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
The FLM-420-I8R1-S Octo-input Interface Module provides two monitoring functions (see Section 5. , page 5):
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 monitoring functions of the eight inputs can be selected individually by setting the corresponding addresses.
Additionally, the FLM-420-I8R1-S has a change-over contact relay to provide a potential free output contact.
The programming is carried out via the programming software of the fire panel.
Cables are fed through rubber bushings or PG cable glands (see Section 3. , page 4).
The pluggable terminal blocks of the interface module allow for an easy wiring (even if built in).
Address setting
Fit a rotary switch in the required position using a pan head slotted screwdriver (see Section 4. , page 5).
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 0 0 Loop/stub in LSN improved version mode with automatic addressing
0 0 1 ... 2 5 4 Loop/stub/T-taps 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 Section 6. , page 6)

NOTICE!
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
i
total line length calculation (e.g. peripherals connected via C points).
The activation of the inputs IN 1...8 has to be carried out electrically isolated from LSN (e. g.
with relay contact, pushbutton, etc.).
The inputs must have a minimum activation time of 3.2 s.
