Ajax - Module for integrating wired third-party devices into Ajax (Ajax Multitransmitter)

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.

The second life of an old wired alarm

We understand how difficult it is to decide on a wired alarm upgrade. It is a common situation when your system is still capable of protecting your property but is clearly outdated. Renovating with Ajax doesn't force you to leave behind the current equipment. It gives you a chance to build modern complex security based on existing wired equipment.

Security via smartphone

With MultiTransmitter, system users get security control via app, data-rich notifications, and automation scenarios. An installer can set up the system or device in the PRO-app, both while on-site and remotely.

More Ajax features

Perimeter IR detectors, household gas sensors, thermostats, float sensors, and other devices are ready to expand the Ajax areas of use. Connect them to a hub via MultiTransmitter and manage the combined security system in the Ajax app.

Multitasking in a single body

Less hassle with automated security

Use automation scenarios so that the security system instantly responds to threats without waiting for police. Ajax will be armed by schedule, turn on the light by the alarm of a motion detector, de-energize the room at the first sign of fire. With MultiTransmitter, an old alarm system becomes part of a safe and smart home.

Data-rich alarms

With MultiTransmitter, you can specify the type of alarm and a room for each wired device. This makes notifications more informative — you know not just what happened but where. This information is displayed using push notification, SMS, and is also sent to the security company's monitoring station under an appropriate code. A total of five types of alarms are available: intrusion, fire, medical assistance, panic button, gas leak.

Intrusion confirmation in 9 seconds

Connect MotionCam — a motion detector with a photo camera — to know for sure whether there are burglars in the place, or someone just did not disarm the alarm. The camera is activated only when the system is armed, and motion is detected. Contrary to video surveillance, the detector's photos are securely encrypted and transferred to the app in seconds, and only to those users who are granted viewing rights.

Radio communication without reliability compromises

MultiTransmitter communicates with a hub via an encrypted Jeweller radio protocol. This is a TDMA technology developed by Ajax Systems for uninterrupted communication with devices. Jeweller detects jamming attempts, switches to the backup frequency in case of interference, and allows Ajax wireless devices to run on battery power for years.

Security without barriers

When using ReX range extenders, Ajax security system's radio network can cover up to 35 km². But if some rooms are impermeable for radio waves, connecting wired devices via MultiTransmitter is the best solution. The length of wires can reach 400 meters.

Protected against sabotage

MultiTransmitter will inform you instantly if the connected devices have been interrupted with power failure, disconnection of the signal cable, or tampering. Electricity loss at the site will not be a problem either — the backup battery can provide power to devices for up to 4 days. MultiTransmitter body itself is equipped with two tampers that respond to removal of the integration module from the mount and removal of the lid.

• Instant connection loss detection with wired device (EOL)
• Cavity in the body for a backup battery 7 A⋅h
• 2 tampers that detect dismounting and opening of the body

Made by professionals for professionals

We made sure that the installation and setup process does not require any extra time or effort. Like other Ajax devices, MultiTransmitter connects to a hub in the app by scanning a QR-code. When connecting wired devices, you don't need to know the resistors' resistance values. The system will also warn you if a device was not connected correctly.
