Selection of alarm
sequence type
Selections for the
serial communication
port
34
The selectable alarm sequences are illustrated on
page 9. To select the chosen alarm sequence the
parameter selector push-button ↓ is repeatedly
pressed until the LED marked MODULE starts
glowing. Using the cursor control push-button
→, the cursor is moved to the third digit, seen
from the left, which indicates the selectable
alarm sequence types as follows:
0 = ISA A, automatic reset
1 = ISA A-1, automatic reset
2 = ISA M-1, manual reset
3 = ISA R-1, indication on return to normal
4 = DIN 19235, indication on return to normal
When the annunciator system is composed of
several interconnected units, the flash sequence
of the visual indicators can be synchronized.
One of the annunciator units is defined as the
master (1), thus delivering a synchronizing pulse
to all the other interconnected annunciators (0).
If the annunciator units are connected to a
higher level system, the synchronizing pulses for
the annunciator units are obtained automatically.
The parameter selector push-button ↓ is
repeatedly pressed until the LED marked
MODULE starts glowing. The cursor is then
moved to the fourth digit from the left of the
display with the cursor control push-button →.
The fourth digit corresponds to one of the
following functions:
0 = sync-pulse receiver, when not connected to
a higher level system
1 = sync-pulse transmitter, when not connected
to a higher level system
2 = 9600 bits/s serial communication
3 = 4800 bits/s
4 = 2400 bits/s
5 = 1200 bits/s
6 = 300 bits/s
All sequence types but ISA A requires a separate
reset of the audible alarm. The chosen sequence
is selected with the data value selector push-
button ↑ and stored in the parameter memory
with the enter command push-button.
The data value selector push-button ↑ is
repeatedly pressed until the function aimed at is
reached. The selected function is then stored in
the parameter memory by pressing the enter
command push-button.
If the annunciator unit is connected to a higher
level system by means of a serial communication
link or if the annunciator unit has been program-
med to receive an externally generated synchro-
nizing pulse and no synchronizing pulse is
received within a time period of one minute, a
visual indication in the form of a blinking deci-
mal point will be switched on in the right- hand
lower corner of the display. When no serial
communication link is connected to the annun-
ciator unit, the annunciator unit must be
programmed to function in the sync-pulse re-
ceiver mode.
NOTE!
The parameters need not to be stored in the
parameter memory one by one, but they can be
stored all together at the same time, when they
have been given their specified values in the
display.
A summary of the programming parameters
(figure 32) and empty parameter tables (figure
33 and 34) is given on the following pages.
