LenelS2 Installer is a mobile application for seamless provisioning and management of Allegion Schlage No-Tour offline deadbolts. The No-Tour feature eliminates the need for staff to visit a lock when replacing a credential. Instead, when a cardholder presents a smart credential to the lock, the lock is updated with access control data that has been programmed on the credential using a LenelS2 NetBox access control system.
