ACT 2468

RFI Filter for Alarm Circuit Cables

The ACT 2468 RFI Filter is designed to attenuate RFI signals picked up by
alarm cables acting as aerials. It snaps apart to make any combination
of 2, 4, 6 or 8 wire RFI filters which can be fitted to either or both ends of
the alarm circuit cable.
The powerful 1Amp rated RFI filter can be used to attenuate radio
frequency interference on any alarm circuit, DC supply or sounder and
are also compatible with most analogue/digital data cables. The RFI filter
offers virtually no resistance to conventional DC circuits but substantially
attenuates RFI signals between 2.5MHz and 800MHz, making them more
cost effective and quicker to install than screened cable.
Connections
Troublesome alarm circuit cables should be connected to the INPUT side
of the filter with the OUTPUT side connected to the alarm equipment (i.e.
Panel, Keypad, LIM, Expander, Detector etc).
