Alarm Transmission Standards
A new Australian standard exists in relation to alarm transmission systems, and selection of a transmission system is dependant upon the level of risk for your premises. The standards are not based on the technology used, but rather on different aspects of transmission – including the frequency of connection checks, and annual network availability.
To comply with the class:
1. The communications / polling between the alarm panel and the communications device must mirror the communications polling to the Monitoring Centre.
2. An ADSL / Broadband router / modem must be battery backed up (UPS) to comply with the annual availability percentage.
