Installation:
WARNING
Electrical voltage
Before installation with output card (4M):
● Switch off the panel’s power supply.
● Disconnect power cable at the terminal '20-30V' on the output card (4M)
Detailed information on installation is available in document A6V10431015. See
chapter '
Technical:
● Max. current of each output: 1.0 A @ DC 26 V
● Max. current of total outputs: 2.0 A @ DC 26 V
● Each line must be terminated with EOL element (Resistor 2.2 kΩ/1 W/0.5 %).
● Additional technical details if option creeping open/short is activated:
– When the output is configured as 'RT Fire', 'Sounder line' or 'Fire control',
max. line resistance is 74.3
Ω; min. sounder voltage is DC 16 V.
– When the output is configured as 'RT Fault', the resistance scope is
350
Ω ~ 2500 Ω.
Configuration:

Checking the line resistance depending on the required current
It must be calculated to ensure the supply of the connected devices is met.
The picture shows the dependence of the line resistance (R Line) in relation to the
device voltage (U
min
), the available output current (I
max
) and the minimum required
current of the connected devices (I Load).

Procedure for determining the maximum available device current (I Load):
1.
Determine the line resistance R Line:
– Configuring. See '
Calibrating output card (4M) [➙ 105]
– 'Engineering' > 'Calibrate 4M card line' > 'Output' 1-n > 'Calibrate EOL'
2.
Detect the voltage U
min
as per the device datasheet.
3.
Verify if all parameters satisfy the correct operations.
