation between the fi re detection control panel and the
detector. That ensures a periodical function testing of
the detector. Fires are safely detected in the control
panel by continuously analysing the measured values.
The two LEDs with 360° visibility indicate the activated
condition of the detector. The detector address is se-
lected with two decadic rotary switches, thus allowing
to change the detector without additional tools.
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.
