Command Access MLRK1-CAL77 Motorized Latch Retraction Kit for Cal Royal 7700 Series Exit Device

Convert existing Cal-Royal 7700 or PD26 exit devices into fully electrified latch retraction systems to improve building security and streamline access control integration. The Command Access MLRK1-CAL77 motorized latch retraction kit delivers a fast, low-impact retrofit that preserves UL listings while enabling remote latch pullback, electric dogging and optional request-to-exit functionality. Designed for installers and security integrators, the kit runs on 24V DC with a 900mA start current and supports wire runs up to 300' using 18 AWG, so you can place power supplies and controllers centrally for easier monitoring and networked security deployments. The upgraded MM4S smart module offers three energy modes (including a high-torque setting), audible diagnostics, and low-current operation to reduce power costs and simplify troubleshooting. Push-to-Set (PTS) technology provides five-second post-install adjustments, cutting service time and callbacks. Ideal for access control, physical security, and surveillance projects where reliability and minimal downtime matter, the MLRK1-CAL77 is backed by a 3-year No Hassle Warranty.
