Ademco ® Contact ID Protocol -
for Alarm System Communications

Back to table of Contents
This standard details the specification for the "Ademco ® Contact ID" communication format, originally developed by the Ademco Group, a division of Pittway Corporation.

The purpose of this standard is to detail the Contact ID signaling format such that it can be adopted by any manufacturer of digital transmitters or receivers.   Documentation and distribution of this communication format is intended to provide an across-the-board compatibility of equipment designed to this standard regardless of manufacturer. 

This communications format utilizes standard DTMF tones for transmission of the information.
1.1	  Objectives

a)	Provide information regarding events that are occurring on a customer's premises. This information should be in a form that can easily be interpreted by a central station operator.

b)	Spend minimum practical time on line per transaction, to minimize the number of receivers required to handle the traffic and minimize the time the line is seized and not available to the customer.

c)	Minimize the transmission error rate

d)	Minimize the cost of the hardware associated with the transmission of the information

This section describes the basic components of a communication session.

4.1	  Transmission Components

The transmitter to receiver communication session is composed of three basic elements: the Handshake Tone sequence, Message Blocks, and Acknowledgements. 

The Handshake Tone sequence consists of a pair of single-frequency tones sequenced in time. 

The Message Blocks consist of a series of DTMF tone bursts separated by spaces. 

The Acknowledgement Tone is a single tone burst.
4.1.1	Handshake Tones
The Handshake Tone sequence is produced by the RECEIVER. The purpose is to signal the TRANSMITTER that the communication channel is ready.	Placement
The Handshake Tone sequence is emitted by the receiver after going off-hook and delaying an interval of at least 0.5 seconds but typically no greater than 2.0 seconds. This time allows the phone network connection to settle before the communication process begins.	Composition
The handshake tone sequence shall consist of:
·	A burst of 1400 Hz. ±3% tone with a duration of 100 msec. ±5% 
·	A pause of 100 msec. ±5% 
·	A burst of 2300 Hz. ±3% tone with a duration of 100 msec. ±5% 

 Note:  Transmitters shall accept a frequency error of at least ± 5% to ensure back-compatibility with older receivers.

4.1.2	Message Blocks
A Message Block is sent by the TRANSMITTER for each message in the transmitter's message queue. Each message block contains sufficient information to report an event in the system.	Placement 
The first message block is sent beginning 250 msec. (250 min.,300 max.) after the end of either the Handshake Tone sequence or after a Kissoff (Acknowledgement) tone. The delay is timed from the end of the tone.	Message Composition
The form of the message is:



ACCT = 4 Digit Account number (0-9, B-F)

MT = Message Type. This 2-digit sequence is used to identify the Contact ID message to the receiver. It may be transmitted as either 18 (preferred) or 98 (optional). New receiver implementations shall accept either a 18 or a 98. Note that some older receivers may not accept 98 .

Q = Event qualifier, which gives specific event information:
	1 = New Event or Opening
	3 = New Restore or Closing
	6 = Previously reported condition still present (Status report)

XYZ = Event code (3 Hex digits 0-9,B-F)        

GG = Group or Partition number (2 Hex digits 0-9, B-F).  Use 00 to indicate that no specific group or partition information applies.

CCC = Zone number (Event reports) or User # (Open / Close reports ) (3 Hex digits 0-9,B-F ).  Use 000 to indicate that no specific zone or user information applies

S = 1 Digit Hex checksum calculated such that: 

(Sum of all message digits + S) MOD 15 = 0
Note:  A '0' shall be transmitted as a 10 and valued as a 10 for checksum purposes even though it is displayed and printed as '0'. It uses the same tone pair as the '0' (OPER) key on a standard telephone.	Data Tones
The message is sent using standard DTMF tones. 

The timing of the tones shall be as follows:

Burst ON time - 50 msec. (50 min.,60 max.)
Burst OFF time- 50 msec. (50 min.,60 max.)

The details of the tones are contained in the following table. 

