When it comes to protecting your home or business, the right security system is about more than just deterrents—it’s about response. At Rossells Security Solutions, we’re often asked one key question: “What’s the difference between monitored and unmonitored alarms?”

The answer can shape not only how secure your property is, but also how supported you feel in the event of an emergency. In this article, we’ll break down both types of alarm systems in detail, helping you understand their pros, cons, and which might be right for your needs.

As a trusted provider of security systems across Leicester and the East Midlands, Rossells Security Solutions offers both monitored and unmonitored alarm systems, as well as a wide range of integrated services such as CCTV installation, access control, smart security upgrades, and commercial locksmithing. Whether you're looking to protect your home, office, warehouse, or retail space, we’re here to guide you.

What Is a Monitored Alarm System?

A monitored alarm system is connected to a 24/7 monitoring centre that receives alerts when the alarm is triggered. Once an alarm is activated—whether from a door sensor, motion detector, or smoke alarm—a signal is immediately sent to a monitoring team.

How Monitored Alarms Work:

Detection – The system picks up an intrusion or unusual activity.
Signal transmission – An alert is sent to the monitoring centre.
Verification – The centre may attempt to contact you or check video feeds (if CCTV is integrated).
Response – Emergency services or a keyholder is contacted if needed.

At Rossells, we use accredited monitoring centres that follow BS EN 50518 and offer police-response options, adding a critical layer of intervention that you simply don’t get with unmonitored systems.

What Is an Unmonitored Alarm System?

An unmonitored alarm system (sometimes called a “bells-only alarm”) triggers a loud siren when activated. However, it does not alert a third-party service or send real-time notifications to you or a response team.

How Unmonitored Alarms Work:

Detection – A sensor is triggered.
Sound – An internal and/or external siren goes off.
Awareness – The hope is that the noise deters the intruder and alerts neighbours.

There’s no automatic alert to the police or a monitoring centre unless someone nearby takes action. It’s a more budget-friendly option but relies on audible deterrents rather than guaranteed action.

Key Differences Between Monitored and Unmonitored Alarms

Let’s break down the main differences between these two alarm systems:

Feature	Monitored Alarm Systems	Unmonitored Alarm Systems
24/7 Monitoring	Yes	No
Response Time	Immediate (via control room)	Depends on neighbours or passers-by
Police Notification	Yes (if integrated)	No
Mobile Alerts	Yes (via smart apps)	Sometimes, if smart-enabled
Installation Cost	Higher	Lower
Monthly Fees	Yes (monitoring contract)	No
Reliability	High (with dual path signalling options)	Variable (especially if disconnected)
Insurance Premiums	Often reduced with police-monitored systems	Less likely to influence premiums

When Should You Choose a Monitored Alarm?

Monitored alarms are the gold standard for security-conscious households and businesses. We typically recommend them if:

You own a high-value property or business premises.
Your area has a history of break-ins or criminal activity.
You want peace of mind that someone is always watching.
You’re often away from your property (e.g. travelling or holiday homes).
You need a system that qualifies for insurance discounts or satisfies specific compliance.

At Rossells, our monitored alarm solutions are often used in office complexes, warehouses, retail units, and high-end homes across Leicester and surrounding counties. When combined with remote CCTV monitoring, it offers an ironclad security solution.

When Is an Unmonitored Alarm Enough?

An unmonitored alarm may suit:

Smaller properties or flats in secure buildings.
Budget-conscious homeowners wanting basic deterrence.
Locations where neighbours are nearby and likely to act on an alarm.
Temporary setups or rental properties.

While unmonitored systems do offer a loud deterrent, they don’t guarantee action. If you choose this route, we strongly advise pairing it with CCTV installation, smart doorbells, or motion-activated floodlights—all of which we provide and install.

Benefits of Monitored Alarms

✅ 24/7 Peace of Mind

Knowing a professional team is always watching gives you a constant layer of protection.

✅ Emergency Services Contacted Automatically

You don’t have to rely on others to take action. If your system includes verified police response, help is dispatched immediately.

✅ Smart Notifications

With systems like Texecom and Pyronix (which we install), you’ll receive instant mobile alerts through secure apps, even when abroad.

✅ Compliance & Insurance

Insurers may require professional monitoring for certain high-value policies, and it can reduce premiums.

Benefits of Unmonitored Alarms

✅ No Ongoing Fees

Once installed, there are no monthly costs—ideal for those wanting to keep things simple.

✅ Quick Installation

Unmonitored systems can be set up faster, and in some cases, as wireless alarm systems, can be relocated easily.

✅ Effective Deterrent

A loud siren can still stop many intruders in their tracks—especially when combined with other visible security like CCTV or signage.

Should I Upgrade from Unmonitored to Monitored?

We speak to many customers who started with basic security and are now ready to upgrade. Some signs that it might be time include:

You've experienced a recent break-in or suspicious activity.
You’ve invested in new assets—vehicles, tools, tech, etc.
You're away more often, leaving the property vulnerable.
You want better integration with smart home technology.
You’ve moved into a detached or isolated property.

Rossells offers alarm upgrades and system takeovers for both residential and commercial clients. We’ll assess your current setup and provide recommendations based on risk level, property layout, and budget.

How Much Does It Cost?

Monitored Alarms

Installation: Typically from £800–£1,500+, depending on size and complexity.

CCTV Systems – We install HD and smart-enabled cameras with remote viewing capabilities.
Access Control – For offices, apartment blocks, or gated properties.
Smart Doorbells – Visual confirmation of visitors or deliveries.

Final Thoughts: Which Alarm Is Right for You?

Choosing between a monitored and unmonitored alarm system depends on your individual needs, risk level, and peace of mind.

If you want 24/7 backup, rapid response, and smart alerts, then a monitored alarm is the best investment. If you’re looking for a budget-friendly deterrent and live in a low-risk area, an unmonitored system paired with CCTV may suffice.
