General
BG-21 is a 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.
The detector can be used with most conventional fire alarm panels giving alarm on the current increase principle. 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.
Performance class can be configured by the system according to table 1.
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.

Application
The 116-BG-21 has a high IP rating making it suitable for the harshest environments. It may be used with most conventional fire alarm panels. An alarm resistor can be fitted to suit the alarm current required by the detection zone.
The performance class (Class 1 to 3) according to EN54-10 can be configured as required. The advanced signal processing and DYFI+ intelligence ensure that the detector has a high immunity to nuisance alarm sources in combined with fast detection of real fires.
Installer and maintenance friendly
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.
