Your requirement I understand is that you have a timer which is on during the restart for a while, and want a control to enable or disable the sending.
For example, you create a switch called sendAlarm.
Pager.send = $Alarm.update and sendAlarm and !Timer.
Then, only when the sendAlarm switch is on, Timer is off, and there is a new alarm, the pager will send the alarm message. This alarm will be in alarm window, will be logged, but not be sent if you turn off the switch. So, when you want to test, just turn off the switch.
