Digital Communication Standard - Ademco ® Contact ID Protocol - for Alarm System Communications

FOREWORD

This standard documents a communications protocol that was developed and is wholly owned by ADEMCO Group,

a division of Pittway Corporation . It is published by the Security Industry Association (SIA) as a de facto security

industry standard. It is intended to facilitate product compatibility and interchangeability, to reduce

misunderstandings between manufacturers and purchasers, and to assist purchasers in obtaining the proper products

to fulfill their particular needs.

The existence of this or any SIA standards document shall not prevent any SIA member or non-member from

manufacturing, selling, or using products not conforming to this or any SIA standard. SIA standards are voluntary.

SIA encourages the use of this document but will not take any action to ensure compliance with this or any other

SIA Standard.

Neither SIA nor Ademco assume any responsibility for the use, application or misapplication of this protocol.

Although some SIA standards establish minimum performance requirements, they are intended neither to preclude

additional product features or functions nor to act as a maximum performance limit. Any product, the specifications

of which meet the minimum requirements of a SIA standard, shall be considered in compliance with that standard.

Any product, the specifications of which exceed the minimum requirements of a SIA standard, shall also be

considered in compliance with the standard, provided that such product specifications do not exceed any maximum

requirements set by the standard. SIA standards are not intended to supersede any recommended procedures set by a

manufacturer for its products.

Ademco reserves the right to revise this protocol at any time. Users of this document are cautioned to obtain and

use the most recent edition of this standard. Current information regarding the revision level or status of this or any

other SIA standard may be obtained by contacting SIA.

Requests to modify this document are welcome at any time from any party, regardless of membership affiliation

with SIA. Such requests are to be made in writing, clearly identifying this document and the text within it related to

the proposed modification, and include a draft of the proposed changes with supporting comments. Requests for

new Event Codes are to include a description of the event to be reported as well as a short justification. Submission

of requests are to be accompanied by the name, phone number, and e-mail address (if available) of the person

making the request. Requests are to be sent directly to Ademco, preferably by email, care of:

Rich Hinkson: Rich_Hinkson@ademco.com

Bob Orlando: Bob_Orlando@ademco.com

Decisions to modify this protocol are at the sole discretion of Ademco, and Ademco reserves the right to deny

requests. When a decision is made regarding a request for modification, Ademco will notify the requestor.

Whenever a modification is made to this protocol, Ademco will inform SIA so that SIA may update this document

and notify other interested parties. Ademco may, at its discretion, also maintain a current list of Event Codes for this

protocol on its web site: http://www.ademco.com

Written requests for interpretations of this standard and other matters of document publication should be addressed

to:

ACKNOWLEDGMENTS

This document was developed by Richard Hinkson of the ADEMCO Group, a division of Pittway

Corporation .

The Ademco “Contact ID” protocol has become a prevalent and respected format for digital

communications between security alarm systems and central monitoring stations. Many manufacturers

have adopted it, seeking industry wide compatibility.

SIA gratefully acknowledges Ademco’s generous contribution to communications in the security

industry, both in allowing SIA to publish this protocol as a de facto security industry standard and in

accepting industry requests for modifications.
