Qolsys IQ Panel 2 4 and 5 - Find Which Sensor Caused an Alarm

If your Qolsys system went into alarm and you are not sure what caused it, the panel and Alarm.com event history can help identify the sensor involved.

These instructions apply generally to:

  • Qolsys IQ Panel 2
  • Qolsys IQ Panel 2 Plus
  • Qolsys IQ Panel 4
  • Qolsys IQ Panel 5

Identifying the exact sensor is especially important when troubleshooting repeated or unexplained alarms.

If There May Be an Actual Emergency

Before checking alarm history, make sure there is no actual emergency.

If there may be a:

  • Break-in
  • Fire
  • Carbon monoxide condition
  • Medical emergency
  • Panic alarm
  • Other immediate danger

move to a safe location and contact emergency services as appropriate.

Do not remain inside an unsafe property to troubleshoot the alarm system.

Check the Qolsys Panel

If it is safe to do so, look at the Qolsys panel.

The panel may display information about the alarm that just occurred.

Look for a sensor or zone name such as:

  • Front Door
  • Back Door
  • Kitchen Window
  • Living Room Motion
  • Basement Motion
  • Glass Break
  • Smoke Detector
  • Carbon Monoxide Detector

Write down the exact sensor name displayed.

Check the Panel Message Center or Event Information

Depending on the Qolsys model and system configuration, recent alerts or system information may be available from the panel.

Look for information showing:

  • Alarm type
  • Sensor name
  • Date
  • Time
  • Trouble conditions associated with the sensor

Menu appearance can vary between IQ Panel models and software versions.

If you cannot locate the information, check Alarm.com instead.

Check Alarm.com Event History

Open Alarm.com and review the activity or event history around the time the alarm occurred.

Look for events immediately before and during the alarm.

You may see entries showing:

  • Alarm
  • Sensor activity
  • Arm
  • Disarm
  • Door activity
  • Motion activity
  • Trouble condition
  • System communication events

The sensor associated with the alarm is the most important information to record.

Look at Events Immediately Before the Alarm

The events leading up to an alarm can provide useful information.

For example, you might see:

System Armed Away
followed by
Front Door Closed
followed by
Living Room Motion Alarm

That sequence may help determine what happened.

Do not assume the cause based only on the last sensor you remember using. Check the recorded history.

Record the Armed Mode

Determine whether the system was:

  • Armed Stay
  • Armed Away

This can be important when diagnosing motion detector or entry-door alarms.

Record the Time

Write down the approximate time the alarm occurred.

If possible, record both:

  • Time shown in Alarm.com
  • Approximate actual time of the event

This is especially useful if the alarm happened while nobody was at the property.

Door or Window Caused the Alarm

If a door or window sensor caused the alarm, check the opening after determining it is safe.

Look for:

  • Door or window not completely closed
  • Loose sensor
  • Loose or missing magnet
  • Sensor or magnet that shifted
  • Door movement
  • Window movement
  • Physical damage

Watch the sensor status on the Qolsys panel while opening and closing the affected opening.

Motion Detector Caused the Alarm

If a motion detector caused the alarm, consider:

  • Whether anyone was inside
  • Whether pets were inside
  • Whether someone returned after arming
  • Whether furniture or room conditions recently changed
  • Whether the same detector has caused previous alarms

Do not intentionally trigger additional alarms to test the motion detector.

Glass Break Detector Caused the Alarm

First verify there is no actual broken glass or security event.

If there is no apparent security event, record:

  • Detector name
  • Alarm time
  • Any loud noises around that time
  • Whether the alarm has happened before

Do not attempt to test a glass break detector by breaking glass or producing random loud sounds.

Smoke Detector Caused the Alarm

Treat a smoke or fire alarm seriously.

If there may be an actual fire:

  1. Leave the property.
  2. Move to a safe location.
  3. Contact emergency services.

Do not remain inside to troubleshoot the detector during a possible fire.

Carbon Monoxide Detector Caused the Alarm

Treat a carbon monoxide alarm as a potential life-safety emergency.

Move to fresh air or another safe location and contact emergency services as appropriate.

Do not remain inside trying to determine whether the detector is correct.

Same Sensor Has Caused More Than One Alarm

If the same sensor appears repeatedly in alarm history, record several events if available.

For each occurrence, note:

  • Date
  • Time
  • Sensor name
  • Armed mode
  • Whether anyone was present
  • Whether pets were present
  • Weather or environmental conditions
  • Any Low Battery, Tamper, or Malfunction messages

Repeated alarms from the same sensor should be investigated by CommTech Systems.

Different Sensors Are Causing Alarms

If unrelated sensors begin causing unexpected alarms, check the panel for other system conditions.

Look for:

  • Low Battery
  • AC Power Failure
  • Communication trouble
  • Tamper
  • Malfunction

Provide CommTech Systems with the names of all affected sensors.

Alarm Happened Immediately After Arming

If the alarm occurred shortly after arming, record:

  • Whether you selected Stay or Away
  • Which sensor caused the alarm
  • Whether everyone had left the property
  • Whether pets remained inside
  • Whether the exit door completely closed

This information can help determine whether the event involved an exit door, motion detector, or another sensor.

Alarm Happened While Nobody Was There

If the alarm occurred while the property was unoccupied, review Alarm.com history around the event.

Do not enter the property if there is reason to believe a break-in or other dangerous condition may have occurred.

Contact emergency services when appropriate.

Alarm History Shows Low Battery Before the Alarm

If the affected sensor had previously reported Low Battery, record that information.

A sensor with an unresolved battery condition should be checked.

Use the correct replacement battery for the specific sensor model.

Contact CommTech Systems if the sensor continues causing trouble afterward.

Alarm History Shows Tamper

If the sensor had a Tamper condition, check whether its cover is securely installed and whether the device has been moved or damaged.

Contact CommTech Systems if the tamper remains or the sensor continues causing alarms.

Alarm History Shows Malfunction

If the affected sensor also reports Malfunction or Not Responding, contact CommTech Systems.

The sensor may not be communicating reliably.

Alarm.com Does Not Show the Event

If an alarm occurred at the Qolsys panel but the event does not appear in Alarm.com history, check whether the system has communication trouble.

Contact CommTech Systems if panel events are not reporting to Alarm.com.

Alarm.com Time Appears Incorrect

If the event is present but the timestamp appears wrong, record:

  • Time Alarm.com shows
  • Approximate actual time
  • Whether the Qolsys panel clock is correct

This information can help troubleshoot the time discrepancy.

Monitoring Center Contacted You

If the monitoring center contacted you about the alarm, follow their instructions.

Disarming the Qolsys system does not necessarily cancel an alarm signal that has already been transmitted.

Take a Screenshot

If possible, take a screenshot of the relevant Alarm.com event history.

A screenshot showing the sensor name, event type, date, and time can be useful when requesting service.

Do not include private passwords or alarm codes in the screenshot.

Do Not Delete the Sensor

Do not delete a sensor because it appears in alarm history.

Deleting the sensor can remove intended protection from the property.

Do Not Repeatedly Trigger the Sensor

Do not intentionally create additional alarm events simply to see whether the sensor appears in history.

This can generate additional monitoring signals or emergency response.

Do Not Factory Reset the Panel

Do not factory reset the Qolsys panel to clear alarm history or troubleshoot an unexplained alarm.

The recorded event information may be useful for diagnosing the problem.
