NOTICE!
Remote alarm indications activated by the detector C point:
A maximum 500 m of additional cable length is allowed when using remote displays (e.g.
MPA/FAA-420-RI).
The total length of installed line must not exceed the limit of 3000 m!

Limits of SG 200 application

The cable resistance depends on the number of acoustic signaling devices.
Limits:
Maximum of 500 mA from the NZM 0002 A. Minimum voltage of 10 V at last SG 200 in loop.
