This security system is designed to transmit data to a central station receiver when an
alarm, system trouble, or an opening/closing occurs. Due to the many different types of CS
receivers on the market, this system can transmit data in various formats. Each installing
company determines which format best suits its needs based on many factors. Of these, the
CS receiver type is a major factor.
Stage What Happens
1 The system’s digital communicator seizes the home phone lines. Then it dials the CS #1
telephone number (programming question 01).
2 When the CS receiver picks up the ringing phone line, it transmits a “handshake”
frequency (1400Hz, 2300Hz, or HiLo) back to the digital communicator.
3 After receiving the “handshake” frequency, the digital communicator transmits the data
in the format programmed in question 04 (either in Pulse or DTMF).
4 Assuming the CS receiver verifies the data transmission as valid (after 2 successful
rounds of data or 1 valid parity round), it transmits a “kissoff” frequency back to the
digital communicator. This causes the communicator to stop transmitting, unless more
data is available, in which case additional data transmissions and “kissoffs” occur.
5 After the final “kissoff,” the CS receiver releases the phone line and processes the data
to its display and associated peripherals (computer and printer). If for any reason the
digital communicator does not receive the “kissoff,” it proceeds to dial the CS #2
telephone number or to redial the CS #1 telephone number (if CS #2 is not used). It
continues to dial (8 times for each CS telephone number programmed) until a “kissoff” is
received. If, after dialing 8 times for each CS telephone number programmed, a “kissoff”
is not received, the system displays “Communication Failure” at the keypad. This
message is cleared after the next successful transmission or by the user at the keypad.
The following is a general description of the various formats transmitted by this system.
Standard (3X1 or 4X1)
The Standard Reporting Format: AAA E or AAAA E
Where:
AAAA = 3- or 4-digit account number (Program Questions 09 and 10)
E = Single-digit Event code; it is the first of the 2 programmable Reporting code digits
Standard format is transmitted in Pulse and involves a 3- or 4-digit account number followed
by a single-digit Event code. It can be transmitted with parity (1 round of data) or without
parity (2 rounds of data). A disadvantage of this format is that it can transmit only a total of
15 event codes (0 - 9, B - F) without identifying zones or users. Examples:
3X1 w/o Paritiy 3X1 w/Parity
123 3 (1st round) 123 3 6 (single round)
123 3 (2nd round) 123 3 (resulting data)
123 3 (resulting data)
4X1 w/o Parity 4X1 w/Parity
