Existing-system service
Start with the system you already own. We review failures, communication paths, aging controls and monitoring before defining the upgrade path.
Ajax alarm service, takeover and modernization for homes and businesses with existing security systems. We evaluate your current equipment first, preserve compatible devices when technically appropriate, and upgrade the parts that actually need it.
National Ajax installation and service coordination available. Where prohibited, call for details. Licensed vendors are utilized when needed.

MultiTransmitter can create an integration path for compatible third-party wired alarm devices. That can make Ajax especially compelling for properties that already have useful contacts, motion detectors, glass-break devices, panic devices, sirens or field wiring.
Start with the system you already own. We review failures, communication paths, aging controls and monitoring before defining the upgrade path.
MotionCam can add visual context to supported alarm events when the hub, device and monitoring configuration support it.
We can evaluate monitoring options as part of a service or modernization plan rather than forcing a complete new-system sale.
This is not a sales-volume ranking or a promise that every device is appropriate for every project. Exact compatibility, region, frequency, firmware, listings and system configuration must be reviewed.

Modern Ajax hub for intrusion, app control and supported photo verification.

Feature-rich control panel with multiple communication paths and compatible MotionCam support.

Compact opening detection for doors, windows and protected openings.

Adds shock and tilt awareness for selected intrusion applications.

Indoor motion detection designed for modern Ajax intrusion systems.

Outdoor detection plus supported photo-on-demand and event verification capabilities.

Touchscreen control for supported Ajax systems, including compatible credential and smartphone access options.

Indoor audible notification for supported Ajax security systems.

Outdoor audible and visual alarm signaling for supported configurations.

A powerful modernization path that can integrate compatible third-party wired detectors after technical review.

Extends supported Ajax radio coverage and can support photo transmission in compatible configurations.

Smoke, heat and CO options exist within the family. Exact model, listing, code and jurisdiction requirements must be reviewed.

Compact leak detection for selected homes, facilities and equipment areas.
Warehouses, restaurants, retail, hotels, multifamily, automotive, medical offices, schools, churches, industrial facilities and commercial offices can all have different takeover and service priorities.
Homeowners can evaluate existing sensors, app control, photo verification, sirens, leak detection and monitoring without assuming the entire existing system must be discarded.
Potentially. The correct path depends on your existing panel, field devices, wiring, power, monitoring needs and exact Ajax components. MultiTransmitter can provide a takeover path for compatible wired devices, but compatibility must be verified first.
Not automatically. Our service-first approach is to evaluate what is usable and preserve compatible equipment when technically appropriate.
Some existing devices may be candidates for integration or reuse, but we do not make blanket compatibility promises by brand. A technical review is required.
Supported MotionCam models can provide photo verification and related image features when paired with compatible hubs and system configurations.
Monitoring options depend on system configuration, service area and monitoring integration. We review monitoring as part of the takeover or upgrade plan.
Security First Alarm can coordinate Ajax installation and service projects across the United States. Where prohibited, call for details. Licensed vendors are utilized when needed.
Ajax offers fire and life-safety devices, but commercial fire alarm compliance depends on the exact listed equipment, system design, code requirements and authority having jurisdiction. Fire applications require separate technical and code review.
Send the property location, current alarm brand or model if known, monitoring status, problem you are trying to solve, and whether you want to preserve existing wired devices.
