Siemens FDOOT241-9 multi-sensor smoke detector

• Make: Siemens
• Model code: FDOOT241-9
• Type: Smoke

Siemens FDOOT241-9 is a multi-sensor smoke detector that 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.
