Bottom line: ADA permits but does not require power-operated doors. Mechanical self-closing hardware meets ADA at non-fire-rated openings under 5 lbf. The specification shifts to electric when (1) fire-rated accessible doors create a force conflict, (2) infection control requires hands-free access, or (3) occupants have severe mobility limitations.
| Criterion | Mechanical | Low-Energy (A156.19) | Full Auto (A156.10) |
|---|---|---|---|
| Activation | Passive (spring/hydraulic) | Push plate or access device | Motion sensor |
| Safety sensors required | No | Not always | Yes — both sides |
| Installed cost / opening | $300–$600 | $2,500–$5,000 | $5,000–$15,000 |
| Annual maintenance | $50–$150 | $200–$400 | $400–$800 |
| 20-year TCO | $1,500–$3,500 | $6,000–$13,000 | $13,000–$30,000+ |
| Power required | None | 120V AC / low-voltage DC | 120V AC + battery backup |
| Fire door compatible | Yes (NFPA 80) | Yes (UL listed) | Yes (UL listed + fail-safe) |
| Feature | A156.10 (Full Power) | A156.19 (Low Energy) |
|---|---|---|
| Activation | Motion sensor (no contact) | Push plate / access switch |
| Max opening speed | ~30 in/sec | 18 in/sec (1.5 ft/sec) |
| Safety sensors | Mandatory both sides | Not always required |
| Typical use | Hospital main entries, retail, transit | Accessibility retrofits, senior living, hospitality |
| Key brands | Besam, Horton, Stanley Access, DORMA | LCN 2000, Norton 6000, dormakaba ED, GEZE |
| Occupancy | Specification | Reason |
|---|---|---|
| Healthcare — patient rooms | Low-energy A156.19 | Fire door force conflict; hands-free for staff with carts |
| Healthcare — OR/ICU | Full auto A156.10 | Infection control; no-touch required |
| Senior living — common areas | Low-energy A156.19 | Push-plate for limited-mobility residents |
| Hospitality — guestrooms | Mechanical | Non-fire-rated; 5 lbf achievable with hydraulic hinge |
| Commercial office — corridors | Mechanical | Low-force closer satisfies ADA; no electric needed |
| Commercial — public entry | Full auto A156.10 | High traffic; motion sensor expected |
Q: Does ADA require power-operated doors?
A: No. ADA §404.3 permits them but does not mandate them. Mechanical hardware meeting 5 lbf satisfies ADA at non-fire-rated openings.
Q: What is the difference between ANSI A156.10 and A156.19?
A: A156.10 = full-power automatic (motion sensor, high speed, mandatory safety sensors). A156.19 = low-energy (push plate, slow speed, sensors sometimes not required). A156.19 is the accessibility retrofit standard.
Q: Can mechanical self-closing hinges meet ADA on fire doors?
A: Not always. ADA exempts fire doors from 5 lbf, but the accessibility need remains. Low-energy operators solve the fire door/ADA force conflict.
Q: What does a low-energy door operator cost installed?
A: $2,500–$5,000 per opening installed (A156.19). Full automatic (A156.10): $5,000–$15,000. Mechanical self-closing: $300–$600.
Q: Which brands make low-energy operators for accessibility retrofits?
A: LCN, Norton, dormakaba ED series, Stanley Access, GEZE for swing doors. Besam and Horton for sliding entries.
Q: What is the ADA sweep period requirement?
A: Minimum 5 seconds from 90 degrees to within 3 inches of the latch. Slower is acceptable; faster is not.
Q: Do electric operators work on fire-rated doors?
A: Yes, with UL listing for the fire rating, fail-safe close on power loss, and integration with the fire alarm system.
