What Is Alarm Monitoring?
Alarm monitoring is the method used to alert keyholders, users or a professional monitoring centre when an alarm activates. The right option depends on the property, risk level, response requirements, signalling path and whether the alarm is for a home, business, managed building or higher-risk site.
Some customers only need app notifications and keyholder alerts. Others may need professional monitoring through an Alarm Receiving Centre, often known as an ARC. Sanders Secure can explain the difference and recommend a suitable approach.
We are the installer and maintainer of the alarm system. Where professional ARC monitoring is required, this is provided through a suitable monitoring centre and set up according to the agreed signalling and response arrangements.
App Alerts
App-controlled alarm systems can notify authorised users when the system is armed, disarmed, triggered or reports a fault, depending on the equipment and setup.
Keyholder Notifications
Keyholder notification options can alert nominated people so they can check the property, review the app, respond to the issue or escalate where appropriate.
ARC Monitoring
Professional ARC monitoring allows alarm signals to be received and handled by a monitoring centre, with agreed escalation procedures followed when an activation occurs.
Professional Monitoring Through DSOC
For professional alarm monitoring, Sanders Secure primarily uses DSOC, the Doncaster Security Operations Centre, where suitable for the customer and system design.
DSOC provides Alarm Receiving Centre services, intruder alarm monitoring, fire alarm monitoring and remote CCTV monitoring. They operate as an independent NSI Gold Category One facility.
Using a professional ARC can be useful for customers who need a more structured response than app notifications alone, particularly for commercial premises, managed buildings, higher-risk sites or customers who require agreed escalation procedures.
Important: monitoring arrangements, keyholder response, police response eligibility and emergency escalation all depend on the system design, signalling method, site requirements and agreed response plan.
What Happens During an Alarm Activation?
When a monitored alarm activates, the signal is sent through the agreed signalling path. Depending on the setup, this may be via broadband, mobile data, cellular signalling or a dual-path option.
The response depends on how the system has been configured. This may include contacting nominated keyholders, reviewing confirmed signals, following customer-specific instructions, or escalating to emergency services where the site is eligible and the correct confirmation criteria are met.
Sanders Secure can explain the options clearly before installation so you understand what is monitored, who is contacted and what response is expected.
Alarm Monitoring Options We Can Help With
Sanders Secure can design, install and maintain alarm systems with suitable monitoring and signalling options. We primarily work with professional intruder alarm platforms such as Ajax, Orisec and other suitable systems depending on the site.
Broadband Signalling
Some alarm systems can communicate through the property’s broadband connection, supporting app control, notifications or monitoring where suitable.
Cellular Signalling
Mobile or cellular signalling can provide a communication route where broadband is unavailable, unreliable or where a backup path is required.
Dual-Path Options
Dual-path signalling can combine more than one communication route, helping improve resilience where a higher level of reliability is required.
Ajax alarm monitoring
Ajax systems are a strong option for customers who want app control, push notifications, photo verification and monitoring options through suitable signalling arrangements. Sanders Secure mainly installs Ajax Hub 2 systems, with other Ajax hub options considered where required.
For more information, visit our Ajax wireless alarm systems page.
Orisec and professional alarm monitoring
For wired, hybrid and professional intruder alarm systems, Sanders Secure can specify suitable equipment with app connectivity, signalling modules, keyholder notifications and monitoring options where appropriate.
For new alarm installations, visit our intruder alarm systems page.
Domestic Alarm Monitoring
For homes, monitoring may be as simple as app alerts and keyholder notifications, or it may involve a more structured monitoring arrangement depending on the customer’s needs.
We can help with monitored burglar alarms, wireless Ajax systems, app-controlled alarms, alarm takeovers and upgrades to older systems that no longer communicate reliably.
For home-focused installation information, visit our burglar alarms in Plymouth page.
Commercial Alarm Monitoring
For businesses, warehouses, offices, hospitality venues, schools, managed buildings and commercial units, professional monitoring can provide a clearer response process when an alarm activates.
Commercial monitoring may be suitable where there are valuable assets, staff safety considerations, vulnerable premises, out-of-hours risks or a need for agreed escalation procedures.
Sanders Secure can also support wider commercial security requirements, including commercial CCTV systems and access control.
Monitoring Needs Maintenance Too
A monitored alarm system is only useful if the alarm, signalling equipment, detectors, batteries and communication paths are maintained correctly.
Sanders Secure can service monitored alarm systems, check signalling where suitable, review battery condition, test detectors, confirm app operation and advise on upgrades where older systems no longer meet the customer’s needs.
If you have moved into a property with an existing monitored alarm or inherited a system from another company, we may be able to assess it and advise on takeover options.
For existing systems, visit our alarm servicing and takeovers page.
Alarm Monitoring FAQs
Do I need professional alarm monitoring?
Not always. Some customers only need app alerts and keyholder notifications. Professional monitoring may be more suitable for commercial premises, higher-risk sites, managed buildings or customers who need a structured response process.
What is an Alarm Receiving Centre?
An Alarm Receiving Centre, or ARC, is a professional monitoring centre that receives alarm signals and follows agreed response instructions when an activation occurs.
Do you provide the monitoring yourselves?
Sanders Secure designs, installs and maintains the alarm system. Where professional ARC monitoring is required, the monitoring is provided through a suitable Alarm Receiving Centre such as DSOC, subject to the system and monitoring requirements.
Can Ajax alarms be monitored?
Yes. Suitable Ajax alarm systems can provide app alerts, keyholder notifications, photo verification and monitoring options through appropriate signalling arrangements.
Can an existing alarm be upgraded for monitoring?
In some cases, yes. This depends on the control panel, available communication modules, signalling requirements, system condition and whether the existing equipment is still supported.
Can monitored alarms call the police?
Police response depends on eligibility, correct system design, confirmation requirements, registration and the agreed monitoring arrangement. It should not be assumed that every monitored alarm automatically receives police response.
MONITORED ALARM SYSTEMS
At Sanders Secure, we design monitored alarm systems around the customer, the property and the response required.
We will explain the difference between app alerts, keyholder notifications and professional ARC monitoring so you can choose the most suitable option.
- Designed around the site: monitoring options should match the building, risk and users.
- Suitable signalling: broadband, cellular and dual-path options can be considered where appropriate.
- Professional ARC options: we primarily use DSOC for professional monitoring where suitable.
- Ongoing maintenance: servicing helps keep the alarm and signalling equipment reliable.
- Clear advice: we explain what happens during an activation and what response is expected.
