Handle controlled locks are best suited in medium traffic doors. The locks can be electrically controlled by access control system or by a remote control system such as timer, keypad or push button. The locks can be used both in exit doors and fire rated doors. Handle controlled locks can be set to function as fail locked or as fail unlocked. In the fail locked setting, the lock can be opened by handle when power is on and cannot be opened by handle when power is off. In the fail unlocked setting, the electrical function is reversed. The locks are always automatically deadlocked when the door is closed. In EL480 the outside handle is electrically controlled. The lock can always be opened by the inside handle or by panic bar. In order to function correctly, the handle requires a split spindle. Mechanical opening by cylinder is always possible. Generally used in interior- and exterior doors of offices and business premises as well as the exterior doors of houses. Cannot be used in doors with door automatics.
