General Information - Alarm Exchange Transactions (ALQ/ALR)
Overview
The purpose of the Alarm Exchange Transaction is to help provide a standard message key for electronically transmitting information between an Alarm Monitoring Company and a Public Safety Answering Point (PSAP). There are three primary uses for this transaction:
- Initial notification of an alarm event
- Bi-directional update of status between an alarm monitoring company and the PSAP
- Bi-directional update of other events between an alarm monitoring company and a PSAP.
This message key and its schema/format is endorsed by the Central Station Alarm Association (CSAA) as the standard for data exchange between alarm monitoring stations and PSAPs.
The standardization of this message is maintained by The Association of Public-Safety Communications Officials (APCO) and Central Station Alarm Association (CSAA).
Additional documentation on this message key can be found at National Information Exchange Model Tools > Welcome (gatech.edu)
Additional information on APCO can be found on their website http://www.apco911.org/
Because of the unique requirement to provide the standardized XML to/from PSAPs even through legacy switches, Nlets will not edit the payload and instead treats the embedded APCO XML as a text string.
