Power for communication between key and cylinder comes from a standard battery inside each key. There’s no mains power line to the cylinders, which means installing Cliq system needs no wiring—a big advantage for any public utility with lots of remote or outdoor openings.

Precision mechanics inside every Cliq cylinder guarantee durability. Cliq cylinders are compliant with EN1303, EN12320, and EN15684—and so offer high levels of protection against physical attack. They are IP rated, waterproof, and ATEX approved for use in potentially explosive areas.

“We’re convinced of the benefits of Cliq,” says Thomas Hug, project manager at Industrielle Werke Basel that upplies residents of Switzerland’s third-largest city with electricity, district heating, biogas and natural gas, and safe drinking water.

“Public utilities really push locks to their maximum,” says Christoph Oberle at Assa Abloy Switzerland. “Critical infrastructure sites are usually dispersed, and often outdoors—so locks must be reliable in all seasons. That’s why we precision engineer Cliq technology to the highest standards. Cliq can weather whatever nature throws at it.”

Cliq is also a practical and time-saving solution. If an employee or contractor loses their key, it’s straightforward for system administrators to delete its authorisation using the Cliq Web Manager software. Thanks to Cliq, IWB can wave goodbye to the expensive refitting of cylinders every time a vital key goes missing.
