What is the PL-4 alarm response requirement?

• A. SF provides armed response to incidents/alarms; owner maintains primary security.
• B. Owner/user maintains primary security; SF provides armed response to incidents/alarms.
• C. Owner/user only monitors alarms; SF does not respond.
• D. Security is outsourced to a civilian contractor.

Answer: (B)

PL-4 alarm response focuses on who holds primary security responsibility versus who conducts armed response to alarms. The best arrangement is that the owner or user keeps primary security duties—their security policies, access control, surveillance posture, and day-to-day security decisions—while the security firm (SF) provides armed response to alarms and incidents. This setup preserves the owner’s control and accountability over security while ensuring a rapid, capable on-site reaction to triggered alarms. The other scenarios either shift the primary security responsibility away from the owner, remove the armed response element, or outsource in a way that blurs lines of command and accountability, which does not align with PL-4 requirements.
