Secure test in case of fire

If there is a fire inside, the door will be opened automatically for people inside to evacuate quickly. KS / KC standard: it will detect fire's high tem (65 -+ 5), door lock will get automatically opened

Fireproof technology

On fireproof door where digital door lock is installed, no fire should go outside not to be spread. All door locks are tested according to KC standard (in 1000 degree, non-thermal barrier, no fire should be seen from outside for more than 10 sec when fire was shot at for an hour)
