FAQ — Frequently Asked Questions
Door closer is essential in Access Control System for several reasons: 1) correct electric lock operation — lock closes only if door is fully closed, closer ensures this, 2) security — door always closes and locks, doesn't stay open, 3) energy efficiency — closed door maintains temperature, 4) comfort — requires no manual closing. Without closer, electric lock won't work correctly.
Closers are classified by EN 1154 standard by force (EN 1-7): EN 1-2 — 20-40kg (light doors, internal offices), EN 3-4 — 40-80kg (standard doors, most common), EN 5-6 — 80-120kg (heavy doors, entrances), EN 7 — 120-200kg (very heavy doors, fire-rated). Measure door weight and select corresponding EN class. Wrong choice leads to rapid wear or insufficient force.
Yes, electromagnetic Hold-Open closers integrate with fire alarm — door is fixed in open position by electromagnet, and when fire alarm activates, electromagnet releases and door automatically closes (fire-rated doors, evacuation routes). This is mandatory for EN 1154 and fire safety standards compliance. Integration with access control (remote release) is also possible.
