Safety
NOTICE!
i
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
The FLM-420-O1I1-E Output Input Interface Module has one semiconductor output (OC) for controlling external
devices and one monitored input.
The output is electrically isolated from the LSN loop and protected against short circuits.
Connected loads can be power-supplied in two ways:
– by the auxiliary power supply from the fire panel, or
– by an external power supply unit.
For the input, two monitoring functions can be selected (see Figure 4, Page 3):
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
The programming is carried out via the programming software of the fire panel.
The FLM-420-O1I1-E can be flush mounted in standard device boxes in accordance with EN 60670 (see Figure 7,
Page 7), for example, in standard switching programs (see Figure 8, Page 7); alternatively, it can be installed in the
devices (see Figure 9, Page 7).
NOTICE!
i
The FLM-420-O1I1-E Output Input Interface Module is connectable with Panel Controller
firmware version 1.3.10 and above.
Address Setting
Address setting is carried out using the 8 DIP switches and a suitable pointed object (see Figure 1 to Figure 3, and
the following tables).
It is not permitted to use different operating modes in the same loop, stub or T-tap next to each other!
Address (A) Operating mode
0 Loop/stub in LSN improved version mode with automatic addressing
1 ... 254 Loop/stub/T-taps in LSN improved version mode with manual addressing
255 = CL Loop/stub in LSN classic mode (address range: max. 127)
Wiring
The output OUT/OUT- is switched against the negative potential of the interface module (POWER IN/POW-).
The positive potential for OUT/POW+ is provided either by the auxiliary power supply (AUX) from the fire panel (see
Figure 5, Page 6) or by an external power supply unit (see Figure 6, Page 6).
OUT/POW+ and POWER IN/POW+ are linked internally.
The external power supply unit must be free-of-ground.
NOTICE!
i
A maximum cable length of 3 m is permitted per input and output.
The maximum cable length of all inputs connected to the loop or stub is 500 m in total.
Additionally, all outputs which are not electrically isolated from LSN must be included in the
total line length calculation (e.g. peripherals connected via C points).
