ACT Meters 2468 RFI Filter for Alarm Circuit Cables

Keep security and fire alarm systems reliable with the ACT Meters 2468 RFI Filter. This inline RFI filter stops radio-frequency interference from causing false alarms, corrupting keypad or LIM data, and degrading performance of detectors, sounders and DC access control devices. The 1A-rated unit supports both 12V and 24V DC normally-closed, end-of-line and fire alarm circuits while offering virtually no resistance to DC signaling, preserving response speed. Engineered to attenuate interference across a wide band (approximately 2.5Hz–800MHz), the ACT Meters 2468 delivers effective EMI suppression for surveillance, monitoring and access control networks without costly re-cabling. The supplied snap-apart 1×8 block can be split into 2×4 or 4×2 modules on-site for quick, flexible installation between alarm wiring and control equipment. Ideal for installers, integrators and service teams, this RFI filter reduces nuisance alerts, improves uptime and lowers maintenance costs across security and fire alarm applications. Add the ACT2468 to your next project to streamline troubleshooting and enhance system reliability — order now or contact our sales team for bulk pricing and technical support.
