Electric Door Strike DR‑99NF‑512/S22 – 12 V DC Fail‑Safe Access Control.

The DR‑99NF‑512/S22 is a high‑reliability electric door strike designed for secure access control and door automation systems. Manufactured by Dorcas, this flush‑mount door opener features a fail‑safe (NC) operating mode, meaning the strike holds the door locked when powered and releases it when power is removed — ideal for emergency exit routes and access control integration. 

Built from robust steel with a gray protective coating and a narrow‑body design, the DR‑99NF‑512/S22 is well‑suited for frames with limited space such as aluminum or metal profiles. With an adjustable radial latch and a holding force of up to 330 kg, it provides secure locking performance for a wide range of single‑door installations.
