Ajax MultiTransmitter Wireless Smart Home Integration Module

The Ajax MultiTransmitter is a wireless integration module designed to modernize existing wired alarm systems by connecting them to the Ajax security ecosystem. This wall-mounted device allows users to retain their current wired detectors while gaining access to advanced smart home features, remote control via the Ajax app, and comprehensive security management.

Advantages

The MultiTransmitter breathes new life into outdated wired security setups, allowing for a seamless transition to a modern, app-controlled system without the need to replace all existing hardware. It supports a wide range of third-party devices, including perimeter infrared detectors, gas sensors, and thermostats, which can be integrated into the Ajax hub. The module ensures reliable communication through the encrypted Jeweller radio protocol, which features anti-jamming capabilities and automatic frequency switching. Furthermore, the system provides detailed, data-rich notifications for various alarm types, such as fire, intrusion, or gas leaks, ensuring users are always informed about the specific nature and location of an event. The device is also built with robust anti-sabotage protections, including tamper detection and a backup battery that maintains operation for up to four days during power outages.

Suitable for

• Modernizing legacy wired alarm systems
• Integrating third-party wired sensors into the Ajax ecosystem
• Extending security coverage in areas where wireless signals are obstructed
• Creating automated security scenarios for smart homes

When it may not be suitable

This device is specifically designed for integrating wired components into an Ajax system and is not intended for standalone operation without a compatible Ajax hub. It may not be suitable for environments where the distance between the wired sensors and the MultiTransmitter exceeds the 400-meter wiring limit.

Key specifications

• Operating frequency: 868 - 868.6 MHz
• Maximum wire length: 400 meters
• Mounting type: Wall-mounted
• Backup power: Up to 4 days of operation
• Communication protocol: Encrypted Jeweller radio technology
• Dimensions: 196 mm x 100 mm x 238 mm

How to use

Installation is designed to be straightforward for professionals. The module connects to the Ajax hub by scanning a QR code within the mobile application. When connecting wired devices, the system automatically detects the configuration, eliminating the need for manual resistor value calculations. The installer can configure all settings, including alarm types and room assignments, directly through the PRO-app, either on-site or remotely.

What to consider before purchase

• Ensure compatibility with your existing wired alarm sensors
• Verify that an Ajax hub is available to manage the integration
• Check the cable length requirements for your specific installation site
• Confirm the availability of a stable power source for the module

Usage recommendations: Regularly test the connection of all wired devices after installation and ensure the backup battery is maintained to guarantee continuous protection during power failures.
