graphic display of alarm types.
n-on – normal (transition from 0 to 1),
n-oFF – normal (transition from 1 to 0),
on - switched on,
oFF – switched off,
H-on – manually switched on; till the
time of alarm type change, the alarm
output remains switched on for good.
H-oFF – Manually switched off; till the
time of alarm type change, the alarm
output remains switched off for good.
