5. Functional Description
5.1 General
The AutroGuard® Multicriteria Protector features two heat sensors
and a smoke detection chamber. The type of operation can be
configured to fit the application, Heat, Optical or Multisensor.
The following chapters describe the functionality and configuration
possibilities of the main functions of the protector.
5.2 Chamber Design
The chamber design is shown below, including:
• Smoke detection receiver
• Smoke detection transmitter (two forward-scattering LEDs)
• Smoke detecton transmitter (one IR backward-scattering LED)
The chamber allows very fast smoke intrusion, meaning that the
smoke concentration inside the chamber is as close as possible to the
smoke concentration on the outside. This leads to very fast detection
of smouldering fires.
