Line standby current
The standby current I
R
of the detector line must be calculated as shown
below:
I
R
Standby current of the detector line in [A]
U
L
Detector line voltage in [V]
R
E
Original termination resistor of the detector line in
[Ω]
The shown formulas for calculation of the termination resistor and the
standby current of the detector line take the ideal state of signal evaluation
into consideration. If no acknowledgement is achieved by means of the
calculated termination resistor of the reset circuit board, the value of the
termination resistor must be reduced by approx. 20%.
Termination resistor
The reset circuit board emulates the detector line termination resistor. It is
recalculated and installed on the reset circuit board (connection X1). The
value of the termination resistor
R
ER
is calculated as shown below:
R
ER
Termination resistor in the reset circuit board in
[Ω]
U
L
Detector line voltage in [V]
I
R
Standby current of the detector line in [A]
The reset circuit board can only be used when the standby current of the
detector line is between 5 mA and 50 mA and the detector line end is
formed by an Ohm resistance. The reset impulse is triggered if the line
voltage falls below 3 V when resetting the control panel.
