Signal-10 Programming

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 kΩ 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 kΩ by using the formula:

281

−=

ADC

R , [kohm],

where R

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 kΩ to 50 kΩ.

You can also read ADC values by means of S000М/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
