LCN 4040SE-DE 24V RH 689 MC Sentronic AL Holder/Closer

LCN 4040SE-DE 24V RH 689 MC Sentronic Holder/Closer AL offers a robust solution for managing fire and smoke barrier doors. This Grade 1 surface door closer features a slide track arm and double egress design, ensuring reliable operation with a 95-degree hold open capability. The heavy-duty, non-handed closer is engineered for interior doors up to 4'0" and functions seamlessly as a full rack and pinion closer when the hold-open feature is disengaged. Equipped with a 24V power supply, the Sentronic model keeps doors held open until current interruption occurs, at which point it releases the holding mechanism for safe closure. The adjustable hold-open force allows for customizable functionality, while the momentary on/off switch board assembly facilitates easy testing of door release and provides over-voltage protection. Installation is straightforward, with the closer mounting on either the push or pull side of the door. The durable metal cover in a matte silver finish enhances aesthetics and durability, while options for custom powder-coated or plated finishes are available. This commercial-grade closer meets ADA compliance standards and interfaces with alarm systems, making it a versatile choice for various building applications. With a two-year limited warranty, the LCN 4040SE is designed to deliver long-lasting performance and reliability.
