The 28SA Plus is a highly sophisticated, yet simple to use, card access control unit for single or multi-door applications. Simply place the card on the stainless steel TOUCH CARD® Reader plate, and the card is read instantly and accurately. Patented slotless TOUCH CARD® Reader technology protects the unit from weather and vandalism.

The unit may be programmed with a PC 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 printer. Up to 128 28SA Plus units can be connected together in a single twisted pair RS-485 network using optional Modules and Software for Windows® 95/ 98/NT/2000.

A remote reader may be connected to the 28SA Plus to allow access control in both directions through a single passageway, including true IN/OUT anti-passback capability. Three inputs are provided which are user programmable as Door Monitor, Tamper Monitor, Remote Inactive, Remote Open, Arming Circuit, Bell, or User Defined. The limited use feature allows cards to be programmed to work for a specified number of uses, days, weeks, or days after the first use.

The SA28 can be configured to work in both a online and offline scenario. This access controller / reader combo can be used in a 2 lane system with true or time anti-passback. The SA28 can also be used in a single lane, stand alone, offline proximity reader system with up to a 3' read range.
