The LCN 8310-878 is the OEM Single Door Safety Package from the LCN 8310 Series, the Monitored Safety Sensor Kit for single door automatic door operator applications. The package contains two door-mounted sensors, one control hub, all wire harnesses, and all mounting hardware. Per the official LCN product catalog: "Contains two door-mounted sensors and a control hub that perform the swing door safety functions and provides the sensor monitoring required by A156.10. All wire harnesses and mounting hardware included." The 8310-878 is specifically engineered for use with LCN Senior Swing automatic door operators. Available (3-4 weeks).

What the LCN 8310-878 Single Door Safety Package Provides

ANSI A156.10 (Power Operated Pedestrian Doors) defines two related but distinct requirements for automatic swing door safety systems. The first is detection and response: when a person or object enters the swing path of the door, the door must detect the obstruction and stop or reverse before contact. The second is monitoring: the sensor system must actively track its own operational status and report faults or failures to the door operator control system. Many sensor configurations address detection without addressing monitoring. The 8310-878 addresses both.

The two door-mounted sensors in the 8310-878 cover the door swing path, detecting obstructions as the door moves. The control hub receives sensor signals, interprets them, and commands the Senior Swing operator to stop or reverse as needed. It also actively monitors all sensor inputs for faults. If a sensor fails or loses communication, the hub detects the condition and the system reports accordingly. This monitoring function is what makes the 8310-878 a "monitored" safety kit versus a standard sensor-only installation, and it is what satisfies the ANSI A156.10 monitoring requirement.

LCN 8310-878 vs Individual Sensor Components: Why the Kit Matters

The LCN 8310 Series catalog includes individual sensor components that can be purchased separately. The 8310-804-1 is a single door-mounted active sensor for leading edge detection. The 8310-804-2 provides two active sensor modules for full face detection. The 8310-877 is a header-mounted safety sensor using Diffused Infrared Technology with nine selectable detection patterns, requiring the 8310-859 handheld remote for distance programming.

Purchasing and installing these individual sensors does not produce the same result as the 8310-878 kit. The individual sensors provide detection capability but do not include the ANSI A156.10 monitored control hub. Without the control hub, there is no system-level monitoring output and no ANSI A156.10 monitoring compliance. The 8310-878 provides detection, response, and monitored compliance in a single specified package, which is why the LCN catalog lists it as a complete "Safety Sensor Kit" rather than as individual sensor components.

LCN 8310 Actuator Catalog: Single Door vs Double Door Safety Packages

The 8310 Series safety package catalog offers two configurations based on the number of door leaves in the installation:

8310-878 (this product) = Single Door Safety Package. Two door-mounted sensors and one control hub. For single door leaf automatic swing door applications. Provides ANSI A156.10 monitored safety compliance for one door.

8310-879 = Double Door Safety Package. Four door-mounted sensors and one control hub. For door pairs where both leaves are powered by automatic operators. Provides ANSI A156.10 monitored safety compliance for both leaves from a single hub.

The critical distinction between ordering one 8310-878 per door leaf on a double door pair versus ordering one 8310-879 is the hub integration. The 8310-879 provides unified monitoring across both door leaves from one control hub, with one monitoring output for the access control or building management system. Two separate 8310-878 installations on a double door pair produce two separate monitoring outputs, which may not satisfy specifications requiring integrated pair monitoring.

For single door Senior Swing installations, the 8310-878 is the correct single-order solution. Finish is not applicable - this is a functional sensor and electronics package.
