Advantages Disadvantages
* Quick. A report can be sent in a few seconds * The information sent is not detailed. No
information on which zone or user caused the
report
* Status of all channels is reported * In a system split into 8 areas, only 2 channels
are available for each area
* In a split system, 1 Account Nbr can be used
without information being lost
2. Contact ID:
Contact ID was introduced because Fast Format protocols have limitations in large systems. The Fast
Format protocol can report a maximum of 18 events (16 channels, battery low and 24 hour report).
Because alarm systems are becoming larger and larger, requirements have increased to obtain a more
accurate picture of the place where the events occur. For example, suppose there is an alarm in factory
buildings 1, 2 and 3. In Fast Format this would already take up 3 channels. If you also wanted to see which is
arming and disarming, the available 16 channels are not enough.
When designing protocols with extended alarm reports it is naturally very important to maintain as high a
speed as possible. Because Fast Format is a fast protocol, it is easy to take this protocol as a basis.
Thus Contact ID uses the same construction as Fast Format. However, the reported information is changed.
The composition is now:
KKKK 18 S OOO GG NNN
KKKK is the four-figure Account Nbr.
18 is an identification for Contact ID.
S indicates the type of event which follows:
