Configuration/settings/hide alarm
From DAViCal Wiki
$c->hide_alarm = true;
default: false
If true, then VALARM from someone other than the admin or owner of a calendar will not be included in the response.
Often these alarms are only relevant to the owner, but in some shared calendar situations they might not be in which case you might wish to leave this set this to false. The default is false because the preferred behaviour is to enable/disable the alarms in your CalDAV client software.
Available from DAViCal version: 0.6 or so and later
