LCN 8310 Series is a modular system of touchless and push-plate door actuators, wireless transmitter/receiver sets, mounting boxes, escutcheons, weather/trim rings, safety sensors, and accessory kits used to remotely actuate LCN automatic swing-door operators (e.g., 4630/4640, 7900 pneumatic auto-equalizer, 9100 Benchmark, Senior Swing 2800/9500, Mid Swing 2900/9700 series). Touchless actuators and hardwired push plates require a wired, low-voltage power/control connection back to the door operator control box; most are also compatible with a 433 MHz or 900 MHz wireless transmitter/receiver pair for wireless actuation signaling instead of a run of activation wire. A subset of push plates (8310-852WP/853WP) are fully wireless/battery powered with no field control wiring at the plate itself (only the receiver, sold separately, is wired to the operator).
| Touchless actuator supply (8310-813) | 12-24 VAC ±10% or 12-24 VDC +30%/-10%, SELV-compatible power supplies only; power consumption < 1.5W; output is a voltage-free relay (max 60VDC/125VAC, 1A resistive, 30W) |
|---|---|
| 900 MHz receiver input voltage (8310-880) | 12-24 VAC/VDC; relay contact rating 1.0A@30VDC, 0.3A@60VDC, 0.5A@125VAC |
| Wireless transmitter power consumption (900 MHz) | 30mA (standard TX) / 40mA (RX) / 22mA (retrofit TX) |
| Receiver capacity | up to 74-75 transmitters per standard receiver; unlimited for 'universal' mode |
| Low-voltage wiring | Required |
| Basis | Structured, independently qualified product connection evidence |
| Preparation | Prepare the sensor mounting position on the header/frame and align the harness route. Use the supplied mounting screws; where wiring passes directly through the header, the manual specifies a1/2-inch passage beside the left end cap. Fit the HMSS spacer when the reveal is under3inches or door-mounted safety sensors are also used. Confirm the actual reveal and sensor arrangement before drilling. |
| Electrical | Low-voltage wiring is required. The8310-877 manufacturer specification calls for12-24VAC/VDC (+/-10%). For the illustrated compatible SeniorSwing controller, use the supplied sensor harness: white10-position plug at the sensor, black6-position plug at controllerP1; do not use the crossed-out7-terminal connector. That supplied harness has six conductors in one supplied cable assembly. Its length is shown in the manufacturer specifications. This is one supplied harness per sensor, not a count of additional cable pulls or all system wiring. For other operators, follow the matching controller diagram before cutting off the controller plug. Gauge and shielding are not specified in this manual. Monitoring must follow the selected interface instructions; connector position count is not a conductor count. |
| Preparation required | Yes |
| Electrical wiring required | Yes |
