Ajax MultiTransmitter

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

MultiTransmitter supports various connection types (NC, NO, EOL and, on newer versions, 2EOL and 3EOL), allowing both simple signal contacts and more advanced tamper-resistant configurations.

The device communicates with the hub wirelessly via the encrypted Jeweller protocol, maintaining a connection with the hub at distances of up to ~2,000 m in line of sight.

MultiTransmitter gives legacy wired systems a new lease of life and is ideal for upgrading wired security systems without replacing all 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 types — Supports NC, NO, EOL, 2EOL and 3EOL connections (the latter two require newer firmware).

• Uninterrupted power and protection — Main power supply is 100–240 V AC; a 12 V backup battery (max. 7 Ah) can be used if required, keeping the system running for up to several days during a power outage.

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

• 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 into 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.

• Great 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.
