The LCN 8310-3882 is the OEM double door activation and safety sensor package for the LCN Senior Swing automatic door operator. It is a complete, pre-specified kit for simultaneous pair and independent pair double door installations, covering both the pedestrian detection (activation) and the obstruction protection (safety) functions in a single order. The package includes two 8310-875 header mount activation sensors and one 8310-879 monitored safety sensor kit, which contains four door-mounted safety sensors and a control hub.

This is a Senior Swing-specific package. The 8310-879 monitored safety sensor kit is compatible with Senior Swing operators only. Confirm Senior Swing compatibility before ordering.

LCN 8310 Series Actuators: Activation Sensors vs Safety Sensors

The 8310 Series covers two functionally distinct sensor types that work together in any automatic door installation but perform different roles.

Activation sensors (8310-875, header mount) detect pedestrian intent to activate the door. The 8310-875 is a microwave motion sensor operating at 24.125 GHz, mounted in the door header. When a pedestrian approaches the door or waves a hand in front of the sensor, the microwave field detects the motion and sends an activation signal to the Senior Swing control box, triggering the powered opening cycle. No physical contact with the door, push bar, or wall plate is required. The sensor runs on 12/24 VAC/DC and ships with a 6-foot cable. It is ADA compliant and meets Buy American Act (BAA) requirements. The double door package includes two units - one per door leaf.

Safety sensors (in the 8310-879 kit, door mounted) detect obstructions in the door's swing path during operation. If a pedestrian, wheelchair, cart, or other object is present in the path of the swinging door leaf while the operator is driving the door to the open or closed position, the safety sensors trigger a stop or reversal. These are active sensors that continuously monitor the door's swing zone throughout the operating cycle.

LCN Actuator Catalog: What "Monitored" Means on the 8310-879

The monitored designation on the 8310-879 safety sensor kit refers to ANSI A156.10 compliance. ANSI A156.10 is the performance standard for power-operated pedestrian doors, and its safety sensor provisions require not just that safety sensors prevent door contact with pedestrians, but that the system can detect when a safety sensor itself has failed. The control hub in the 8310-879 kit continuously monitors the operational status of all four door-mounted sensors. If any sensor loses power, goes offline, or fails its self-test, the control hub flags the failure. In a monitored system, a failed safety sensor does not result in a door that continues to operate without pedestrian protection - the system detects the fault.

The four sensors in the 8310-879 kit are distributed across both door leaves, providing leading edge coverage on each leaf for the full double door swing zone.

LCN Door Actuator Package: 8310-3882 vs the 8310 Series Package Family

The 8310-3882 sits in a four-package family covering the full Senior Swing operator range:

The 8310-3881 is the single door version - one activation sensor and two safety sensors (8310-878 single door safety kit) for single-leaf applications (9530IQ pull side, 9540IQ push side).

The 8310-3882 is this product - the double door version with two activation sensors and four safety sensors (8310-879 double door safety kit) for 9550IQ simultaneous pair and 9560IQ independent pair installations.

The 8310-3891 is the simultaneous pair healthcare package with a header safety sensor, spacer, four door-mount sensors, and two harnesses. The 8310-3892 is the independent pair healthcare package with two header sensors, two spacers, four door safety sensors, and two harnesses.

The 8310-3882 is the standard commercial specification for double door Senior Swing installations where touchless activation and ANSI A156.10 safety monitoring are both required. The healthcare packages (8310-3891 and 8310-3892) add spacer and harness components for healthcare-specific mounting configurations.
