MultiTransmitter

Module for integrating wired third-party devices into Ajax

FAQ

MultiTransmitter with firmware version 2.13.0 and higher supports the following connection types:

  • 3EOL
  • 2EOL
  • EOL
  • NC
  • NO

MultiTransmitter with firmware version below 2.13.0 only supports NC, NO, and EOL connections.

2EOL and 3EOL connections are available if MultiTransmitter works with Hub Plus, Hub 2, Hub 2 Plus, or Hub Hybrid on OS Malevich 2.13 and higher.

For the Hub model, only NC, NO, and EOL connections are available.

The identifier (ID) is the serial number of the device. It is located under the QR code on the body, board, and packaging of the device.

ID at the bottom of the box

ID under the lid

The ID can also be found in the device states in the Ajax app.

  1. Sign in to the Ajax app.
  2. Select the required hub from the list if you have several of them or if you are using a PRO app.
  3. Go to the Devices menu.
  4. Select a device from the list. Device ID information is located at the bottom of the status screen.

The hub communication range is up to 2,000 meters, provided there are no obstacles.

Please note that any obstacles that impede the radio signal transmission (walls, inter-floor constructions inside large facilities) may significantly reduce the radio communication range.

MultiTransmitter is not compatible with ocBridge Plus, uartBridge, and third-party security central units.

The maximum length of a signal cable to connect a device or a detector is 400 meters (the copper-plated aluminium cable of 0.22 mm² in its cross-section).

The value may vary if a different type of cable is used. No other types of cables have been tested.

Yes. The integration module has 3 power supply lines of 12 V: one dedicated line for fire detectors and two, for other devices.

The total consumption of all connected devices and detectors should not exceed 1 A.

A total of 9 types are available:

Type Icon Note
Intrusion
Fire
Medical help
Panic button
Gas alarm
Tamper alarm
Malfunction

The functionality is available for MultiTransmitter with firmware version 2.13 and higher.

MultiTransmitter must be connected to Hub Plus, Hub 2, Hub 2 Plus or Hub Hybrid on OS Malevich 2.13 and higher. The Hub model does not support this type of connection.

Leakage

Not sent to the security company monitoring station, and to users via SMS.

You can select the type of alarm in the zone settings. Your selection will configure the connected device’s alarm and event notifications and the event codes transmitted to the Central Monitoring Station (CMS) of the security company.

We recommend using a 12 V battery of 4 or 7 Ah. This type of battery requires special racks in the casing.

You can also use similar batteries of a different capacity, of the matching size and a the charging time of no more than 30 hours.

If the battery is charging for more than 40 hours, a notification will be sent to Ajax apps informing that charging takes too long. This type of event is considered a malfunction and displayed in device States.

The maximum battery size installed in the body should be 150 × 64 × 94 mm. The maximum weight is up to 5 kg.

MultiTransmitter is powered from the mains 100–240 V AC; it can also run on a 12 V backup battery.

That the 12 V terminals should not be connected to any power supply units. These terminals are for battery connection only.

Connecting the power supply unit to the 12 V⎓ terminals may damage the MultiTransmitter.

Copied

We recommend connecting one device to one wired zone of the integration module (a total of 18).

With multiple devices connected to one wired zone, the total consumption of all connected devices should not exceed 1 A. If you connect the detectors this way, you will not be able to know which of them has been triggered.

Copied

The MultiTransmitter integration module has 18 wired zones.

With OS Malevich 2.9 update, temporary deactivation of devices without removing them from the system has become available.

Deactivation may be necessary if the device is incorrectly installed or configured, loses connection with the hub, or has failed.

To temporarily deactivate a device, in the Ajax app:

  • Select a hub if you have several of them or if you are using the PRO app.
  • Go to the Devices menu.
  • Select the device from the list.
  • Go to its Settings .
  • Select the type of temporary deactivation:
    • Entirely — the device does not execute system commands or run automation scenarios, and the system ignores device alarms and other notifications.
    • Lid only — the system ignores the notifications on the detector’s tamper button triggering.

The firmware version can be found in the device states in the Ajax app.

  1. Sign in to the Ajax app.
  2. Select the required hub from the list if you have several of them or if you are using a PRO app.
  3. Go to the Devices menu.
  4. Select a device from the list. The firmware version information is located on the status screen at the bottom.
