## Long description

Siemens S24UM electric strike from the HARTTE XS series is a monitored door locking device designed for 24 V AC/DC supply. It is intended for integration in access control, intercom and door release systems where remote unlocking and contact-based status feedback are required. The electrically actuated latch allows controlled opening of doors while preserving the mechanical function of the lock, and the monitoring contacts report the strike status to security or automation controllers.
Advantages
The monitored electric strike provides reliable remote unlocking with integrated status feedback for improved security monitoring. Its 24 V AC/DC compatibility ensures flexible installation with common power supplies used in access control systems. The HARTTE XS design prioritizes compact mounting and maintains mechanical lock operation when power is absent, providing fail-secure or fail-safe behavior depending on system wiring. Monitoring contacts simplify integration with alarm panels and intercoms, enabling real-time detection of door state and unlocking events.
Suitable for
 Access control systems in commercial and residential buildings
 Intercom and video-door phone installations requiring status feedback
 Security systems and alarm panels that need monitored door releases
 Door entry points where remote release and condition monitoring are required
Key specifications
 Supply voltage: 24 V AC/DC compatibility for flexible power options
 Monitored contacts: built-in status feedback contacts for lock/release detection
 Mechanical interface: electric strike format compatible with standard latch locks to allow mechanical operation when not energized
 Mounting: compact design for flush or frame mounting in commercial door frames
 Function: remote electrically actuated latch release suitable for controlled access
How to use
Install the electric strike in the door frame aligned with the existing latch according to door type and frame material. Connect the 24 V supply and the monitoring contacts to the access control or intercom system following the wiring diagram provided by the installer or system manufacturer. Configure the access controller to energize the strike for door release and to read the monitoring contacts for status and fault detection. Verify mechanical alignment and test both remote unlocking and contact reporting before finalizing the installation.
Usage recommendations
For reliable operation, use a stabilized 24 V AC or DC power source sized to the installation and follow manufacturer guidelines for wiring and protection. Regularly inspect alignment and contacts, and test monitoring signals as part of scheduled maintenance to ensure correct integration with access control and alarm systems.
