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.
