    Planning Risk of fire In production facilities where highly combustible materials such as flammable liquids, cotton, paper etc. are processed and where electrical machines are operated, the fire risk is very high. Minor overheating or sparks may cause a fire. In a storehouse where steel is stored and where no electrical installation is provided with the exception of lighting, the fire risk is very low.

  • Page 53: Technical Ambient Supervision Alarm

    Ambient features In markets where the use of the 'Technical Ambient Supervision Alarm' is permitted, the neural fire detector FDOOTC241 can be positioned above or near objects which require the ambient temperature or CO concentration to be monitored to prevent damage.

  • Page 54: Temperature Monitoring

    2 Output signal When an ambient temperature of 35 °C is reached, the neural fire detector FDOOTC241 sends an output signal to the control panel. As long as the hysteresis range is not undershot, the output signal is sent. In the example shown, the output signal is no longer sent once the ambient temperature of 30 °C (threshold value minus hysteresis range) is undershot.

  • Page 55: Co Monitoring

    Planning 4.3.1.2 CO monitoring CO monitoring compares the current measured CO concentration with a preset threshold value. Alarming takes place when the current measured CO concentration temperature exceeds the set threshold value. You can set the CO concentration threshold value in stages of 5 ppm between 20 and 600 ppm.
