Dormakaba 117 RR Symmetrical Electric Strike 24 V DC Without Faceplate per piece

Usage

The Dormakaba 117 RR 24 Vdc symmetrical electric strike is designed for secure, remote-controlled door unlocking in access control systems, suitable for standard inward or outward opening doors in commercial and institutional buildings.

Advantages

• Symmetrical housing allows easy installation for both left- and right-handed doors.
• Equipped with a built-in signal contact (RR) to provide door status feedback (open/closed).
• Operates on safe, low-voltage continuous power (24 Vdc, 100% duty cycle) for reliable performance.
• Contact stationnaire feature: remains unlocked after impulse command until the door is opened.
• No mechanical release lever included; keeps operation simple but disables manual unlock from the strike side if needed.

Specifications

• Design: Symmetrical body without faceplate (tétière), reversible for left/right door handing. Easy Adapt latch guide simplifies alignment during installation. Integrated protective diode limits surge effects on electronics.
  
• Status Signalization: Includes an RR micro-contact delivering “door open/door closed” information.
  
• Performance: Resists up to 3500 N force against forced entry. Operates on permanent direct current supply at 24 Vdc. Rated at a continuous operation duty cycle (100% ED).
  
• Differentiating Features: Compatible as an alternative to Eff-Eff series strikes; suitable for standard installations requiring electrical signal feedback without manual override or weatherproofing.
  

How it works

The electric strike unlocks remotely via a control pulse; the locking mechanism remains disengaged until the door is physically opened. The integrated contact transmits real-time status of the lock position to connected access control systems, supporting monitored and automated entry points.
