We Supply Sentronic LCN Door Closers
We provide a space to read up on some of the Sentronic LCN products below. Please visit our product pages to gather further information about these items.
LCN 4040SE Sentronic Door Closer
The Sentronic LCN 4040SE allows the option to choose an LCN 4040SE 24 volt Sentronic door closer or an LCN Sentronic 4040SE 120 volt closer. Choose either the LCN 4040SE 24 volt Sentronic door closer or the 120 volt from our Voltage dropdown menu on our LCN 4040SE Sentronic Door Closer product page.
Whether you choose the 120 volt or the LCN 4040SE 24 volt Sentronic door closer, both of these options meet the regulations of the NFPA 101 Life Safety Code and ANSI/BHMA. In either voltage, the LCN 4040SE Sentronic Door Closer is UL listed as appropriate for fire labeled and smoke barrier doors.
The LCN 4040SE Sentronic Door Closer is non-handed and can be surface mounted on either the pull side or push side of a door. It can be used to replace the older versions such as the Sentronic LCN 4110SE and the Sentronic LCN 4010SE.
Sentronic LCN 4310HSA And 4410HSA
The Sentronic LCN 4310HSA and the Sentronic LCN 4410HSA both comply with the NFPA 101 Life Safety Code and ANSI/BHMA regulations. They were made with the purpose of being installed in facilities with high volumes of traffic.
These electronic closers both have a Sentronic LCN HSA Scanner that will pick up on individuals walking through the doorway. The LCN Sentronic hold open mechanism will come into play every time the door is open 80 degrees and will keep the door open until everyone passes through.
These can be applied to either right-handed or left-handed doors. The Sentronic LCN 4310HSA should be surface mounted to the pull side of the door with a single lever arm. The Sentronic LCN 4410HSA should be surface mounted on the door’s push side with a regular arm.
LCN Sentronic Door Closer 4310ME And 4410ME
The LCN Sentronic Door Closer 4310ME and the Sentronic LCN Door Closer 4410ME are UL listed as appropriate for use on both smoke barrier and fire labeled doors. These LCN Sentronic closers both comply with ANSI/BHMA regulation codes. Plus, they adhere to the set of standards for the NFPA 101 Life Safety Code.
Both the 4310ME and 4410ME LCN Sentronic closers have an on and off switch to control the LCN Sentronic hold open function. They are built from cast iron and can be used on either left-handed or right-handed doors.
The main difference between the two products is their mounting style. The LCN Sentronic Door Closer 4310ME should be surface mounted to the pull side of the door with a swing-free arm. The Sentronic LCN 4410ME should also be surface mounted to the door but on the push side with a regular arm.

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.

The 4412HSA SENTRONIC® is an electrically controlled closer/holder designed to provide easy passage for groups of pedestrians through high traffic doors.

After the last pedestrian in a group passes through the doorway, the system timer releases the hold-open, closing the door under control of the heavy duty closer.
