Siemens FDOOT221 multi-sensor smoke detector

Technical Specification

Features:
  • Make: Siemens
  • Model code: FDOOT221
  • Type: Smoke
Additional info:

Siemens FDOOT221 is a multi-sensor smoke detector works according to the scattered-light principle with two sensors, optical forward and backward scattering. Opto-electronic sampling chamber blocks disturbing extraneous light but optimally detects both dark and light smoke particles. Two additional heat sensors increase the fire detector’s immunity to deceptive phenomena. Signal processing with detection algorithms (DA).
