The ADA-10/11 digital receiver module is used in applications where secure control of remote loads such as door strikes are required. Up to 16 ADA-10/11 receivers can be multidropped from one card reader. The sender in the card reader encodes the control information into a digital data stream which is decoded by the ADA-10/11 modules. Each module must recognize its unique address before switching its electrical load. Up to 16 unique addresses are sent to the ADA-10 receivers. In most access control systems the wiring between the door strike and the card reader controller is vulnerable to attack. An intruder need only apply a voltage or ground at this point to control the strike. The ADA-10 prevents control of the door in this fashion, since an encoded digital signal is required to control the strike. The ADA-10/11 can be mounted in a protected area near the strike with only the digital encoded signal going to the strike location. Thus control of the strike is removed from the reader and protected between the access controller and the strike. The design of the ADA-10/11 module allows easy retrofit of existing installations. The ADA-10 units are sealed, potted and take very little space and ADA-11 are smaller circut boards secured in a plastic mount. The receiver can be mounted in the door frame behind or adjacent to the door strike. The unit address for the receiver is field configurable by use of jumpers extended from the potted unit.
