Hello,

that is actually the network delay. The alert is queued for processing. As gateway has only one modem, it can do only one SMS at a time. So alert queue sees incoming:
Alert: ZP, Flags: 1, Text: Zone 1 PIR Ground alarm      <--- Approx 20:37 hrs
SMS begin: 1
SMS end: 1

I one successful SMS. I guess you have 3 numbers defined to receive the SMS? Since for same alert there is:
SMS begin: 1
SMS end: -11
And then again:
SMS begin: 1
SMS end: -11

Only then the new alert is processed, again to three numbers.
Alert: ZP, Flags: 1, Text: Zone 2 Smash Slide Gnd alarm <--- Approx 20:41 hrs
SMS begin: 1
SMS end: 1
SMS begin: 1
SMS end: -11
SMS begin: 1
SMS end: -11

The "SMS end: -11 " is actually timeout reached, waiting for network ACK.

Modem is waiting for network ACK of SMS being sent. This does not mean that the SMS is not sent, only that modem did not get the network ACK.

Do you really have 3 users defined as recipients?
