SDC D7550LCQ-X-8204 HiTower Failsafe Frame Actuator Controlled Mortise Sargent Lockset, Locked from Outside

The SDC D7550LCQ-X-8204 is a frame actuator controlled left-handed lockset that is locked from the outside only and has a failsafe operation. The unit is equipped with a Sargent mortise lock, a standard failsafe actuator that operates at 24 VDC, and has a satin chrome finish.

SDC HiTower locksets comply with all national and regional building codes for locking interior office, elevator lobby, exit and stairwell fire rated doors, where the use of electric strikes and magnetic locks is prohibited. HiTower locksets also provide higher security and superior aesthetics compared to exposed and vulnerable electric strikes and magnetic locks, while eliminating the need for request-to-exit devices. While providing controlled access and remote control capability the door stays latched even when unlocked, maintaining fire door integrity.

The HiTower lock consists of a mechanical door lock controlled by an electric actuator installed in the frame. All access control and monitoring wires are maintained in the frame. Power transfer hinges and wires through the door are not required. All expenses associated with power transfer hinges are eliminated, including costs for door wire chases that must be factory prepared to maintain the doors fire ratings.
