ACT 431 ADSL Filter with Lightning Suppression
ACT 431 ADSL Filter with Lightning Suppression is designed for alarm systems that use analogue signalling on Broadband/DSL telephone lines. It meets BS/EN50131 requirements and allows analogue alarm signals to operate securely while Broadband/DSL services are present. Built-in lightning surge and power cross protection also helps protect connected customer premises equipment.
The filter provides terminal connections for direct wiring between the master telephone socket and the alarm equipment. It is suitable for use with Redcare, digital communicators and speech diallers. When correctly connected to the master socket, the arrangement can also provide line seizure for compatible alarm equipment.
ACT 431 ADSL Filter with Lightning Suppression includes dedicated terminals for the incoming BT line, the master socket Phone/Fax line, the alarm equipment AB line and A1/B1 connections from suitable equipment. Pass-through terminals are also provided for connections that simply need to pass through the unit. Where A1 and B1 connections cannot be made, the filter can still be connected to the BT line and alarm equipment AB line, although analogue line seizure will not be provided.
