Note
The use of Model 6 and Model 26 equipment for data
transmission with a trunked radio system raises a number of
technical issues that are typically not encountered with wire line
or conventional radio equipment. In general, trunked radio
systems introduce longer delays on the initial transmission of an
alert than a conventional radio. Additionally, the type, mode, and
configuration of the trunked system can significantly impact
overall fire alerting system performance, particularly with respect
to multi-station alerting speed. If you are considering a Model
6/26 installation in which FFSK data is to be transmitted over a
trunked radio channel, please contact Zetron Product Support as
early in the planning cycle as possible.
Poll Time
Note
The parameters Poll Time and Stations per Poll Time appear
in all communications modes except for Wire line. In the Wire
line mode, the Poll Time is fixed at approximately once per
second.
Before going further it may be helpful to define a few terms to avoid confusion.
• Polling Time = the period between polling cycles
• Polling Cycle = the process of polling a fixed number of Model 6 units
or the time needed for this process to take place
