Figure 13. Programming Statuses and Transition Thresholds for Alarm Loops of the Type 12
Each status is to be selected from a drop-down list (see Figure 13.), the transition thresholds between
them being programmed in ADC units ranged from 0 to 255. As far as an ACD value is typed or se-
lected by narrow buttons, an approximate loop resistance value in k
Ω
is appeared at the next field at
the right.
Practically, it is too difficult to know which loop resistance value can match to a particular loop status.
Thus, the UProg facilitates this task by the special actual resistance measuring tool. To measure the
resistance of an alarm loop connected to the Signal-10 along with included devices being in a particu-
lar condition, press the Read button located in the ADC Reading field. The value measured in ADC
units can be converted to a value expressed in k
Ω
by using the formula:
1
281
lp
− =
ADC
R , [kohm],
where R
lp
is the alarm loop resistance value;
ADC is the ADC value measured by the Signal-10
The formula provides adequate calculating of actual resistance values ranged from 0.1 k
Ω
to 50 k
Ω
.
You can also read ADC values by means of S000
М
/S2000 console tools.
While programming a loop of the Type 14, Fire Threshold Addressable alarm loop, the Related Ad-
dressable Detectors pane (see Figure 14) is output at the display in order to match own addresses of
