The 28SA-Plus-SM is a highly sophisticated, yet simple-to-use card access control unit for single or multi-door applications. The unit may be programmed with a PC terminal program, either locally or with the use of a modem. Basic programming functions can also be accomplished by using programming cards. Transaction information is stored by the unit and may be downloaded to a PC or serial printer. Up to 128, 28SA-Plus units can be connected together in a single twisted pair RS-485 network using the included RS-485 cable and SK-NETTM Software for Windows XP/Vista.
The Limited Use feature allows up to 4000 cards to be programmed to work for up to 500 uses, days, weeks, or days after the first use. The 28SA-Plus has 15 Access Control Time Zones and one door-unlock Time Zone. Each time zone covers a full week of access control plus Holidays in ½-hour segments. Daylight Saving Time is selectable to meet new or future requirements.
