Many homes and businesses still rely on wired alarm systems that were installed years ago. While these systems may still function, they often lack modern features such as mobile control, real-time alerts, automation, and professional remote management. Replacing an entire wired system can be costly and disruptive—but with MultiTransmitter Jeweller, that’s no longer necessary.
MultiTransmitter Jeweller allows existing wired alarm devices to be seamlessly integrated into the Ajax security ecosystem, giving outdated systems a powerful second life without abandoning the equipment already in place.
Modern Security Control via Smartphone
By connecting wired detectors to MultiTransmitter Jeweller, users gain full control of their security system through the Ajax mobile app. This includes instant notifications, detailed event reports, and the ability to arm or disarm the system remotely.
Installers can configure and manage the system using the Ajax PRO app—either on-site or remotely—making setup faster and ongoing support more efficient.
Combine Wired and Wireless Security
MultiTransmitter Jeweller makes it possible to build a hybrid security system, combining existing wired devices with Ajax wireless technology. Wired motion detectors, perimeter sensors, fire alarms, gas sensors, and more can work alongside Ajax keypads, automation devices, flood sensors, and cameras—all managed in one app.
This flexibility allows properties to expand their security coverage without rewiring or rebuilding infrastructure.
One Module, Multiple Capabilities
Designed for professional installations, MultiTransmitter Jeweller supports up to 18 wired zones and multiple connection types (NO, NC, EOL, 2EOL, 3EOL). It includes:
Dedicated power lines for intrusion and fire detectors
Space for a backup battery (up to 7 Ah)
Dual tamper protection against opening or removal
Sabotage detection for cable cutting, disconnection, or short circuits
If mains power is lost, the backup battery can keep the system running for up to four days, ensuring uninterrupted protection.
Faster, Smarter Alarm Information
Unlike traditional systems that provide limited alerts, MultiTransmitter Jeweller delivers data-rich notifications. Each wired device can be assigned a name, room, and alarm type, allowing users and monitoring professionals to know exactly what happened and where.
Alarm events—including intrusion, fire, gas, panic, leakage, or malfunction—are instantly sent via push notification, SMS, and to the central monitoring station with accurate event codes.
Reliable Wireless Communication Without Compromise
MultiTransmitter Jeweller communicates with Ajax hubs using the encrypted Jeweller radio protocol, delivering alarms in as little as 0.15 seconds. The system detects jamming attempts, automatically switches frequencies, and maintains stable communication at distances of up to 2,000 meters in open space.
For large or complex sites, Ajax radio range extenders can expand coverage up to 35 km², while wired devices connected through MultiTransmitter can reach distances of up to 400 meters.
Automated Security That Responds Instantly
When paired with Ajax automation scenarios, MultiTransmitter Jeweller enables a smarter response to threats. The system can automatically:
Arm or disarm on a schedule
Turn on lights when motion is detected
Shut off power or gas at the first sign of fire
Trigger actions without waiting for manual intervention
This transforms a traditional alarm system into a smart security and safety solution.
Easy Installation, Professional Results
Installation is designed to be straightforward for security professionals. The module is added to the system by scanning a QR code, mounted on a wall, and fully configured in the app. The system even alerts installers if a wired device is connected incorrectly—saving time and reducing errors.
Integrated with Professional Monitoring
When installed by WC Security Services, MultiTransmitter Jeweller becomes part of a fully monitored security solution. Alarms are received at our 24-hour Control Centre, where trained operators assess events and coordinate appropriate response, including mobile patrol dispatch when required.
Upgrade Without Starting Over
MultiTransmitter Jeweller is the ideal solution for properties looking to modernize security without replacing existing wired equipment. It delivers smarter control, faster alerts, and professional monitoring—while preserving previous investments.
