typical value for Carrier Delay is 10, meaning 1.0 seconds. The 8310 will key the transmitter,
wait for the carrier delay period and then send data. The Carrier Delay affects both internal and
external transmitters.
SSP Settings/ReplyDelay
Reply Delay sets the Time that the 8310 will delay before it replies to a message. Its default
value is 0, meaning no delay. A value of 10 would cause the 8310 to wait 1 second after
receiving a message before transmitting the reply. ReplyDelay is useful, if the system sending a
request, needs a second or two to get ready for the reply.
SSP Settings ACKDelay
Ack Delay sets the Time that the 8310 will wait for an acknowledgment when sending an SSP
message. Many SSP messages expect an acknowledgment from the receiving end to let the
sender know the message was received without errors. With Ack Delay 100 (the default value),
the Ack message must be received in 10 seconds. On radio systems with multiple repeater
paths, Ack Delay should be much longer (about 10 seconds for each path).
This value is shared by both radio and telephone communications. If you are using both modes,
set the value to the longer of the two response times.
SSP Settings NumRetries
See RetryIn (above) for a description of how NumRetries is used to control the number of re
transmissions that are made when a sensor goes into alarm. If NumRetries is set to 0, no re
transmissions are made. A typical value for NumRetries is 3.
SSP Settings RetryDelay
When a sensor goes into alarm, the 8310 will immediately make a transmission. If the ACK is
received, the 8310 changes the sensor status to Alarm and will not attempt a retry. If no ACK is
received and NumRetries is >0, the 8310 will delay based on RetryDelay and then try again. This
continues until the number of attempts > NumRetries.
The 8310 delay is actually a random delay based on RetryDelay. With RetryDelay set to
00:01:00, the delay will be anywhere from 0 and 60 seconds (00:01:00). Typically, RetryDelay is
a short Time of less than 10 minutes or so.
Station Setup/Communications/COMx ALERT
This menu provides access to all ALERT settings needed to configure the ALERT modem for
transmissions. A typical ALERT Settings menu is shown below followed by a description of all the fields.
ALERT COMx:
Enabled No
TxTime 00:00:00
BaudRate 1200
Select outputs ►
End ALERT Menu
Enabled
This property must be set to YES to enable ALERT transmissions.
TxTime
This property defines an offset to timed transmissions. When 00:00:00, no offset is applied.
Hence, given a timed transmission with interval 01:00:00, if TxTime were 00:15:00, then the