Data Transmission Frequencies - 
Standard DTMF Signaling 

Digit	LowTone(Hz.)	HighTone(Hz. )	DigitValue
0	941	1336	10
1	697	1209	1
2	697	1336	2
3	697	1477	3
4	770	1209	4
5	770	1336	5
6	770	1477	6
7	852	1209	7
8	852	1336	8
9	852	1477	9
B (*)	941	1209	11
C (#)	941	1477	12
D	697	1633	13
E	770	1633	14
F	852	1633	15


1)	The digit '0' is transmitted with a value of 10 and shall be counted as a 10 in the calculation of the message checksum. 

2)	The DTMF pair of 941 Hz. And 1633 Hz. is not used in this format and shall not be sent.

3)	The frequency deviation on each of the above frequencies shall be ± 1.5% max.  Inter-Message Time
After sending its message, the transmitter should wait for 1.25 sec. for the start of a Kissoff Tone from the receiver. If the start of a kissoff tone is detected, the transmitter must continue timing the tone, even if the inter-message time expires. The panel must detect a minimum of 400 msec. of the Kissoff Tone for it to be considered to be valid. 
If a Kissoff tone is detected, the transmitter should wait for the tone to end and then wait 250 msec. (250 min.,300 max.) before beginning the next message.
If no Kissoff Tone is received, the transmitter should repeat the message after the expiration of the 1.25 second inter-message interval.

4.1.3	Kissoff (Acknowledgement) Tone
The Kissoff tone from the receiver is used to tell the transmitter that the message has been received successfully. The frequency of the tone shall be 1400 Hz. ±3% and shall be sent by the receiver for a minimum of 750 msec. and a maximum period of 1 second.
The transmitter must detect a minimum of 400 msec. of tone before considering the kissoff to be valid. 

Note: Transmitters shall accept a frequency error of at least ± 5% to ensure back-compatibility with older receivers

4.1.4	Maximum Number of Attempts 
The transmitter shall make up to 4 attempts to deliver a message before hanging up and redialing. The attempts counter is reset each time a valid kissoff signal is received.

4.2	 Data Codes

The data codes used to transmit events are contained in Appendix C: Event Codes.

Back to table of Contents

Example 1 - Alarm Message

Account 1234 is reporting a Perimeter Burglary Alarm on Zone 15 of Partition 1

The message shall be sent as:

1234 18 1131 01 015 8


1234	=	The account number  (1234)
18	=	The message type used to identify the message as Contact ID
1131	=	The Event Qualifier (1) for a new event, followed by the Event Code for Perimeter Burglary (131)
01	=	The partition number (1)
015	=	The zone number (015)
8	=	The checksum, computed in the following manner:

a)	Add all of the message digits together, using 10 for all '0' digits (1+2+3+4)+(1+8)+(1+1+3+1)+(10+1)+(10+1+5) = 52
b)	Find the next highest multiple of 15, in this case 60. 
c)	Subtract the sum from this value (60-52 = 8)
d)	Use the result for the checksum.. If the result is 0, use the digit 'F' (15) for the checksum.


Example 2 - Restoral Message

Account 1234 is reporting a Restore of a Perimeter Burglary Alarm on Zone 15 of Partition 1

The message shall be sent as:

1234 18 3131 01 015 6


1234 	=	The account number  (1234)
18 	=	The message type used to identify the message as Contact ID
3131    =	The Event Qualifier (3) for a restoral, followed by the Event Code for Perimeter Burglary (131)
01	=	The partition number (1)
015	=	The zone number (015)
6	=	The checksum (See Example 1)


Example 3 - Opening Message

User 3 disarms Partition 2 of Account 1234

The message shall be sent as:

1234 18 1401 02 003 5


1234 	=	The account number  (1234)
18 	=	The message type used to identify the message as Contact ID
1401   =	The Event Qualifier (1) for an Opening, followed by the Event Code for Open/Close by User (401)
02	=	The partition number (2)
003	=	The User number (003)
5	=	The checksum (See Example 1)


Example 4 - Closing Message

User 5 arms Partition 3 of Account 1234

The message shall be sent as:

1234 18 3401 03 005 F


1234	=	The account number  (1234)
18	=	The message type used to identify the message as Contact ID
3401	=	The Event Qualifier (3) for a Closing, followed by the Event Code for Open/Close by User (401)
03	=	The partition number (2)
005	=	The User number (003)
F	=	The checksum (See Example 1)

Note the use of 'F' since the sum of the message digits is an even multiple of 15.
