ATE: Alarm transmission equipment.
SPx (Single Path): A value that indicates the performance level achieved by a single
communication device, according to the EN 50136–1 standard.
DPx (Double Path): A value that indicates the performance level achieved by a combination of
two communication devices, according to the EN 50136–1 standard.
Reporting time: The reporting time is prescribed based on the standard of each level of
performance. Reporting time is the maximum time available to report when an alarm
transmission device fails. Alarm transmission devices meet this requirement by regularly
reporting their status through a specific symbolic test function.
Protocols: Indicates the security level of the protocols to be used for the notification of failures.
Standard protocols and voice protocols are encrypted. High security protocols are encrypted with
an AES 128 bit or AES 256 bit encryption key.
Communication devices: Implemented communication devices.
Communication devices to be used: Indicates the number of and which communication devices
are to be used based on the ATE category.
