Ajax MultiTransmitter

MultiTransmitter is an integration module for connecting third-party wired detectors and devices (e.g. door/window contacts, motion detectors, gas or water leak detectors, fire or intruder alarm systems, etc.) to the Ajax Security System. It turns legacy wired installations into part of a modern smart home or security system: you can control and monitor everything from the mobile app, and view and configure the status of all devices in real time.

MultiTransmitter supports a range of connection types (NC, NO, EOL, plus 2EOL and 3EOL on newer versions), handling both simple signal contacts and more advanced tamper-proof configurations.

The device communicates wirelessly with the hub via the encrypted Jeweller protocol, providing control and supervision communication over distances of up to ~2,000 m in line of sight.

MultiTransmitter gives an old wired system a new lease of life, making it ideal for upgrading wired security systems without replacing all the existing detectors.

Key features and benefits

• Universal wired connectivity: Connect existing wired detectors and devices (door/window contacts, motion detectors, leak or smoke detectors, gas/water detectors, etc.).

• Versatile connection options: Supports NC, NO, EOL, 2EOL and 3EOL connections (the latter require newer firmware).

• Continuous power and protection: The main power supply is 100–240 V AC; a 12 V battery (max. 7 Ah) can be added if needed, keeping the module running for up to several days during a power outage.

• Tamper protection: The device has two physical tamper switches (for removal of the enclosure and removal of the cover), and any loss of connection with the detectors is detected instantly.

• Flexible automation and monitoring: For each connected detector, you can assign an alarm type (intrusion, fire, gas leak, etc.) and a room, resulting in accurate and informative notifications (push, SMS, monitoring station, etc.).

• Integration with the Ajax ecosystem: The device is compatible with all Ajax hubs and frequency versions according to region.

Technical specifications

Why choose MultiTransmitter

• If you already have legacy wired detectors, MultiTransmitter lets you keep using them while adding modern smart alarms and monitoring.

• High flexibility: supports multiple connection and configuration types and works with a wide range of detectors and devices (door and window contacts, motion detectors, fire or gas alarms, leak detectors, etc.).

• Build a hybrid system: combine wired and wireless detectors in a single Ajax system, control everything from one app and get the most out of automation.
