- Hermetic reed detector for recessed mounting
- Small housing with round flange
- Housing diameter 12.7 mm
- Operating temperature range from -10 °C to +55 °C
- Distance of closing reed switch contacts 19 mm and opening 24 mm
Intended use and application of the B-2FL BR detector
The B-2FL BR magnetic detector is used to detect the opening of doors, windows and other movable elements as an element of burglary and assault signaling systems. Thanks to recessed mounting, the detector is invisible from the outside after installation, which contributes to the aesthetics of the finish and makes it difficult for unauthorized persons to locate it.
The B-2FL BR model is a brown-colored version, designed especially for dark-colored woodwork, while the corresponding B-2FL model comes in white. The detector is used in wired systems as a perimeter protection element in residential, office and industrial buildings.
Design and mechanical properties
The B-2FL BR is a small hermetic reed detector with a round flange, designed for recessed mounting in the ground. The diameter of the housing is 12.7 mm, and the dimensions of the reed switch housing and magnet housing are 25.4 x 15.5 mm. The hermetic design and high permissible operating humidity of up to 93±3% allow the detector to be used in demanding environmental conditions.
The cable length is 450 mm, which makes it easy to bring the wiring to the installation boxes or input modules of the alarm system. The detector meets the requirements of environmental class II according to EN 50130-5.
Electrical and operating parameters
The B-2FL BR detector is an NC (normally closed) type detector, designed for use with control panels and alarm modules supporting this type of input. The closing distance of the reed contacts is 19 mm, while the distance of their opening is 24 mm, which allows for proper selection of the gap between the reed element and the magnet.
The maximum switchable voltage of the detector is 100 V, the maximum load power is 10 W, the maximum switchable current is 500 µA, and the maximum contact resistance is 200 Ω. The operating temperature range is from -10 °C to +55 °C, which allows expLoatation in typical indoor and partially outdoor conditions, according to the environmental class of the device.
