2 Functional description
The FLM-420-O1I1-E can be flush mounted in standard device boxes in accordance with EN
60670, for example, in standard switches. Alternatively, it can be installed in the devices (see
Graphics).
The Interface Module has one semiconductor output 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 by the auxiliary power supply from the fire panel.
For the input, two monitoring functions can be selected (see Graphics):
1.
2.
The programming is carried out via the programming software of the fire panel.
3 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 by the auxiliary power supply (AUX) from the
fire panel.
OUT/POW+ and POWER IN/POW+ are linked internally.
