ANNEX. CURRENT CONSUMPTION ESTIMATION
Table 13 shows the standard values of current consumed by the Signal-10 in main operation modes
in case of standard operating.
Table 13. Standard Current Consumption Values
Device Conditions
Mode
Power Voltage
12 V
24 V
All alarm loops of the Signal-10 are armed and
there are no detectors powered via alarm
loops
Operation
220 mA
110 mA
Alarm
230 mA
115 mA
All alarm loops of the Signal-10 are armed, all
detectors are powered via alarm loops, and
total current consumption in each alarm loop is
3 mA (totally, I = 30 mA)
Operation
310 mA
150 mA
Fire Alarm
(two detector
has actuated)
410 mA
200 mA
If alarm loops of the device are loaded partially (that is, some detectors are powered via the loop but
its totally consumed current doesn’t exceed the maximum value) then the current consumed by the
Signal-10 can be considered to increase in direct proportion to the current consumed by the detec-
tors.
In such a way, if all termination resistors are installed, the current consumed by the Signal-10 can be
calculated by formulas:
In case of device being powered from a 12 V power supply:
I = 2.75
××××
i + 220 [m
А
]
In case of device being powered from a 24 V power supply:
I = 1.23
××××
i + 110 [m
А
]
Where: I is the total device consumed current (without regard to external annunciators) [m
А
],
i is the current consumed by active detectors from alarm loops [m
А
].
The total time of battery-backed device operation, taking into account the margin 25%, is calculated
by formula:
T = 250
××××
W / I [
ч
]
Where: W is the capacity of a backup battery [
А
h],
I is the current consumed by the device [m
А
].
