Light curtains for elevator door edges have been the established technology for protecting passengers from door impacts for many years. Their usage is described in the relevant codes in many regions and some basic light curtains can meet the standards.
LCD display installations are becoming much more popular when replacing traditional dot matrix displays. With the growth of LCD displays there is clearly an improved visual benefit as you can display richer graphical content but there is also the opportunity for advertising on screens. This can be specifically targeted at demographics based on the installation space.
Lift emergency phone regulations require that emergency-communication phones be available at all times for lift passengers in the event they become trapped in a lift. Traditionally this requirement is met with the employment of fixed landlines as the means of transmission for lift emergency phones.
With the evolution of cellular technology, the case for employing mobile phones in elevator communications has become compelling. In this article, we address many common concerns regarding the use of cellular to provide service to elevator emergency phones.
The Radio Equipment Directive (RED) establishes a regulatory framework for “making available on the market” and “putting into service” radio equipment in the European Union. It replaced the prior directive (R&TTE 1999/5/EC) and was effective 13 June 2017.
Over seven billion SIM cards are in active use globally making them the most widely used security token in the world. Over-the-air (OTA) updates can be deployed by SMS which allows the SIMs to be updated remotely. However, lift engineers have concerns relating to SIM hacking which could mean soaring premium rate bills.
Vandalism is a major concern for lift owners; damage through misuse and abuse impacts both the availability of lifts, and passenger safety. EN81-71:2005 is a harmonised European Standard which outlines additional protective measures to improve the vandal resistance of lift installations.
When selecting a suitable light curtain for your lift door safety application it is important to consider several factors before making your decision. Diode count, number of beams and response time all play a part in determining the relative performance of a particular detector, and no feature should be judged in isolation.
As of September 2017 all new lifts must comply with EN81-20 and EN81-50 Elevator Standards. These standards were approved in 2014 to replace EN81-1 and EN81-2, and after a grace period for the elevator maintenance and installation industry to prepare, these elevator standards are now mandatory for all new lifts.
In August 2014 two new standards covering lift design (EN 81-20:2014) and installation requirements (EN 81-50:2014) were released in Europe. These replace EN 81-1:1998+A3:2009 and EN 81-2:1998+A3:2009, which were 15 years old and needed upgrading to comply with modern safety requirements. It is expected that the new standards will also be adopted in China, South America and Australia.
