3. FB3 detectors cannot be turned on. L1458B cannot be turned on.
Mainframe monitor (telnet tsir 3015) says in upper left-hand
corner:
Bad 24V, Thermal Overload?
0.0 Ds
Will need IR access to figure out what's wrong/fix.
Hasta la vista! Feliz Navidad! (I don't know how to say
"Happy New Year" in Spanish.)
