MultiTransmitter Jeweller

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
Auxiliary alarm
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.
Flooding		In the case of flooding, a smart water shutoff valve Ajax WaterStop can stop the water supply. Controls it in Ajax apps, through a button on the enclosure, a lever on a shutoff valve, as well as automation scenarios.
Custom		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.

Supported connection types:

Supported detector types:

• Pulse
• Bistable

We recommend using a 12 V⎓ battery of 4 or 7 A⋅h. 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 with a 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.

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.

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.

The MultiTransmitter integration module has 18 wired zones.

With OS Malevich 2.9 update, permanent 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 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 permanent 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 space 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.
