American Technical Support: 800-282-9855 Web Site: www.onsemi.com The S-ART is a 16 pin circuit designed for data transmission on a two-lead cable. The circuit is spe- cially developed for alarm systems where it is desired to identify each detector individually. There can be up to 30 S-ART circuits/detectors on the same 2-lead cable. This cable transmits both DC supply to the S-ART and information to/from the S-ART. The S-ART works on the principle by which an address is sent on the line cable and the S-ART which rec- ognizes the address then carries out the order which can, in principle, be two things: 1. Transmit data from the line cable to the S-ART's two outputs OUT0 and OUT1. 2. Answer the S-ART controller with the condition of the 2 inputs IN0 and IN1 or IN2-3. The line signal is divided into 3 lev- els in order to give a time signal for synchronizing and a data signal containing addresses, orders etc. Typical signal levels for the three levels would be 15V, 7.5V and 0V. Block Diagram Line 1 Controller Line N S-ART A method by which, in principle, the system can be extended to an infinite number of S-ART is shown on the block diagram. The controller scans the in/out- puts of a number of lines, each with a maximum of 30 S-ARTs. |
