App alerts versus professional alarm monitoring
An app notification goes to the user. Professional monitoring sends agreed alarm events through a monitored signalling route with a defined keyholder process.

The direct answer
An app alert notifies the people logged into the system. Professional monitoring sends agreed events through a monitored signalling route so an alarm receiving centre can follow the confirmed contact or keyholder process.
Neither option should be described with vague promises. The customer needs to know which events are transmitted, who is contacted, what supervision is provided and what happens when contacts cannot be reached.
App notifications
App control is useful for arming, event history, user management and direct alerts. Its effectiveness depends on the user’s phone, data connection, notification settings, availability and willingness to respond.
It can suit customers who want direct control, but it is not the same service as a monitored signalling route.
Professional monitoring
A suitable maintained system communicates with the monitoring route and sends agreed alarm events. Keyholder details and the response process are recorded as part of the service.
- Alarm event signalling
- Keyholder contact process
- System or communication supervision where included
- Defined contact records
- Maintenance and compatibility requirements
- Clear renewal and service scope
What monitoring does not automatically mean
Professional monitoring follows the signalling, keyholder and escalation arrangements agreed for the individual system. It should not be treated as a guarantee that somebody will attend every activation.
Choosing the route
Consider who needs to know about an alarm, whether phones can be unavailable, who holds keys, how quickly contacts change and whether the property is residential, commercial or multi-site.
NOX can assess monitoring compatibility for new Ajax systems and suitable existing alarms, subject to maintenance, communication and takeover requirements.

Common questions
Does professional monitoring guarantee attendance?
No. The exact signalling, keyholder and escalation process must be agreed for the individual system, and attendance should not be assumed.
Can an existing alarm be monitored?
Potentially, subject to compatibility, communication equipment, maintenance and a takeover assessment.
Does NOX provide system servicing and takeover support in Chesterfield and Derbyshire?
Yes, subject to the system type, access, condition and parts support. An initial inspection may be needed before ongoing support is confirmed.
Can NOX support a system installed by another company?
Often yes. Existing equipment is assessed before servicing, monitoring, repairs or a phased upgrade are agreed.
