At present, the main requirement which is associated with projects or the maintenance of Residential Complexes, Communities of Buildings, Commercial or Industrial Offices, is the solution of access to the premises. These projects require effective systems for personal traffic and access control. For this reason FERMAX has developed a series of units which are divided into 2 application groups: STAND-ALONE AND DIGITAL. Those required for the control of 1 access are considered as STAND-ALONE, and when there is more than one access to be controlled within the same complexed and with the option of placing restrictions on times, gates and days of the week, they are considered as Digital.
