The Electric Strike Promet HARTTE S12UW series S 12V AC/DC with switch is a compact door strike designed for access control systems that require a 12 V AC or DC power supply. The unit fits common strike cutouts and integrates an internal switch for feedback or signalling in locking systems. It is intended for installation in residential and commercial doors where remote release and electrical monitoring are needed.

Advantages

This electric strike supports both AC and DC 12 V supply, offering installation flexibility in different power environments. The integrated switch provides a contact signal for connection to an access control panel, alarm system, or intercom unit, allowing status monitoring and simplified wiring. The design conforms to standard strike dimensions to minimize frame modification during retrofit or new installations.

How to use

Install the strike into the door frame cutout according to the frame manufacturer’s guidelines and local electrical regulations. Connect the power leads to a 12 V AC or DC supply; observe correct polarity when using DC. Wire the integrated switch to the access control panel, intercom, or alarm input to provide a contact signal indicating latch status. After installation, test the release function and switch signal by activating the door release from the control device and by operating the door manually to confirm proper alignment and reliable operation.

Usage recommendations

Choose the 12 V supply type that matches your access control system and ensure a stable power source. During installation, verify mechanical alignment of the strike and the latch to prevent misoperation. For installations in high-traffic doors or where additional security is required, consider combining the strike with suitable electric locks and monitoring devices. Follow local safety and building codes, and if unsure, use a qualified installer to ensure correct wiring and secure mounting.
