LCN Sentronic Closer 4040SE
The LCN 4040SE Sentronic Door Closer is a heavy duty, non-handed, non-sized closer/holder designed to provide single point hold-open for fire and smoke barrier doors. The door is held open until current interruption releases the holding mechanism and the door closes. Single lever (track) arm closer is specifically designed for interior doors. Choice of finishes, track functions, and installation accessories meet virtually all life safety requirements. The SE stands for Single Point Electronic, with this closer the hold open point can only be one point, so the closer has to be positioned on the door to get the proper hold open point.
This technology has been around since 1972, but back then you would order the 4110SE or 4010SE. These were application specific closers, so you had to specify the hand of the door, door size, and the type of mounting. If you do have an older version, the 4040SE will replace it.
