Honeywell IQ8Quad 802371 Smoke Detector

Honeywell 802371 IQ8Quad Addressable Optical Smoke Detector

Honeywell 802371 IQ8Quad is an addressable professional smoke detector that provides early fire detection using advanced optical sensing technology. It delivers high performance and system reliability, particularly in projects with Esser fire panel infrastructure.

The IQ8Quad series works seamlessly with FlexES Control fire panels, IQ8Control and IQ8Compact panels, delivering maximum efficiency in fire alarm systems.

Optical Smoke Detection Technology

The 802371 model operates using the light-scattering principle and offers high sensitivity to slow-developing and smouldering fires. Its intelligent algorithm reduces false alarms, making it suitable for use in industrial facilities and commercial buildings.

Addressable Esser Technology

• Each detector can be monitored individually via the panel

• The exact location of a fire is displayed

• Provides high stability in Esser fire alarm panel systems

• Enables easy commissioning and maintenance on large projects

Line Safety with Integrated Isolator

The built-in short-circuit isolator allows the system to continue operating if a fault occurs on the loop. This feature is particularly important in large facilities using FlexES Control fire panels.
