MultiTransmitter User Manual
Updated February 23, 2021
MultiTransmitter is an integration module with 18 wired zones for connecting third-party detectors to the Ajax security system. To protect against dismantling, MultiTransmitter is equipped with two tampers. It is powered from the mains 100­240 V AC, and can also run on a 12 V backup battery. It can supply 12 V power to connected detectors. MultiTransmitter operates as part of the Ajax security system by connecting via the Jeweller secure radio communication protocol to the hub. The hub communication range is up to 2,000 meters provided there are no obstacles. If jamming or interference is detected, the "high level of interference at Jeweller frequencies" event is transmitted to the central monitoring station of the security company and system users.
What jamming of a security system is
Not compatible with ocBridge Plus, uartBridge, and third-party security central units

The device connects to the hub and is con gured through Ajax apps on iOS, Android, macOS, and Windows. All alarms and user events are reported by push noti cations, SMS, and calls if enabled. Ajax security system can be connected to the central monitoring station of the security company. The list of authorized partners is available here.

Operating principle
MultiTransmitter is designed for connecting third-party wired detectors and devices to the Ajax security system. The integration module receives information about alarms and triggering of detector tampers via wires connected to the terminals.

MultiTransmitter can be used to connect panic and medical alarm buttons, indoor and outdoor motion detectors, as well as detectors tracking opening, vibration, breaking, re, gas, leakage, etc. The type of device is indicated in the zone settings. The text of noti cations about alarms and events of the connected device, as well as event codes transmitted to the Central Monitoring Station (CMS) of the security company depend on the selected device type.
A total of 6 types of devices are available:

Icon

Tamper

Intrusion alarm

Fire alarm

Medical alarm

Panic button Gas concentration alarm

MultiTransmitter has 18 wired zones. The number of connected devices depends on their power consumption. The total maximum current consumption of all connected devices or detectors is 1 A.
Supported connection types:

Designation NO NC EOL (NC with resistors) EOL (NO with resistors)

Type Normally open Normally closed. Without resistors Normally closed. With resistors Normally open. With resistors

How to connect a wired detector or device to MultiTransmitter
The integration module has 3 power supply lines of 12 V: one dedicated line for re detectors and two -- for other devices.

After the re alarm, re detectors need a power reset to restore normal operation. Therefore, the re detectors power supply should only be connected to a dedicated line. Also, avoid connecting other detectors and devices to power terminals of re detectors as this may lead to false alarms or incorrect operation of the devices.

Event transmission to the monitoring station
Ajax security system can connect to the CMS and transmit alarms to the monitoring station in Sur-Gard (ContactID) and SIA protocol formats.
The loop (zone) number of the integration module and the devices connected to it can be found in Ajax apps, in the Groups menu of the hub settings.
To learn the loop (zone) number, select the group in which the integration module is located or the desired connected device. The Device Number (or DeviceIndex in Ajax PRO Desktop) corresponds to the loop (zone) number.

Connecting to the hub
For the Ajax security system, MultiTransmitter acts as a single device and each connected device or detector occupies a single slot in the limited number of the hub devices -- 100 in Hub and Hub 2, 150 in Hub Plus, and 200 in Hub 2 Plus.
Wired detectors can be connected to MultiTransmitter both before and after connecting the module to the hub.
Before starting connection
1. Install the Ajax app. Create an account. Add a hub to the app and create at least one room.
2. Check that the hub is on and has access to the internet (via Ethernet cable, Wi-Fi, and/or mobile network). You can do this in the Ajax app or by looking at the hub logo on the front panel. The logo should light up white or green if the hub is connected to the network.
3. Ensure that the hub is disarmed and does not start updates by checking its status in the app.
Only users with administrator rights can add MultiTransmitter to the hub.
In order to connect MultiTransmitter
1. Go to the Devices tab in the Ajax app and click Add Device. 2. Name the integration module, scan or enter the QR code manually (located
on the body and packaging), and select the placement room. 3. Click Add; the countdown will begin. 4. Turn on MultiTransmitter by holding the power button for 3 seconds. Keep in
mind that the request to connect to the hub is transmitted only when the integration module is turning on.

For the detection and pairing to occur, the integration module should be located within the coverage area of the hub's wireless network (at the same guarded object).

