3 Set the Loop Verification Interval. This deter-

mines how often a test signal is sent through the

communication loop verifying the loop’s integ-

rity. The loop’s data bandwidth will be reduced if

the test interval is shortened or the loop’s data

bandwidth can be increased if the test interval is

lengthened. The test signal is a relatively short

signal, and using the default value of 60 seconds

is an optimum setting. If the test signal is not

received within the defined time interval a Loop

Trouble alarm is generated.

4 Select either (or both) buffer check boxes

[Buffer all panels on exit and Unbuffer all

panels on startup] to apply buffering instruc-

tions.

Select Buffer on Exit to automatically buffer all

panels when the communication server is

stopped. Select Unbuffer on Startup to auto-

matically unbuffer all panels when the communi-

cation server is started.

NOTE: Logging in or out of the database server

doesn’t affect the communincation server. The

communication server runs until it is shut down (either

manually or by shutting down the operating system).

5 Indicate the Time Zone in which the loop is

located.

6 Set the Panel Defaults:

I/O Poll Interval: [defaults to 60 seconds] Sets

the frequency for the signal sent to the panel to

verify communication and to check the panel’s

input and output states.

The loop’s data bandwidth will be reduced if the

test interval is shortened or the loop’s data

bandwidth can be increased if the test interval is

lengthened.
