Automatic heat detector with fast semiconductor sensor for reliable detection of fires with rapid temperature rise and integrated maximum value function for the recognition of fires with slow temperature rises. Fire detector with decentralized intelligence, automatic function self-test, alarm and operations data storage and alarm display.

A remote indicator can also be connected.

Features & Benefits:

System benefits:

Optimally matched to the ES Line system

With multisensor detectors for the detection of all fires, even under the most difficult operating conditions

Up to 30 detectors per detection group

Reliable detection:

Uniform response sensitivity of the detector for all different types of fire for the multisensor detectors

Large distance between signal and interference magnitudes due to special sensor and electronics design for suppressing electromagnetic influences

Automatic adaptation to varying environmental influences

Electronic compensation also called drift-compensation of long-term influences of contamination or aging

Reliable false alarm suppression:

High reliability against false alarms by temporal evaluation of different sensor criteria, with built-in insect screen and sealed against rear air flow entry

Exclusion of signal forms not typical of fires through special filter algorithms

Automatic self-monitoring of the detector electronics

Automatic self-monitoring of sensors for function and condition

Maintenance:

Designation of the heat detector by a black ring on the light pipe

Hours of operation, alarm and fault counter in each detector

Operation data retrieval of all detectors of a group with standard service PC and field bus interface

Detector LED for alarm display and as an identification display in the service (for maintenance with 8000 tools)

Wide range of accessories:

Standard socket and relay base

Socket adapter for ceiling installation

Dust caps optional for fire detectors and detector base

Kit for suspended mounting

Certifications:

EN 54-5 A1R
