CONTENT BUILDING INTERFACES FOR ELEVATORS AND ESCALATORS

 ELEVATORS : EN 81.1 – 1998 + A3-2010 and now EN 81-20 the new code  ESCALATORS & MOVING WALKS : EN 115-1 : 2008 + A1-2010

Company Proprietary & Confidential

THE NEW EN 81-20 & 81-50 • August 7th 2014, new EN standards EN 81-20 & EN 8150 were published giving the design requirements to comply with the Lifts Directive. • They make significant improvement to the safety of lifts by applying new or improved technical requirements for lift design. • From August 31st 2017, all handed over units will have to comply with these new frame of standards. • Otis commitment to safety is such that we have decided to implement these changes on our whole product range one year before this deadline in order to further safeguard our passengers and engineers. 2 Company Proprietary & Confidential

THE NEW EN 81-20 & 81-50 Why new Norms ?

What is the timing ?

New codes are replacing EN 81-1 and EN 81-2 codes issued in 1998, enhancing the standard in terms of safety, comfort and robustness for new elevators :

EN 81-20 and EN 81-50 were published on August 7th 2014 and be enforced starting August 31st 2017.

- EN 81-20 lists the safety requirements for lift installation - EN 81-50 defines calculations, examinations and tests of lift components

IMPORTANT: from August 31st 2017, all units handed over to customers have to be compliant with these new codes. There will not be technical solutions to retrofit an EN 81-1/2 compliant unit to an EN 81-20/50 one. So, all projects to be delivered in 2017 should account for this new code. 3

WHAT’S THE CHANGE OVERHEAD  Refuge spaces increased  Additional warning labels on top of car to indicate the required stance in the emergency position for maintenance personnel  Modification of the balustrade mechanical strength and size according to gap between hoistway wall and balustrade.

IN CAR  Brighter car light and emergency light  Door protection system with light curtain  Wider emergency exits  Increased fire resistance of car body panels and car door  Increased robustness for car body and car doors  Increased car apron mechanical strength  Prevention of car doors being opened away from landings  Unintended Car Movement Protection (UCMP) device is now considered as a safety device of the elevator, according to the new lifts directive. 5 Company Proprietary & Confidential

WHAT’S THE CHANGE IN HOISTWAY  Inspection speed limited to 0.30 m/s  Improved lighting in shaft (50 lux at 1 m on top of car and pit, 20 lux minimum on other locations & car top emergency light).  New standards addressed for electrical protection.  Changed responsibilities for shaft ventilation.  Increased robustness for panels of glass shaft.

AT LANDING  Modification of door lock position  Increased robustness for doors panels

IN PIT      

Refuge spaces increased Improved mechanical strength of counterweight screen Buffer deceleration rate modification New pit ladder definition Access by door at pit level when pit is deeper than 2.5m Company Proprietary & Confidential Pit control station

WHAT’S NEW FOR THE PASSENGER Mains improvements for COMFORT CAR LIGHTING Improved from 50 lux to 100 lux at 1 m above floor level. Feel safer with better lighting. EMERGENCY LIGHT IN CAR 5 lux for 1 hour duration. In case of entrapment, passengers don’t stay in the dark. DOOR PROTECTION SYSTEMS Non-contact light curtain mechanism. No more Photocell based mechanism. Reduces risk of passenger being struck while entering or exiting the car.

Mains improvements for SAFETY WIDER EMERGENCY EXIT On car roof or side panels: Assistance to entrapped passenger in car is easier and safer both for mechanics and passengers. MODIFICATION OF FIRE RESISTANCE RATING OF CAR LININGS Reduces risk of fire inside the car. MODIFICATION OF ROBUSTNESS For glass shafts: Reduce risk of injury in case of shaft glass break and fall into the shaft.

INCREASED CAR APRON MECHANICAL STRENGTH NEW CALCULCATION METHOD FOR SOME Reduce risk of injury & falling into shaft during an COMPONENT emergency rescue when the elevator is not at a Guide rail for instance. Better comfort and ride landing operation. 7 quality. Company Proprietary & Confidential

OTIS SOLUTION FOR COMPLIANCE Impacts of new standards on OTIS products

Impacts of new standards on building projects

GLOBALLY ENHANCING SAFETY LEVEL ON ELEVATORS, WITH MINOR IMPACT ON OTIS PRODUCT DESIGN.

WIDER REFUGE SPACES AT HEADROOM AND PIT OF SHAFT.

85 % of the new safety rules were already present on OTIS products. 2 examples: - Common button on inspection control station - Deterrent device

There are no significant impacts on OTIS shaft minimum dimensions. BALUSTRADE UPDATED HIEGHT REQUIRMENTS

OTIS’s expertise in door and car panels manufacturing covers complete value chain from engineering, testing, manufacturing and installing.

If the distance between the wall & the interior of the balustrade handrail is greater than 500 mm, then a 1100 mm balustrade height has to be installed on top of car, instead of a 700 mm balustrade for a distance lower than 500 mm.

FROM AUGUST 31ST 2017, ALL UNITS HAVE TO BE COMPLIANT WITH THE NEW REGULATION.

SHAFT VENTILATION IS A REQUIREMENT TO BE FULFILLED BY THE CONSTRUCTOR.

OTIS decided to raise safety standards ahead of time. From September 1st 2016, one year in advance.

OTIS’ major asset is the OTIS Pulsair solution, allowing to avoid the opening at top of shaft.8

INCREASED ROBUSTNESS FOR DOORS & CAR PANELS.

SHAFT : GENERAL REQUIREMENT Height between floors The rule for no more than 11m between floors is unchanged, except for Fire Fighting lifts which must have not more than 7m between floors. Ventilation Due to different rules for ventilation found within the Building Regulations in each European country, it is not possible for the standard to give guidance on this. Therefore the ventilation of this building space should be treated as any other and becomes the responsibility of the building designer. However, the manufacturer should specify the heat output of the equipment to be dealt with.

Company Proprietary & Confidential

SHAFT : GENERAL REQUIREMENT Where there are accessible spaces under the pit a safety gear must be provide on the counterweight. It is no longer permissible to use a “solid pier” as a means of protection. Where the pit is more than 2.5m deep, the access to the pit must be by a door at pit floor level. It is not acceptable for an engineer to climb down a ladder more than 2.5m without some means of fall protection. This will have an enormous effect on the design of the building.

SHAFT : STRENGTH  All glass used in the well must be laminated. The previous requirement was only where the glass was considered as accessible, but now it is anywhere in the well.  There are new requirements for strength of walls, doors and pit floor.
