The A100 Series are keyless entry controls for deadlocks, deadlatches and exit devices, that are compatible with aluminum stile, steel and wood door applications. An authorized card presentation is confirmed with an audible beep and visual change in the red/green LED indicator – displaying the locked/unlocked status. A high-speed motor engages an internal clutch to enable the exterior lever handle operation. Upon timeout, the lever operation is disabled until the next authorized card presentation or by key override.
