New EAO Door-Opener is "First Choice" for Train

Milford, CT – EAO Corporation of Milford, CT USA, a premier global supplier of Human Machine Interface (HMI) Systems and Components, unveils the new Series 57 ‘all-in-one’ door-opening pushbutton, which redefines the standard for passenger access.

Representing the latest in technology, the Series 57 is the first door-opening pushbutton to combine optical, tactile and acoustic features in a single, ground-breaking product.

Product Manager, Marco Bighi, says, “Our new Series 57 should be the first choice for any train operator to fully comply with EN 14752. EAO has a reputation for high-quality, innovative, passenger-access products, and now Series 57 will set a new standard.”

The modern design features a user friendly, extra-large operating area of Ø74mm, which includes two unique, independently-illuminated feedback rings. The raised symbols conform to TSI PRM (Technical Specification for Interoperability for Passenger with Reduced Mobility) and ADA (Americans with Disabilities Act – Accessibility Guidelines for Transportation Vehicles) and will never wear or fade. Options include illuminated symbols and an integrated ‘finding tone’ to help visually-impaired passengers.

Offering outstanding durability, the Series 57 is constructed using contemporary materials and will continue working through extreme temperatures from – 40º to +85ºC. The front is protected to IP69K against liquid and dirt ingress, and will resist chemical wash-downs often found within these application environments.

To save both time and money, EAO has designed a new and efficient final-mounting system. The pushbutton fits industry-standard mounting holes therefore allowing vehicle operators to easily upgrade their existing door openers to the new Series 57.

Series 57 – the only ‘all-in-one’ door-opening pushbutton with optical, tactile and acoustic feedbacks to meet EN 14752.
