4.3.2 Medium Security Application

Polling times are typically 1 to 4 hours. Path integrity is important, and short interruptions in

network service might be indicated at the premise and central station. The following Medium

Security Application recommendation assumes the ITS-DX4020-G is the primary

communication device with no backup.

Control Panel Settings

– Poll Rate: 3 hours

– ACK Wait: 300 sec (5 min)

– Retry Count: 5

ITS-DX4020-G Settings

– GPRS ACK Timeout: ACK wait (300 sec) x 2 = 600 sec

By setting the GPRS ACK timeout less than the retry count, the ITS-DX4020-G can

reconnect to the network if the carrier dropped the connection or for short maintenance

interruption outages.

– GPRS Session Timeout: Must be greater than control panel poll time (3 hours) + ACK

wait (5 min) x Retry Count (5) + ACK Wait (5 min) = 3 hours and 30 min. The GPRS

session timeout default setting of 4 hours is acceptable.

D6x00 Receiver Settings

– Control Panel Poll Rate: 4 hours

– ACK Wait: 15 sec

NOTICE!

If you use a control panel poll rate of 4 hours, change the default GPRS session timeout to

5 hours. Ensure that your SIM service provider’s session timeout is greater than 5 hours.

Check the information that came with the SIM card. If the carrier’s session timeout is less

than your GPRS session timeout, the communication path is dropped by the carrier and the

event message is not received until a new connection is made, delaying your event messages

from being delivered when expected. To ensure the communication path is not dropped, set

the poll rate to less than the carrier timeout (for example, 2 hours).

NOTICE!

To set the control panel poll rate by the hour, ensure that the D6x00 Receiver has D6200CD

V1.35 firmware or later.

Because the Bosch D6x00 Receivers only have hours and seconds settings, the receiver would

have to be set to 4 hours instead of 3 hours and 30 min. The receiver can only support up to

255 sec maximum for the ACK wait time.
