There is a range of security alarm panels have a Securitel interface built in as a standard option, or a separate STU (Subscriber Terminal Unit) can be attached to any alarm panel.

The alarm panel is connected to a normal telephone service which has the Securitel features applied to it in the local exchange. The panel is polled by the scanner in the exchange for any change in status, which is then transmitted by dual paths to the Securitel Host computers and on to the Agency connection at CMS.

The use of Securitel as the transmission method is based on the risk assessment for the premises as contained in Australian Standard AS2201 Part1 (Systems Installed in Clients Premises), and the specifications and limitations are contained in AS2201 Part5 (Alarm Transmission Systems).

Securitel performs to AS2201.5:1992 (C3S2) as a Class 3 polled service and reports any cut in the phone line within 90 seconds.

A higher security option may better suit the Premises Risk and consideration should be given to the CMS MultiPath Class 4 or 5 option which also has a known fixed operating cost.

Securitel is available in major centres around Australia but is ending in 2009.
