The LCN 8310-879 is the OEM Double Door Safety Package from the LCN 8310 Series, the Monitored Safety Sensor Kit for all double door automatic door operator applications. The package contains four door-mounted safety sensors, one control hub, all wire harnesses, and all mounting hardware. It provides the swing door safety monitoring functions required by ANSI A156.10 (Power Operated Pedestrian Doors), and is specifically designed for use with LCN Senior Swing automatic door operators as well as other LCN 8310 Series door system configurations.

The package is complete as shipped. No additional sensor, hub, or wiring components are required for a double door installation beyond the 8310-879 kit and the door operator itself.

What the LCN 8310-879 Double Door Safety Package Does

Automatic swing doors must detect and respond to obstructions in the door's swing path. ANSI A156.10 defines the detection and response requirements: when a person or object enters the swing path of an automatic door, the door must stop or reverse before contact occurs. The 8310-879 provides the sensor system that performs this detection for both leaves of a double door pair.

Each of the four door-mounted sensors in the 8310-879 is installed on the door leaf itself, monitoring the zone in front of and around the door as it swings open. When a sensor detects an obstruction in the swing arc, it sends a signal to the control hub. The hub evaluates the signal and commands the door operator to stop or reverse movement before the door contacts the obstruction.

"Monitored" is the key descriptor in the official product name. Beyond basic detection and response, the 8310-879 provides active monitoring of the sensor system's operational status. The control hub confirms that all sensors are functional and reporting correctly. This monitoring output connects to the door operator's control panel or building management system, enabling compliance reporting and fault detection without requiring manual sensor testing at the door. This is the ANSI A156.10 monitoring requirement that many healthcare and institutional facility specifications mandate.

LCN 8310 Series: Safety Sensor vs Actuator Family

The LCN 8310 Series covers both touchless actuators (the activation side that triggers door opening) and safety sensors (the protection side that prevents door contact with pedestrians). These are separate product categories within the same 8310 Series catalog and serve different functions in an automatic door system.

The 8310-810 Series = heavy-duty stainless-steel touchless actuators for high-use and abuse environments. The 8310-813 Series = standard medium-duty touchless actuators for conventional commercial applications. The 8310-815 = harsh-environment touchless actuators with IP65-rated enclosures. The 8310-816 Series = close-proximity stainless-steel actuators for specific activation zones.

The 8310-879 is on the safety sensor side: it does not activate the door, it monitors and protects pedestrians after the door is activated.

LCN 8310-879 vs 8310-878: Double Door vs Single Door

The 8310 Series safety package catalog offers two configurations based on door count:

8310-878 = Single Door Safety Package - contains two door-mounted sensors and one control hub for single door leaf installations. Provides the same ANSI A156.10 monitored safety function for one door leaf.

8310-879 (this product) = Double Door Safety Package - contains four door-mounted sensors and one control hub for double door pair installations. Two sensors per door leaf provide coverage of both leaves from one control hub and one ANSI A156.10 monitoring output.

For double door applications, the 8310-879 is the correct single-order solution. Ordering two 8310-878 single door packages and combining them does not produce the same integrated double door monitoring that the 8310-879 provides through its unified control hub.
