Simplex 2001-3048 P N I S Code Transmitter Module Description

2001 3048 P N I S Code Transmitter Description Fig 1 alarm conditions the 2001 3048 P N I S Code Transmitter Module transmits four rounds of code within seconds Each round can have up to 23 pulses normal rate or if programmed 46 pulses fast rate P N I S module contains 23 dip switches Sl 1 thru Sl 8 S2 1 thru S2 8 and S3 1 thru S3 7 which are used programming the desired code When a switch is set to the closed position a pulse is activated and when is set to the open position the pulse is absent pause Switch S3 8 is used to set the code rate open for normal rate 23 pulses maximum closed for fast code rate 46 pulses maximum P N I S module also contains the following indicator CODING COMPLETED Off when normal condition On when coding operation completed following an alarm activation REFERENCE P N I S module circuitry is shown on the following drawing WD No 841 551 P N I S Code Transmltter 1 0 1984 Simplex Time Recorder Co All rights reserved in the United States of America FbNCTION Refer 2 a conditions the zone module applies a V to pin Ml This voltage activates the P N I S module and pulses are sent out pins C OV pulses and E V pulses One of these outputs is tied to the system devices causing them to respond in accordance with the programmed code When 0V applied to 5 from the next highest priority coder the output pulses at pins C and E are inhibited the P N I S module is operating 0V OV is sent out pin 12 to inhibit the 1 st highest priority coder sent out pin J to inhibit the next lowest priority coder module and V IN FROM ZONE MODULE M ALARM OV IN WHEN ALARM FROM THE HIGHEST PRIORITY CODER TO OUTPUT OF CODED PULSES PINS C AND E OUT TO INHIBIT 1ST HIGHEST r 12 CODER WHEN CODING OV SYSTEM COMMON Oi PULSES CODED OUT SIGNALING DEVICES ALARM PULSES CODED OUT TO SIGNALING DEVICES ALARM OUT TO INHlBlT NEXT WHEN ALARM P N I S Code Transmitter 2 10 84
