AJAX 20354 MultiTransmitter Module User Manual

MulTransmitter User Manual

Update 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 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 Oxbridge Plus, uart Bridge, and third-party security central units

The device connects to the hub and is configured through Ajax apps 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 here.

If Multaransmitter 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 an 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.

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

---|---
Tamper|
Intrusion alarm|

Medical alarm|
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:

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 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 0 in the Ajax app and click Add Device.
   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 depend on the ping time defined in Jeweller settings. The default value is 36 seconds.

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.

If the detector or device requires a 12 V power supply for operation, it can be connected to the power terminals of the corresponding MultiTransmitter zone. Separate terminals are provided for fire 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 0
2. Select MultiTransmitter in the device list.

Tests are available in the device settings menu (Ajax app. Devices. MultiTransmitter. Settings :

• Jeweler 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-floor 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 Illll least, relocate the device as repositioning even by 20 cm can significantly improve the signal reception.

If the 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.

1. Secure the body to the surface with bundled screws using at least two fixing points. In order for the integration module tamper to respond to a dismantling attempt, be sure to fix 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 Mt 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 x 64 x 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.

is suitable for equipment care. Do not use any substances containing alcohol, acetone, gasoline, and other active solvents to clean the device.

After the normal state of the terminals is resumed, you will receive respective notification
Lost contact. /device name/ In /room name/| The connected wired detector is torn off.
Notification can be obtained If an EOL NO connection Is used| Check the connection of the wired device or detector to the integration module

Fire alarms reset

In the case of alarms of the fire detectors connected to MultiTransmitter, the window prompting of the need to reset the alarms is displayed in the Ajax app. This will make the detectors return to their normal state and continue to respond to a fire.

If the detectors are not reset after the fire alarm, they will not respond to the next fire, as they will remain in alarm mode.

There are two ways to reset fire detectors:
1. By clicking the button in the notification in the app.
