Usage
The Serrure A-P autoverrouillant ES21 55/72/8/24rd is designed for single-point locking of exit and emergency doors in public buildings, ensuring compliance with safety standards, especially where panic function E is needed for left-hand/DIN R installations.
Advantages
- Automatic relocking enhances security by securing the door after each closure[2].
- Panic function E enables immediate unlocking from inside for safe emergency egress[2].
- Compliant with DIN 18251 class 3 and EN179 standards, suitable for public access and escape routes[1][2].
- Durable construction: reinforced metal follower (8 mm), solid nickel-plated latchbolt and deadbolt[1][2].
- Restricted rotation angle (35°) minimizes mechanical wear; absence of strike plate may require separate purchase[2].
Specifications
- Design: Single-point notch lock with interchangeable rounded faceplate (24 mm), compatible with cylinder PZ, left-hand/DIN R opening direction. Body built from robust metal alloys; stainless steel finish.
- Durability & Certifications: Classified DIN 18251 class 3; suited to frequent use in high-traffic or evacuation settings. Meets requirements of EN179 for emergency exits[1][2].
- Main Dimensions: Backset: 55 mm; Centres: 72 mm; Follower: reinforced metal, square section of 8 mm.
- Differentiating Features: Integrated panic release mechanism disengages both latchbolt and deadbolt via handle operation from the inside—even if double locked—while automatic relock function engages upon door closure. Strike plate not included; compatible accessories available separately.
How it works
The user secures the door by simply closing it—the lock automatically engages both latch and deadbolt mechanisms. From inside, pressing the handle instantly retracts all bolts regardless of double-lock status to enable quick exit in case of an emergency. Access from outside requires a key at all times.
