Doorbell
Someone rings the entrance bell.
Check who is waiting and who should respond.
Signal library
What starts the work?
A ring, a reading, a request. Use these examples to picture the signals in your operation and the questions they raise. This is an illustrative library, not a catalogue of supported integrations or automatic emergency classifications.
Physical security and access
Door opened
An entrance changes from closed to open.
Decide whether the opening needs attention.
Door held open
A door remains open longer than expected.
Check the situation and assign a follow-up if needed.
Motion detected
Movement is reported in a monitored area.
Review the context before deciding whether to act.
Perimeter crossing
A boundary sensor reports a crossing.
Check the location and route a proportionate response.
Video event
A camera flags a person, vehicle or other change.
Review the evidence rather than treating every detection as urgent.
Access declined
An access attempt is not accepted.
Determine whether help or review is needed.
Gate opened
A site gate changes position.
Check expected access and any required follow-up.
Intercom call
A visitor asks for assistance at an entrance.
Connect the request with the right person.
Camera unavailable
A camera stops reporting its normal status.
Assign an equipment check without implying an incident occurred.
Industrial, process and environment
Smoke indication
A detector reports a smoke-related indication.
Follow the site's safety procedures to assess the indication.
Water indication
A leak sensor reports water where it is not expected.
Check the source and coordinate a suitable response.
Temperature change
A reading leaves the expected temperature range.
Review the affected space, process or equipment.
Pressure threshold
A pressure reading crosses a configured threshold.
Check process context and determine the required action.
Vibration change
Equipment vibration differs from its expected range.
Consider inspection or maintenance based on context.
Power interruption
A monitored supply reports an interruption.
Assess affected operations and assign recovery work.
Process threshold
A process measurement crosses a configured limit.
Prioritize the exception using operational context.
Equipment fault
Equipment reports a fault or diagnostic condition.
Assign investigation to an accountable owner.
Level change
A tank or reservoir reaches a configured level.
Check operating limits and plan the next action.
Air-quality change
An environmental reading moves outside the expected range.
Review the reading under the site's operating procedures.
Sensor reading
A sensor reports a new value or change of state.
Interpret the reading in context before creating work.
Humidity change
Humidity leaves the range expected for a space or material.
Check storage or operating conditions.
Machine stopped
A machine changes from running to stopped.
Confirm whether the stop is expected and coordinate any follow-up.
IT, workflow and automation
Job failed
An automated task ends without its expected result.
Find the failure context and assign recovery work.
Job running late
A task has not finished by its expected time.
Check downstream effects and decide whether to intervene.
Job completed
A task reports that its work is complete.
Confirm the result and move dependent work forward.
Service health changed
A service reports a change in health or availability.
Assess the impact before setting priority.
System unavailable
A monitored system stops responding.
Establish ownership and coordinate investigation.
Data transfer failed
A scheduled file or data exchange does not complete.
Check what was missed and who needs to resolve it.
Work queue growing
Pending work accumulates faster than it is completed.
Review capacity, urgency and assignment.
Unusual sign-in event
A sign-in is flagged for review by an existing system.
Route the evidence for an appropriate review; a flag is not proof of compromise.
Certificate nearing expiry
An existing system reports an upcoming certificate expiry.
Assign renewal work before it affects service.
Backup not completed
A scheduled backup does not report completion.
Check the result and assign follow-up.
Communication, service and business
Incoming phone call
A customer or colleague calls the team.
Make it clear who should answer or follow up.
New message
An email or team message requests attention.
Separate actionable requests from background noise.

A customer reports an issue or asks for help.
Give the request an owner and appropriate priority.
Service request
Someone requests a visit, repair or business service.
Clarify the work and route it to the right team.
Approval needed
A decision is waiting for an authorized approver.
Identify the decision owner and what is needed to proceed.

Assign a responsible contact and timely follow-up.
