Cabling between the control unit and accessories essential to the operation of the electronic premises security system shall be monitored for integrity with a fault indicated within how many seconds?

• A. 100 seconds
• B. 300 seconds
• C. 200 seconds
• D. 400 seconds

Answer: (C)

Essential circuits that connect the control unit to essential accessories are actively watched for any loss of signal or integrity. The system is designed so that if a fault occurs in that wiring, it will be indicated within three minutes and twenty seconds. This window keeps reliability high: it’s long enough to avoid nuisance alarms from brief disturbances, but short enough to ensure a real wiring problem is detected promptly so security personnel can respond and repairs can be made. Choosing a much shorter interval could cause false fault indications from minor glitches, while a much longer interval would let a real wiring fault go unnoticed for too long, potentially compromising the system’s ability to function when needed.