If the connection has failed, disconnect MultiTransmitter for 5 seconds and try again.
If the integration module has already been assigned to another hub, turn off the integration module, and then follow the standard addition procedure.
The connected integration module will appear in the app, in the hub's list of devices. Updating device statuses in the list depends on the ping time de ned in Jeweller settings. The default value is 36 seconds.

Connecting wired detectors and devices to MultiTransmitter
How to connect a wired detector or device

When connecting third-party detectors and devices, do not twist the wires together, but solder them. The ends of wires of the devices or detectors, which will be inserted into the integration module terminals should be tinned or crimped with a special sleeve.

1. Select the MultiTransmitter zone to which you would like to connect a detector or device.
2. Route the wires of the detector or device into the integration module body. 3. Connect a wired detector or device to the appropriate MultiTransmitter
terminals. The wiring diagram can be found in the User Guide provided by the manufacturer of the wired detector or device. 4. Securely fasten the cable to the terminals.
How to connect a wired detector or device to MultiTransmitter

If the detector or device requires 12 V power supply for operation, it can be connected to the power terminals of the corresponding MultiTransmitter zone. Separate terminals are provided for re detectors. Do not connect the external power supply to the detector power terminals, as this may damage the device.

How to add a wired detector or device
1. In the Ajax app, go to the Devices tab .

2. Select MultiTransmitter in the device list. 3. Click on Devices. 4. Click Add Wired Device. 5. Name the device or detector, select the wired zone to which the device or
detector is connected, and select a placement room and a group. 6. Click Add. The device or detector will be then added within 30 seconds. If
for some reason this does not happen, try again. If you encounter connection problems, contact Support Service.
MultiTransmitter functionality test
Integration module functionality tests do not begin immediately, but not later than over a single ping period of the hub detector (36 seconds with the standard settings of the hub). You can change the ping period of devices in the Jeweller menu of the hub settings.
Tests are available in the device settings menu (Ajax app  Devices  MultiTransmitter  Settings ):
Jeweller Signal Strength Test Attenuation Test
Selecting MultiTransmitter placement
The placement of the integration module determines its distance from the hub and the presence of obstacles between them that impede the passage of the radio signal: walls, inter- oor constructions, or large-sized objects located in the room.
Be sure to check the signal strength at the installation site. If the signal strength is low (a single bar), we cannot guarantee a stable operation of the security system! At the very least, relocate the device as repositioning even by 20 cm can signi cantly improve the signal reception.

If poor or unstable signal strength is still reported after the relocation of the device, use the ReX radio signal range extender of the security system.
When choosing the installation location, consider the distance between the integration module and wired devices or detectors -- the cable length should be su cient for connection. The maximum length of the signal cable for connecting a device or a detector is 400 meters (cable material is copper-plated aluminum, cross-section is 0.22 mm²). The value may vary if a different type of cable is used. No tests were conducted on other types of cables.
MultiTransmitter installation
Prior to mounting the integration module, ensure that you have selected the optimal location and that it corresponds to this manual!
The body allows mounting the integration module on a vertical surface.
In order to install a module:
1. Secure the body to the surface with bundled screws using at least two xing points. In order for the integration module tamper to respond to a dismantling attempt, be sure to x the body at the point with the perforated section.
2. Install the MultiTransmitter card into the body on the racks. 3. If available, connect a backup battery. Don't connect external power supply!
We recommend using a 12 V battery with a capacity of 4 or 7 Ah. For such batteries, special racks in the body are designed. You can also use similar batteries of a different capacity, of matching size, with the maximum full charge time of no more than 30 hours. The maximum battery size for installation in the body is 150 × 64 × 94 mm.
4. Connect wired detectors and devices to the integration module. Turn on the integration module.

5. Install the lid on the body and secure it with the bundled screws.
After installation, be sure to check the MultiTransmitter tamper status in the Ajax app.

Do not install the integration module:
Outdoors. Near metal objects and mirrors causing radio signal attenuation or screening. Inside premises with temperature and humidity outside the permissible limits. At a distance of less than 1 meter from the hub.

Maintenance
Check the functionality of the integration module regularly. Clean the body from dust, cobwebs, and other contaminants as they emerge. Use a soft dry cloth that is suitable for equipment care. Do not use any substances containing alcohol, acetone, gasoline, and other active solvents to clean the device.
