ADSL Alarm Filter with Lightning Protection

Enables analogue alarm communication on Broadband/DSL lines!

The new ADSL Alarm Filter is designed to meet BS/EN50131 requirements enabling analogue alarm signals to operate securely on Broadband/DSL lines.

This is the only filter that allows isolation of the DSL portion of a broadband enabled line. In the event of an alarm condition, the filter continues to allow devices connected to the broadband to operate normally, whilst seizing the analogue line to make the alarm call.

The filter can be installed on existing systems in readiness for broadband when it becomes available. Customers should be warned that communication and insurance cover may be lost if a filter is not fitted to the alarm system.

To comply, the filter should be installed within the alarm control equipment and connected as follows:-

AB LINE -Incoming telephone line to premises (from Master Socket).
AB LINE OUT -DSL Line (combined analogue and digital signal) to all subsequent sockets in premises.

AB TO EQUIPMENT -Connection of line to alarm control panel communicator.

A1, B1 FROM EQUIPMENT -Output of alarm panel communicator back to line (where applicable).

PASS THROUGH 2 -Not used
