FAQs

1. What makes the 3782ELSS suitable for narrow doors?
   The 3782ELSS features a 23mm short backset specifically designed for narrow stile door frames such as aluminium commercial doors. Standard mortice locks are usually too large for these doors, so the slimline design allows installers to fit an electric locking solution without modifying the door frame.
2. What does power-to-lock and power-to-open mean?
   Power-to-lock means the lock remains unlocked until electrical power is applied, while power-to-open means the lock remains locked until power is applied to release it. The 3782ELSS can be configured to operate in either mode depending on the security requirements of the installation.
3. Can this lock be integrated with an access control system?
   Yes. The 3782ELSS is designed for use with electronic access control systems and can be operated by push buttons, intercoms, key switches, card readers and keypad entry systems. This allows authorised users to unlock the door electronically while maintaining secure mechanical locking when not activated.
