Our EB80TL is a surface mount illuminated request to exit button from our DX line of access control products. The LED indicator shows white for Power OFF, blue for Power ON (standby) and green for Power ON! When connected to your access control board, this will trigger the release of the electric door strike or mag lock when leaving a building. Lightweight at just 0.12kg and measuring only 96 x 50 x 20 (mm), this works well in many different applications.
