MultiTransmitter User Manual
Updated December 29, 2020
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 100–
240 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
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.

The device connects to the hub and is configured through on iOS,
Android, macOS, and Windows. All alarms and user events are reported by push
notifications, 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 .

LED indication

MultiTransmitter LED indicator may light up white, red, or green, depending on the
status of the device. Please note that the LED indicator is not visible when the body
lid is closed, but the status of the device can be found in the Ajax app.

If MultiTransmitter is not assigned to the hub or has lost connection with it, the integration
module will not give an indication of the battery status or the presence of external power
supply.
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, fire, gas, leakage, etc. The type of device is indicated in the zone settings.
The text of notifications 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:
Type 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 Type
NO Normally open
NC Normally closed. Without resistors
EOL (NC with resistors) Normally closed. With resistors
EOL (NO with resistors) Normally open. With resistors
The integration module has 3 power supply lines of 12 V: one dedicated line for fire
detectors and two — for other devices.
After the fire alarm, fire detectors need a power reset to restore normal operation. Therefore,
the fire detectors power supply should only be connected to a dedicated line. Also, avoid
connecting other detectors and devices to power terminals of fire 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
) corresponds to the loop (zone) number.
Connecting to the hub
Ajax PRO Desktop

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 and , 150 in , and 200 in .
Wired detectors can be connected to MultiTransmitter both before and after connecting the
module to the hub.
Before starting connection
Only users with administrator rights can add MultiTransmitter to the hub.
In order to connect MultiTransmitter
Hub Hub 2 Hub Plus Hub 2 Plus
1. Install the . . Add a hub to the app and create at
least one room.
Ajax app Create an account
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.
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 defined in
Jeweller settings. The default value is 36 seconds.
