Designed specifically for homes with alarm systems, the Z-A431EU alarm filter keeps DSL service, home phoneline networking (HPN) and alarm systems functioning as they should. The alarm filter blocks DSL and HPN signals from interfering with the alarm system’s voice-band modem. At the same time, it isolates DSL and HPN equipment from alarm equipment impedances. With this two-way protection, the alarm filter keeps the alarm system operating reliably around the clock and ensures fast, uninterrupted DSL and HPN access even while the alarm system is dialing.
Installation is simple for the service technician – just connect the phone line and alarm panel connections to the screw terminals. The alarm filter’s premium performance and reliability means fewer service calls for providers, more satisfied customers, and cost savings for everyone.
