Schlage Scan Ii-b Passive Infrared Motion Sensor

Product Description

The SCHLAGE SCAN II-B is a passive infrared motion sensor designed for access control and door activation applications. It detects occupant movement through infrared energy changes within its detection zone and signals a connected door or access control system to respond. Operating on 12/24 VAC/VDC, the unit suits a wide range of panel and power supply configurations found in commercial installations. The ABS plastic enclosure in black provides durability in typical interior environments. An externally visible activation LED gives installers and technicians immediate visual confirmation that the sensor has triggered, simplifying commissioning and troubleshooting.

The SCAN II-B is used in commercial and light industrial facilities where automatic door activation or access control integration is required. Typical applications include hands-free door actuation in corridors, vestibules, and secure entry points. The field-selectable fail safe and fail secure modes allow the installer to configure the relay output behavior to match the door hardware and site security requirements without replacing the unit. This makes it appropriate for both egress-side automatic door openers and access-controlled entry points.

Key Features

• Passive infrared detection for reliable, contactless motion sensing
• Field-selectable fail safe or fail secure relay output mode
• Operates on 12/24 VAC/VDC for broad power supply compatibility
• Externally visible activation LED for fast visual confirmation during install and service
• ABS plastic enclosure in black for durability in interior commercial environments

Compatibility

Designed as an OEM-style replacement or new-installation passive infrared motion sensor for commercial access control and automatic door activation systems requiring a 12/24 VAC/VDC input and selectable fail safe or fail secure relay output.

Installation Notes

Installation is typically performed by a licensed low-voltage or access control technician familiar with door hardware and relay wiring. Power down the access control panel or door operator before wiring the sensor. Verify the fail safe or fail secure field selection matches the door hardware configuration before energizing the system. Follow applicable local codes and manufacturer wiring guidelines for low-voltage control circuits.
