Description

Modern commercial environments demand entrance automation that actively adapts to real-world door configurations — not the other way around. The 1L-AC-101SBD steps in as the smart, flexible solution that facility managers, electrical contractors, and procurement teams across India actively rely on when a single sensor must handle both single and double door setups without compromise.

What immediately makes the 1L-AC-101SBD different is its dual-configuration detection engine. Rather than locking facilities into purchasing separate sensor models for different entry widths, this device actively switches between single and double door detection modes — giving project teams the freedom to deploy one trusted model across multiple entry points on the same site. Consequently, inventory management simplifies, installation time drops, and procurement costs actively decrease across every multi-entry project it covers.

Installation, additionally, demands no specialist skills. Teams mount it above the door frame, connect it to standard terminals, and the system actively goes live within minutes. Therefore, projects hit their go-live dates without technical delays holding them back.
