Section 5: 7845CZ Installation
5–5
Auto Roam: This mode is used in mobile installations
where the 7845CZ tests both sides and chooses the best of
both sides. If the radio loses coverage, it cycles through the
list of carriers stored in EEPROM. When the list is
exhausted, the radio actively tests for service whether or
not it is registered.
A Only: This mode is used in fixed installations where the
7845CZ tests only the A side and chooses the best if more
than one carrier was found. If the radio loses coverage, it
cycles through the list of carriers stored in EEPROM.
When the list is exhausted, the radio actively tests for
service if it is NOT registered. If it is registered, it goes
back to the top of the list and tries again.
B Only: This mode is used in fixed installations where the
7845CZ tests only the B side and chooses the best if more
than one carrier was found. If the radio loses coverage, it
cycles through the list of carriers stored in EEPROM.
When the list is exhausted, the radio actively tests for
service if it is NOT registered. If it is registered, it goes
back to the top of the list and tries again.
Question 7.
Flt Time (min)
Enter in minutes 1 - 99 the time delay before the 7845CZ
notifies the control panel that there is loss of contact with
the network. The 7845CZ will alert the control panel of
the loss of contact with the network by changing the state
of the fault output.
