The new version of MultiTransmitter: 3EOL support and additional alarm types

Introducing a new revision of MultiTransmitter, a module for integrating third-party wired detectors to the Ajax security system. The updated version supports 2EOL and 3EOL connections, more types of alarms, and an extended EOL resistance value range.

The new version of MultiTransmitter will replace the previous one. To avoid confusion, the new devices have different packaging — with a “3EOL” label. The new devices are already available for pre-order from Ajax Systems partners.


Why MultiTransmitter is needed

With MultiTransmitter, the installation engineers and security companies can build a cutting-edge, comprehensive security system based on the wired equipment already installed at the facility.

Owners of outdated wired alarm systems receive control of security modes in a smartphone app, informative notifications, and automation scenarios from Ajax. And installation engineers and security companies can now manage the system settings in Ajax PRO apps: both on–site and remotely.

The new revision features

The new MultiTransmitter revision features are available with the Ajax app update and the OS Malevich 2.13 firmware.

Connection without limits

The updated version of MultiTransmitter supports NC, NO, EOL, 2EOL, and 3EOL connections. This gives more freedom for installation engineers: any wired detector with dry contacts can be connected to the integration module.

More event types of wired devices

  • Intrusion
  • Fire alarm
  • Medical help
  • Panic button
  • Gas alarm
  • Tamper alarm
  • Malfunction
  • Leakage
  • Custom

The new version of MultiTransmitter allows you to connect wired water leaks detectors to the system. Also, the device can now notify users about a service event, without sending the alarm to the security company’s monitoring station. This can be useful to keep track of the water level in a reservoir or the state of smoke machine service outlets.

Extended EOL resistance value range

Installation engineers can now install EOL resistors with resistances from 1 kOhm to 15 kOhm in 100 Ohm increments. The use of non-standard resistance values strengthens protection against sabotage.

For the convenience of installation engineers, we have provided a tool in Ajax apps that measures the resistance of termination resistors and sets recommended values.

When connecting 3EOL devices, we recommend using the following resistance ratio: R for the first resistor, 2*R for the second, 3*R for the third.

What will happen to the previous version of MultiTransmitter

We are stopping production and delivery of the previous version of MultiTransmitter. Technical support and warranty services for these devices remain unchanged.

The new version of MultiTransmitter is available for pre-order. So that users and partners can distinguish the versions from each other, the new devices come in different packaging — with a “3EOL” label.
