SIA: Security Industry Association

SIA, the Security Industry Association, is a nonprofit organization that develops and publishes standards for the electronic security industry. Headquartered near Washington, D.C., United States, SIA influence is present on Capitol Hill, throughout the 50 states and across the world through its approximately 400 members. In addition to developing SIA standards, SIA is heavily involved in government relations and large-scale international market research. Standards from SIA are available both individually, directly through the ANSI webstore, and as part of a Standards Subscription. If you or your organization are interested in easy, managed, online access to standards that can be shared, a Standards Subscription may be what you need - please contact us at: StandardsSubscriptions@ansi.org or 1-212-642-4980 or Request Proposal Price.

SIA AC-01-1996.10

Access Control Standard Protocol for the 26-bit Wiegand TM Reader Interface

The specifications in this standard define a commonly used interface between card readers and control panels used in the Access Control, Security, Time and Attendance, and other related industries. The standardization of the interface makes the design of readers and control panels uniform for manufacturers and makes system design and integration systematic for architects, designers, specifiers and users.


ANSI/SIA PIR-01-2000

Passive Infrared Motion Detector Standard - Features for Enhancing False Alarm Immunity

The standard details recommended design features for passive infrared detectors to reduce the incidence of false alarms when the detectors are used in security systems. Passive infrared detectors include detectors that incorporate passive infrared elements with other technologies.


SIA DC-03-1990.01 (R2000.11)

Digital Communications Standard - "SIA Format" Protocol - for Alarm System Communications

This specification describes a standard for digital communication to be used in the alarm industry, with possible future uses in the areas of energy control and facilities monitoring and management.


SIA DC-07-2001.04

SIA Digital Communications Standard - Receiver-to-Computer Interface Protocol (Type 2) - for Central Station Equipment Communications

This standard describes an interface format for communications between alarm signal receivers and automation computers. This standard is intended for use by equipment in security industry alarm monitoring centers, with possible uses in the areas of energy control and facilities monitoring and management.


ANSI/SIA MSD-01-2000

Mobile Security Devices Standard - Monitoring Practices for False Dispatch Prevention

This standard details the monitoring center operations and procedures accepted by the security industry as necessary to ensure a minimum of erroneous requests for public safety response. This standard is intended to provide a basis for self-regulation of entities that monitor MSDs and entities that provide products that are used for the monitoring of MSDs; and to establish criteria for the responsible use of MSD technology as it relates to interactions with public safety response agencies. This standard is intended for implementation by all entities that are involved with the monitoring of MSDs. It is meant to serve as a model for elaboration and incorporation into the policy and procedure of individual monitoring centers.


SIA AV-01-1997.11

Audio Verification Standard - Protocol for Audio Verification and Two-Way Voice - Monitoring Service Command Set

This standard describes the minimum requirements for command sets for a monitoring service operator pressing buttons on a touch-tone phone to control an audio verification system at the customer's premises. The monitoring service operator generates dual-tone multi-frequency (DTMF) signals by pressing buttons on a touch-tone phone connected in parallel with the monitoring service receiver's phone line. The audio verification system at the premises receives and interprets these signals.


SIA DC-04-2000.05

Digital Communications Standard - SIA 2000 Protocol for Alarm System Communications

This is a standard that specifies a communication protocol that will support current and future needs over a diverse range of control and receiver types. Specifically the intent is to define a flexible, universal, extensible reporting message format that can be used across a wide variety of physical media and transfer protocols. This SIA 2000 protocol structures the communication between a control and a central station receiver. The basic form of this communication conveys information such as alarms, alarm cancels, troubles, and restorals. This involves transferring information records from the control to the central station, and receiving acknowledgments from the receiver for each record. To support features such as remote panel programming and alarm verification through audio or video means, the protocol has provisions to extend the communication session. Once extended, the receiver can query the control for information or change the control's configuration. The extended session can also be used for verification.
