NOTICE! Installation must only be performed by authorized and specialized personnel!
WARNING! Live components and stripped cable! Risk of injury from electric shock. The
!
system must be current-free during connection work.
CAUTION! Electrostatic discharge (ESD)! Electronic components could become damaged.
Ground yourself using a wrist strap or take other suitable actions.
Functional description
FLM-420-I2 Input interface modules provide three monitoring functions:
1. Monitoring a line with EOL resistor for standby or triggering (interruption/short circuit)
2. Monitoring a potential free contact for "open" and "closed" states
3. Voltage monitoring between 0 and 30 V DC.
The FLM-420-I2-D is installed on a DIN rail in accordance with EN 500022 with enclosed adapter (see Figure 1,
page 3; Removal, see Figure 2, page 4).
Address setting
Fit a rotary switch in the required position using a pan head slotted screwdriver (see Figure 3, page 5).
It is not permitted to use different operating modes in the same loop/stub/T branch next to each other!
Address (A) Operating mode
0 0 0 Loop/stub in LSN improved version mode with automatic addressing
0 0 1 ... 2 5 4 Loop/stub/T branches in LSN improved version mode with manual addressing
CL 0 0 Loop/stub in LSN classic mode (address range: max. 127)
2 5 5 ... 2 9 9 Non-permitted address range (error message on fire panel)!
Connection (see Figure 4, page 6)
