Shiela, Jenne, TJ, Dave:

Following discussion with Sheila, Jenne and TJ it was decided that the LLA system should send alerts when there is a squeezer oscillation requiring operator intervention. Previously, alerts were not sent when the IFO was in its target state of locked and observe.

The system now sends guardian alerts independent upon the IFO state. Alerts are latched once they are sent, preventing repeat alerts. When the guardian IFO_NOTIFY goes out of alert the latch is unset. The contacts' status are no longer cleared continually, instead they are only cleared when the IFO state changes.
