Using an Older ADEMCO Alarm System? Here’s When (and Why) You Should Upgrade

Across Vancouver and the Lower Mainland, many homes and commercial properties are still protected by older ADEMCO alarm systems. These systems were trusted for decades—but if yours is more than 20 years old, it likely lacks modern features, speed, and integration.

At ProActive Integrated Security, we specialize in upgrading aging security systems to modern solutions using leading brands like DSC, 2GIG, and integrated surveillance options like Hikvision. Whether you own a home, manage a business, or are part of a strata council, upgrading your ADEMCO system can bring immediate benefits in reliability, usability, and protection.

What Is an ADEMCO Alarm System?

ADEMCO (Alarm Device Manufacturing Company) was a major manufacturer of hardwired alarm panels and sensors. It became part of Honeywell and continued producing well-regarded systems like:

• • Vista 10SE, 15P, and 20P panels
  • 4110 and 4120 series panels
  • Lynx Plus and Lynx Touch

These systems were commonly installed in homes and businesses throughout the 1990s and early 2000s. Most rely on landline phone communication, lack remote control features, and are incompatible with today’s smart home integrations.

While they may still function, they fall short in terms of reliability, flexibility, and monitoring capability.

Signs Your ADEMCO System Needs an Upgrade

Here are the most common indicators your system is due for replacement:

You're Having Trouble Finding Parts or Service

Many older ADEMCO systems are discontinued, and replacement parts can be hard to find—or no longer supported. Programming changes or service calls often require outdated tools or knowledge.

You Still Rely on a Landline

If your alarm system depends on a traditional phone line, it's more vulnerable. Burglars can disable your system simply by cutting the wire. Landline monitoring is also slower and doesn’t meet current ULC standards.

Frequent False Alarms or Trouble Codes

Aging sensors and wiring can trigger false alarms or produce "trouble" notifications on your keypad. Over time, these nuisance alerts reduce confidence in your system and put you at risk of real threats being ignored.

It’s Difficult to Use or Manage

Older systems often require confusing keypad commands. There’s no mobile app, no push notifications, and no easy way to manage users, arm remotely, or confirm your system is secure when you're away.

Your System Can’t Be ULC Monitored

If you need ULC-certified monitoring for insurance or code compliance—especially in commercial or multi-unit residential buildings—your current ADEMCO system may not qualify.

What Are Your Upgrade Options?

Retrofit Using Your Existing Hardware

In many cases, we can replace your ADEMCO panel and keypad while retaining your existing wiring and door/window contacts. This is a cost-effective approach that modernizes your system without a complete rebuild.

We often recommend:

• • DSC PowerSeries Neo for hybrid systems
  • 2GIG GC2 or GC3 for wireless flexibility and full mobile control

Switch to a Modern Wireless System

If your ADEMCO system is too outdated or damaged to retrofit, we can install a wireless system that provides superior functionality and ease of use. These systems offer:

• • Cellular communication (no landline required)
  • Integration with smart locks, thermostats, and lighting
  • Easy control via smartphone or tablet
  • Optional integration with Hikvision security cameras and Kantech access control

Why Upgrade Now?

Modern alarm systems provide:

Faster emergency response – Cellular and IP communication reaches monitoring centers faster and more reliably than landlines.

Remote access – Control your alarm system from anywhere. Arm and disarm your system remotely, receive alerts, and check system status.

Smart home and business integration – Combine your alarm with lighting, locks, thermostats, garage doors, and more.

Improved reliability – Fewer false alarms, better diagnostics, and easier maintenance.

Real-World Example: Vancouver Homeowner Upgrades After Attempted Break-In

A homeowner in Vancouver’s Mount Pleasant neighborhood contacted us after discovering a forced-open basement window one morning. Their existing ADEMCO system had failed to detect or respond to the intrusion attempt. The system was still active, but relied on outdated wired sensors and a landline connection that had been disrupted.

They had no mobile alerts and no idea when the attempt occurred.

We upgraded their system to a 2GIG GC3 touchscreen panel, added wireless motion detectors, and installed Hikvision cameras to monitor blind spots around the property. With a new cellular connection, they now receive instant alerts, have full mobile access, and can view live or recorded video remotely.

The result? Peace of mind, real-time control, and confidence that their home is better protected.

Real-World Example: Vancouver Retailer Upgrades After Overnight Break-In

We also worked with a retail business owner in East Vancouver whose store was broken into after hours. Their ADEMCO system had functioned for years, but during the break-in, the intruder simply cut the landline.

Because the system lacked remote alerts or camera coverage, the owner didn’t discover the break-in until arriving at the store the next morning.

We replaced the panel with a 2GIG GC3 system, switched to cellular monitoring, and added Hikvision cameras with mobile access. The upgraded system now alerts the owner immediately and provides ULC-compliant monitoring to meet insurance requirements.
