10.3.9 Alarm delay:
dELA
This function enables activation of the alarm output
to be delayed for a fixed time following the alarm
condition occurring. The delay can be set in 1
second increments up to 3600 seconds. If a delay is
not required zero should be entered.

an alarm condition occurs and will continue for the

activated and the alarm annunciator will be
permanently activated.
10.3.10 Alarm silence time:
5IL
The alarm silence function is primarily intended for
use in small installations where the alarm output
directly operates an annunciator such as a sounder.
When the alarm silence time is set to any figure
other than zero, the BA588E Rate Totaliser
(
push
button becomes an alarm accept button.
After an alarm has occurred, operating the
(

non-alarm condition for the configured alarm silence
time. When an alarm is silenced the alarm
annunciator will flash until the silence time expires.

&
or

alarm silence time in seconds with one digit flashing.

10.3.11 Flash display when alarm occurs:
FL5H
In addition to the two alarm annunciators on the
lower left hand side of the Rate Totaliser display
which show the status of both alarms irrespective of
which input is being displayed, this function provides
an even more conspicuous indication that an alarm
condition has occurred.
When enabled and the Rate Totaliser is displaying
the input on which the alarm has occurred, the
fla5h
function alternates the rate or total display
between the numerical value and the alarm
identification. For example if alarm 1 has been
activated by a rate alarm occurring on input A the
rate display will alternate between the numerical rate
value and
AL1
, plus the input identification
in - A
if
5td
has been selected for the lower display
configuration
di5P-2
See 5.11.
Note: When an alarm occurs on one input the flash
function will only be seen when viewing that
input, not when the Rate Totaliser is showing
the other input or the composite display.
However, the two alarm annunciators, which
indicate the status of each alarm, are
activated irrespective of which input is being
displayed.
To enable the function select
FL5H
from the alarm
sub-menu using the
&
or
*
push button and press
(
to check or change the function. The
&
or
*

and
on
, when set as required, press the
)
button to
return to the
FL5H
prompt in the alarm sub-menu.
10.3.12 Access Setpoints:

provides direct access to the alarm setpoints from
the totalising mode by simultaneously operating the
(
and
*
buttons. An operator can therefore
adjust the alarm setpoints without having access to
the configuration and alarm sub-menus. Protection
against unauthorised or accidental adjustment is
provided by a separate optional security access
code.
Using the
&
or
*

AC5P
