LCN 4040SEH-3034SEH - 4040SEH Series Hold Open Track Roller and Slider

Not usually the first thing to check. The 4040SE holds the door until current interruption releases the holding mechanism, and the closer carries a momentary on/off switch board assembly for testing door release that also gives over-voltage protection. That board is field replaceable, so test release with it first. If the door releases electrically but drags or hangs in the track, that points to the roller and slider.

No. The 4040SEH-3034SEH roller and slider are internal track components for the LCN 4040SE series electrified fire and life safety closer/holder, where the door is held open until a current interruption releases the holding mechanism. The Deltana DCHA1050 is a hold open arm built for the Deltana DC10 closer, so it is a mechanical arm for a different closer series rather than a replacement part that rides in an SE track. If you have an SE track holder, stay with the SE series roller and slider; the DCHA1050 applies to a DC10 installation.

No. The 4040SE series closer/holder is non-handed and mounts on either a right or left hand door, and it can go on the push or pull side. The track hardware follows the closer, so there is no left or right version to specify.

The electrical difference between the SE tracks is in the holding solenoid circuit, 24V or 120V, which is specified when the closer is ordered. The roller and slider are the mechanical parts riding in the track, so voltage is not a selection point for them. What does matter is that you are working with an SE style track on a 4040SE closer rather than a plain non-hold-open track arm.

The 4040SEH series hold open track hardware is listed ADA compliant and is a commercial grade product, not residential. The closer itself functions as a full rack and pinion closer whenever hold-open is not engaged or current has been interrupted, so opening force behavior is that of the standard 4040 closer.

The 4040SE track is an electrified hold-open: it drops the door on current interruption, which is what a fire or smoke barrier door needs. If the opening does not need alarm release and you just want the door to stay put mechanically, a hold open arm such as the Deltana DCHA1050 for the DC10 closer is the simpler route. For a controlled closing cushion rather than hold-open, the Deltana DCCA4041 cushion arm for the DC40 closer is the other direction.

Either works. The 4040SE accepts concealed or surface wiring, which lets you retrofit an existing opening without cutting the frame when concealed raceway is not available. It also interfaces with alarm systems, though LCN asks that you consult the factory for the full integration detail.

The 4040SEH-3034SEH is a hold open track roller and slider for the LCN 4040SE series closer/holder, a surface closer that mounts on either the push or pull side and functions as a full rack and pinion closer when hold-open is not engaged. The Deltana DCCA4041 is a cushion arm for the Deltana DC40 closer, which is an arm assembly for backcheck and stop duty rather than a track component. They serve different closers and are not interchangeable.

The LCN 4040SE hold open track, which the 4040SEH-3034SEH roller and slider serve, is built for single point hold-open on fire and smoke barrier doors and is ADA compliant for commercial use. On a pivoted opening with no hold-open release requirement, a Dorma 15323 1-1/2 inch offset bottom arm with cover is a standard duty pivot arm carrying no fire rating, and the Norton Rixson 40 Series heavy duty center hung floor closer with cement case handles doors to 300 lb. Those address door swing control rather than electrified hold-open.
