Security Brands 37-LKR1 Ascent Link Keypad / Reader

Wireless Mesh Keypad and Proximity Reader for Ascent Systems

The Security Brands 37-LKR1 Ascent Link Keypad + Reader is a wireless mesh access control accessory for compatible Ascent cellular systems. It combines a keypad and proximity card reader in one pedestal-mount unit, allowing an Ascent-controlled gate, door, or other entry point to support both PIN-code access and credential-based access.

The 37-LKR1 communicates through the Ascent Link 900 MHz wireless mesh network and is designed to work up to 1,000 feet from a compatible Ascent Link or primary Ascent unit under typical conditions. Once paired, the unit becomes part of the Ascent access control network and can be managed through Summit Control for cloud-based user and credential management.

This model includes one relay and three digital inputs. The relay can be wired to a gate operator, door opener, magnetic lock, or electric strike, while the digital inputs allow accessory devices to be connected as part of the larger access control installation. The keypad provides visual feedback through smart LEDs, and the network status LED helps confirm whether the unit is connected to the primary controller.

The 37-LKR1 requires an Ascent primary controller to operate. For longer wireless runs, Security Brands offers the Ascent Link Extend 37-LE1 and Ascent Link starter kits to expand the mesh network.
