Betsy, Dave:

I have written a python programme which permits observatory staff to sign up to be notified when H1 loses lock. It has an EPICS interface, and is controlled and monitored by a MEDM screen (see attachment).

The MEDM is launched from the SITEMAP under the OPS button.

When H1 loses lock, a counter is started. If the counter exceeds the alert time (currently 2 minutes), alerts are sent to any selected clients. An email is always sent, and optionally a cell phone text message can also be sent if that option is turned on.

The system can be completely disabled with the master enable button.

The alerts will not be sent outside of the time window defined by the START and END settings (currently alarms sent between 8am and 11pm).

If you would like to be added to this system, please contact me.

From the attachment you can see I have tested it with Robert this afternoon.
