The Siemens FP-11 is an intelligent, addressable multi-criteria fire detector. Specifically, it combines a photoelectric smoke chamber, a 135°F thermal sensor, and Siemens’ FirePrint neural-network algorithm. As a result, it distinguishes real fire conditions from deceptive phenomena such as cigarette smoke or steam.
The detector reports continuously to the panel over a supervised two-wire connection. In addition, the FirePrint algorithm is tuned for the specific hazard profile selected at the FACP.
How the Siemens FP-11 Detects Fire
First, an infrared LED illuminates a controlled-pattern smoke chamber. Then, when smoke enters, particles scatter light onto the photodiode. At the same time, an on-board thermistor monitors temperature changes.
Next, the on-board microprocessor runs both inputs through the FirePrint algorithm. As a result, the panel learns whether the signature matches a real fire or a benign source. Furthermore, system logic activates on any of three inputs — smoke, heat, or the neural network decision — for layered protection.
Hazard Profiles — Programmed at the FACP
The FP-11 can be programmed at the FireFinder XLS or MXL panel to one of several application profiles. Specifically:
- Office / Retail
- Lobby
- Computer room
- Dormitory
- Healthcare facility
- Parking garage
- Utility / transformer room
- Hostile environment
- Precious storage
- Air duct
- Warehouse / light manufacturing
If the profile is left unprogrammed, the FP-11 reverts to a default photoelectric/photothermal mode. Therefore, the detector still works on power-up before commissioning is complete.
