Dormakaba 137 RR 24 Vdc Symmetrical Electric Strike without Faceplate per piece

Usage

The Dormakaba 137 RR 24 Vdc electric strike with symmetrical housing is designed for secure and remote-controlled access to doors in commercial or residential buildings. Suitable for integration into access control systems.

Advantages

• Symmetrical housing allows flexible, non-handed installation on either side of the door.
• Operates with continuous current at 24 Vdc, ensuring reliable functionality in demanding environments.
• Permanently energized operation (100% duty cycle) supports intensive use without overheating risk.
• Integrated potential-free micro-contact (RR) provides real-time door status monitoring ("door open/closed" feedback).
• No faceplate included, allowing compatibility with custom or existing door frame solutions; this may require selection of a suitable faceplate separately.

Specifications

• Design: Symmetrical case for position-independent installation; compact size suits various frame types and tight spaces[1][7].
• Materials: Robust construction engineered for long-term durability and resistance to wear[1].
• Circuit: Powered by direct current at 24 Vdc; supports continuous operation (100% ED)[7].
• Status Contact: Integrated RR-type signal contact (potential-free) outputs “door open/closed” information to building management or security systems[7].
• Differentiating Feature: Designed without pre-mounted faceplate, ensuring high compatibility with customized installations or replacement projects[7].

How it works

This electric strike remains locked until it receives a release signal from an external control device (such as an intercom or access system). When activated via a constant DC power supply, the mechanism releases the latch, enabling authorized entry while recording status through its integrated contact relay.
