What is the effect of the cross zoning attribute on a zone?

• A. It triggers immediate alarm on any violation.
• B. It disarms the system when violated.
• C. It delays alarm transmission until another zone is violated before the timer expires.
• D. It turns off the cross zoning feature.

Answer: (C)

Cross zoning requires a second zone to be violated within the set time window before an alarm is transmitted. This means an initial breach doesn’t immediately trigger an alert; the system waits to see if another zone is also breached, verifying the intrusion. This approach reduces false alarms by ensuring two separate points are breached rather than a single sensor tripping. So the effect is that alarm transmission is delayed until another zone is violated before the timer expires, which matches the described behavior. The other options don’t fit because cross zoning isn’t about immediate alarm on any violation, disarming on violation, or turning off the feature.
