Problem-Solving and Critical Thinking Flashcards

A control panel displays a 'tamper' trouble on a specific zone. Upon inspection, all device covers appear closed. What should the technician investigate next?

Answer: Check for a loose or partially open tamper switch inside the device housing

Tamper switches can activate if the device housing is not fully seated or latched, even when it appears closed from the outside.

An alarm system was recently upgraded, but the customer reports that entry delay is not functioning on the front door. What is the most likely cause?

Answer: The front door zone was programmed as an instant zone instead of a delay zone

If the zone type was not correctly configured as an entry/exit delay zone during the upgrade, it will trigger immediately upon activation.

A monitoring center reports receiving duplicate alarm signals from the same account within seconds of each other. What could cause this?

Answer: The panel is programmed to use dual-path reporting, and both paths sent the alarm simultaneously

Dual-path or redundant communication configurations can transmit the same event over multiple channels nearly simultaneously, appearing as duplicates.

After replacing a control panel, the customer's existing keypads are not communicating with the new panel. What is the most likely issue?

Answer: The new panel uses a different communication bus protocol incompatible with the existing keypads

Different panel manufacturers and generations often use proprietary bus protocols, making existing keypads incompatible with a new panel.

A customer complains that their alarm sounds a trouble beep every night at the same time. What is the most likely cause?

Answer: The backup battery is failing and drops below threshold during AC power peak-load hours

Backup batteries often show low-voltage conditions during high-load periods, triggering a trouble tone that may occur predictably at certain times.

A technician must determine why an alarm was not transmitted to the monitoring center during an actual break-in. Which log should be reviewed first?

Answer: The keypad event log on the control panel

The control panel's event log records all system activity, including alarms, troubles, and communication attempts, making it the primary diagnostic tool.

A retail store's alarm system is tripping during business hours when employees open a specific emergency exit door. What is the correct fix?

Answer: Program an extended entry delay or use a shunt key switch on that door zone

A shunt key switch or properly programmed delay allows authorized use of the door without triggering an alarm during business hours.
