• Semi-conductor output electrically isolated from LSN loop and short-circuit proof
• Max. switchable current per output 700 mA
• Individually selectable input monitoring functions (EOL or contact)
• Maintains LSN loop functions in the event of wire interruption or short-circuit thanks to two integrated isolators
The FLM‐420‐O1I1 Output-input Interface Modules are fitted with one output to control external devices and with one monitored input.They are 2‐wire LSN elements for connection to the fire panels FPA‐5000 and FPA‐1200 and offer the enhanced functionality of LSN improved technology.
Functions
The semi-conductor output is electrically isolated from the LSN loop and protected against short circuits.
Functionality of the semi-conductor output
Output power supply
The power supply for loads connected to the output can be selected as:
• Auxiliary power supply from the fire panel
• Or, for FLM‐420‐O1I1-D only: External power supply units
Input monitoring functions
The FLM‐420‐O1I1 Output-input-Interface Module provides two monitoring functions:
1. Monitoring of a line by an EOL resistor
2. Monitoring of a potential‐free contact The input monitoring functions can be selected by setting the corresponding addresses.
Line monitoring with EOL resistor
The EOL resistor has a standard resistance of 3.9 kΩ.
The interface module detects
• Standby
• Triggering in the event of a short circuit
• Triggering in the event of line interruption
The EOL resistor has a standard resistance of 3.9 kΩ.
The interface module detects
• Standby
• Triggering in the event of a short circuit
• Triggering in the event of line interruption
Position Description
RΣ Overall line resistance with RΣ = RL/2 + RL/2 + REOL
RL/2 Line resistance
The following line conditions will be reliably detected if the overall line resistance is within the specified range:
Line condition Overall line resistance R Σ
Standby 1500 Ω to 5500 Ω
Short circuit < 800 Ω
Interruption > 85000 Ω
Contact monitoring
The interface module evaluates the operating conditions "open" or "closed". The normal operating condition can be programmed for each input. Contact
monitoring has a pulse intensity of 8 mA.
Adress switches
The address of the interface module is set using:
• DIP switches in case of the FLM‐420‐O1I1‐E
• Rotary switches in case of the FLM‐420‐O1I1‐D
In improved version LSN mode, the operator can select automatic or manual addressing with or without auto-detection.

LSN features
Integrated isolators ensure that function is maintained in the event of a short circuit or line interruption in the LSN loop. A fault indication is sent to the fire
panel.

• Can be connected to fire panels of LSN improved bus technology.
• Programming is done with the programming software of the fire panel.
• The LSN connection is established by the two wires of the LSN line.
• The power supply for the output is either fed by the auxiliary power supply from the fire panel or by an external power supply unit. External power
supplies, for FLM‐420‐O1I1-D only, must be free-of-ground.
• The outputs OUT/OUT- are switched against the negative potential of the interface module (POWER IN/0V). The positive potential (OUT/POW+) is either supplied by the auxiliary power (AUX) from the fire panel or by an external power supply unit.
• The maximum switchable voltage of the semi-conductor output is 30 V DC. The maximum switchable current is 700 mA (depending on the external power supply).
• The activation of the input IN has to be carried out electrically isolated from LSN (e.g. with relay contacts, pushbutton, etc.).
• The input must have a minimum activation time of 3.2 s.
• For FLM‐420‐O1I1-D applies: A maximum cable length of 3 m is permitted per input and output.FLM‐420‐O1I1-E must be mounted flush with the connected device.
• 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). With UEZ 2000 LSN and UGM 2020, the limitation to 500 m applies to each Network Processing Converter (NVU).
• The interface module has terminals blocks to allow a second pair of wires to be looped through to supply the downstream connected elements with LSN power.
• For a fire system operation according to EN 54‐2,the interface modules used for the activation of fire protection equipment and whose outputs are not monitored, must be installed directly next to or within the device which shall be activated.
