The above information is based on the „Verbeterde Risicoklassenindeling VRKI 2007‟. For a full overview,
see
If all parameters have been set correctly the AlphaCom PSTN2IP ML can be used in AL0, AL1 and
AL2 situations. Voor AL3 situations a AlphaCom XL with a GPRS module must be used.
According to the EN50136-1-1 there are specific rules and regulations that also apply for alarm transmission
over IP. The AlphaCom XL complies with regulations: D4, M4, T5, A3, S2, I3. A higher number indicates a
better performance.
The regulations for AL1 are: T2, T2, T2, D2, M2, S1, I2.
The regulations for AL2 are: T4, T2, T3, D3, M3, S2, I3
The regulations for AL3 are: primary transmission AL2 + back-up AL1 (only AlphaCom XL!)
Most of the features of the AlphaCom PSTN2IP ML with respect to the above mentioned information are
determined by the hardware design. It is therefore not necessary to fill in specific parameters to comply. The
only point of consideration is the
Supervision Interval
(polling time) and the periodic testmessage, see
Configuration IP dialer.
It is strongly recommended when using AL1 to program the
Supervision Interval
to a value not higher than
900 (15 minutes) and for AL2 no higher than 90 seconds.
The
Periodic Testmessage
is the automatic test message generated by the AlphaCom itself. In the Standard
Settings this is not necessary. When the AlphaCom PSTN2IP ML is used in a AL2 application this value
must be programmed in the
Backup Settings
to 1440 minutes (the regulation states less than 1x per 25
hours).
