BG-21 is a conventional point flame detector for detection of fires involving combustion of carbonaceous materials.
The detector has a high IP rating making it suitable for the harshest environments. Advanced digital signal processing algorithms ensure fast detection of real fire scenarios combined with high immunity against nuisance alarms.
An alarm resistor must be fitted between terminal 3 and 4. The value of the alarm resistor can be dimensioned for correct alarm current depending on the panel.
The advanced signal processing and DYFI+ intelligence ensure that the detector has a high immunity to any nuisance alarm source combined with fast detection of real fires. This makes the BG-201 detector the obvious choice for demanding applications such as a ship’s engine room.
Principle: Two infrared sensors detect the infrared spectrum from a fire. The sensors evaluate different parts of the infra red spectrum using this information to verify that the signals correspond to the characteristics of a real flame.
