Hello,
You can have the AlarmNotifier sending the SMS whenever an alarm is assert.
How to configuring Spectrum Alarm Notifier to send - CA Knowledge
Different Alarm Scripts in Spectrum
You can use the SANM (Spectrum Alarm Notification Manager) to start and end sending the SMS in a daily basis.
There is no ability to define an end to the schedule, as the assumption is made that a different schedule will be in place if/when the current one needs to change.
The Start of the new one would bring the end of the current.
Basically schedule the policy to associate to the default policy at a certain time, then have the default policy do nothing.
