Thermal Detector

5251EM

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.

System Sensor/200 protocol

• For use as maximum heat or

rate-of-rise heat detector

• Alarm temperature 58°C or 78°C

software selectable
