8.12 Alarm delay
This avoids spurious alarm signals triggered by high water turbulence.
Set the time to the shortest period that avoids 'false' alarm signals:-
8.13 Alarm lockout
If 'No' is selected, the low alarm relay will only be de-energised
(e.g. will cause the alarm to sound), for the duration of a low water level,
and will revert to normal operation as soon as normal water level is
reached.
If 'Yes' is selected, the low alarm relay will stay de-energised until the
'Input Code' screen is accessed and the security code entered. See
Section 12.2, page 40.
