Overview
ISO 4190-5:2006 - "Lift (Elevator) installation - Part 5: Control devices, signals and additional fittings" specifies the control devices, buttons, indicators and additional fittings to be provided when a lift (elevator) is constructed and installed. The standard emphasizes accessibility for persons with motor and sensory disabilities and defines requirements for handrails, landing and car control panels, audible/visual signals and ergonomic layout. It applies to lifts of classes I to IV and VI (see ISO 4190‑1 and ISO 4190‑2).
Key topics and technical requirements
- Types of control systems: down collective (DC), full/directional collective (FC), destination-oriented (DO) and group lift operation; special rules for destination keypads and group management are covered (Annex A).
- Landing controls: number and marking of call buttons depending on control type (single button for DC, up/down buttons for FC). Accessibility marking (wheelchair symbol) for dedicated cars in a group.
- Button and indicator specifications: operating force 1–5 N (recommended 2.5–5 N); active part area min 280 mm² (recommended 490 mm²); minimum inscribable circle diameter 19 mm (recommended 20 mm); tactile/visual contrast and raised symbols (0.8 mm thickness); audible call feedback adjustable 35–80 dB(A) (recommended max 65 dB(A)).
- Car operating panel: floor buttons, alarm (yellow bell or HELP), door re-open/close symbols, STOP device. Button layout rules, vertical/horizontal ordering and recommended mounting heights (e.g., button centreline 890–1 220 mm, recommended 900–1 100 mm).
- Sequential step scanning: required where car buttons are placed more than 1 220 mm above the car floor to allow floor selection by up/down scan buttons.
- Handrails: minimum requirements when handrails are provided in the car.
- Annexes: Annex A (normative) on special systems (e.g., destination controls), Annex B (informative) on particular access requirements, Annex C (normative) representative symbols.
Applications and users
ISO 4190-5 is used by:
- Lift/elevator manufacturers and designers for control panel design, button specification and human-machine interface.
- Installers and contractors for compliant installation and commissioning.
- Building architects, accessibility consultants and facility managers for design coordination and accessibility compliance.
- Regulators and standards bodies for reference in building codes and accessibility regulations.
Practical uses include new lift specification, retrofit planning (controls and signage), accessibility audits and procurement of compliant components.
