Security Brands 37-LK1 Ascent Link Keypad

Wireless Mesh Keypad for Ascent Access Control Systems

The Security Brands 37-LK1 Ascent Link Keypad is a wireless mesh keypad accessory for Ascent cellular access control systems. It provides a keypad wherever one is needed within an Ascent Link network, allowing gates, doors, and other controlled entry points to be added without running long control wiring back to the primary Ascent unit.

The 37-LK1 connects wirelessly to a compatible Ascent cellular primary controller through the Ascent Link 900 MHz mesh network. When paired with the primary unit, it can be managed through Summit Control for cloud-based access control, including access credentials and system management tied to the Ascent platform.

This keypad includes one relay, one 26-bit Wiegand input, and three digital inputs. The relay can be wired to a gate operator, door opener, magnetic lock, or electric strike, while the Wiegand input allows connection to a compatible Wiegand device such as a card reader or keypad. Smart status LEDs provide visual feedback for power, relay activity, and wireless network connection.

The 37-LK1 is designed to work up to 1,000 feet under typical Ascent Link range conditions. For longer wireless runs, Security Brands offers the Ascent Link Extend 37-LE1 and starter kits that expand the wireless mesh network.
