Easy Integration for Flexible Access Control

The RM1 module is specifically designed to facilitate compatibility between AC powered access control systems and DC reliant devices like Alpro’s range of electric door strikes. Facilities managers and contractors tasked with maintaining or upgrading older access systems will appreciate the ALPRO RM1’s easy-to-install rectification capabilities. By converting AC to DC power it eliminates compatibility issues that arise when adding modern components to legacy systems.

With a versatile input voltage range of 12-24V AC (+/-15%), the RM1 enables access control professionals to make existing infrastructure work with newer technologies. This is particularly valuable for high traffic facilities that need reliable access control solutions without disrupting current power setups. By reducing the current required for electric strikes, the RM1 also extends component life and lowers energy costs, making it a practical and economical choice.

The Role of Electric Strikes in Modern Access Control Systems

Electric strikes play a vital role in access control systems by controlling door latching mechanisms electronically. When paired with a rectifier sounder module like the RM1, these strikes gain the flexibility needed to operate with both AC and DC systems, allowing for secure and efficient entry management. 

Access control systems rely on electric strikes to enable or restrict access, making power compatibility a crucial element in a well-functioning setup. By adapting AC power to DC without the need for a full system overhaul, the RM1 empowers facilities managers to modernise their access control capabilities with minimal disruption.

The Purpose and Benefits of Access Control Systems

Access control systems are essential in safeguarding facilities, protecting sensitive areas, and ensuring controlled access. From commercial offices to healthcare settings, these systems help manage and monitor entry, providing security and peace of mind for both users and managers. With the RM1, facilities managers can enhance their access control systems’ adaptability, enabling them to work efficiently with AC power sources while supporting components designed for DC.
