A problem using DSL Filter for a monitored alarm is typically associated with which issue?

• A. Line seizure problems
• B. Power supply failures
• C. False alarms
• D. Tampering

Answer: (A)

DSL filters separate voice and data on a single telephone line, but the alarm panel’s dialer relies on a clean, steady line and proper dial tone to seize and release the line when it sends signals. If a filter sits in the path the alarm uses to dial out, it can distort or weaken the signaling and dial tone the panel expects. That disruption makes the panel think the line is still in use or not properly connected, leading to line seizure problems. The other issues listed (power faults, false alarms, tampering) aren’t caused by the presence of a DSL filter in the alarm signaling path, so line seizure problems is the best match.
