DoorKing 8040-080 Multi-Purpose Receiver, Form Relay, 12-24V AC orV DC, Can be used with MicroClik or MicroPlus Transmitters

Optimize access control and perimeter security with the DoorKing Systems Model 8040 multi-purpose RF receiver. Built for installers and security integrators, this versatile receiver provides flexible integration options—output received transmitter codes as 26, 30 or 31-bit Wiegand to interface with most access controllers, or use the built-in Form C (NO/NC/C) dry contact relay for standalone gate, door or barrier control. The 8040-080 operates at 318 MHz and pairs with MicroPlus or MicroClik transmitters; the 8040-081 runs at 418 MHz for MicroClik-only deployments. With 12–24V AC/DC power capability and a low-power operating mode, the unit is ideal for solar-powered or remote sites where energy efficiency matters. Installer-friendly features include a Master transmitter for quick Learn Mode programming and broad compatibility with DoorKing MicroClik and MicroPlus transmitters. Whether you’re upgrading an access control panel, extending surveillance-triggered entry, or deploying secure monitoring at remote gates, the DoorKing 8040 RF receiver delivers reliable, industry-grade performance.
