scope:

This European Standard specifies requirements for SPT used in I&HAS to transmit alarm and other messages to a location remote from the supervised premises. NOTE 1 Requirements for the transmission of alarms are given in EN 50136 (all parts). prEN 50136-2 gives requirements for SPT for use in any type of alarm system (e.g. fire, social care, intrusion, etc). This European Standard gives specific requirements for SPT used in Intrusion and Hold-up Alarm Systems (I&HAS) and should be used in combination with prEN 50136-2.The requirements of this European Standard apply to different types of SPT including separate SPT, SPT located within the housings of other I&HAS components and also when the SPT functionality is integrated with the CIE or other parts of an I&HAS. NOTE 2 To facilitate the differing requirements this European Standard includes a categorisation with three types (X, Y and Z).This European Standard does not give requirements for the ATS network or performance.
