Siemens FDO181 Smoke Detector FDO183 Photoelectric Smoke Fire Detector

I.  General description: 

FDO181 point-type photoelectric smoke fire detector utilizes an optical sensor, employing the principle of light scattering to enhance the detection capability for smoke particles generated by fires, thereby significantly improving the sensitivity to both open and concealed fires, allowing for early detection of fire incidents.

- Equipped with an internal CPU, the received signals are processed by intelligent algorithms for fire identification.

- The detector's sensitivity can be selected through parameter settings, allowing for adjustments according to the monitored environmental conditions.

- Adopting a new smoke labyrinth structure effectively prevents external light interference, ensuring accurate detection of fire smoke.

- Fully automatic address setting, eliminating the need for encoder settings or dip switches.

- Particularly suitable for early detection and alarm of concealed fires or flames that produce smoke.

- Strong resistance to environmental factor interference, including dust, fibers, insects, humidity, extreme temperatures, electromagnetic interference, corrosive gases, vibration, and non-fire smoke.

- The alarm light is visible in all directions, 360°.

- Communicates with the controller via the FD18-BUS loop with non-polarized connections.

- Employs a single photo-sensitive component scattering light principle.

- Features automatic compensation to reduce the impact of dust on detection sensitivity; when the detector is heavily contaminated and cannot be compensated, it will report a fault to the controller.

- Comes with a dust cover to prevent on-site decoration pollution.

III. Performance testing suggestions for the FDO181 point-type photoelectric smoke fire detector:

1. Conduct an annual visual inspection of all detectors and replace those heavily contaminated or mechanically damaged.

2. Detectors kept on long-term standby should be stored in sealed packaging.

3. Regularly perform smoke tests periodically, once a year.
