Locksmith Security Systems 3

Question 1

What does a 'supervised' wireless alarm sensor mean?

Accepted Answer

It periodically transmits a check-in signal to confirm it is functional

Answer

Supervised wireless sensors send periodic heartbeat signals so the panel can detect if a sensor stops communicating.

Question 2

Which alarm panel zone type is used for smoke detectors and remains active even when the system is disarmed?

Accepted Answer

24-hour zone

Answer

A 24-hour zone is always active regardless of arm status, commonly used for life-safety devices like smoke detectors.

Question 3

What is the primary purpose of a duress code in an alarm system?

Accepted Answer

To silently alert the monitoring center while appearing to disarm normally

Answer

A duress code disarms the panel normally in appearance but sends a silent distress signal to the monitoring station.

Question 4

What battery backup duration is typically required by UL standards for residential alarm panels?

Accepted Answer

24 hours

Answer

UL 681 and related standards generally require 24 hours of standby power followed by sufficient alarm time for residential systems.

Question 5

Which communication path is least vulnerable to being cut by an intruder before a break-in?

Accepted Answer

Cellular radio communicator

Answer

Cellular communicators use wireless networks, so cutting the phone line at the premises does not disable communication.
