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 It is a common situation when your system is still capable of protecting your property but is clearly outdated.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, switch off the potential cause of ignition 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 device name, 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 using an appropriate code. A total of 9 types of alarms are available: intrusion, fire alarm, medical help, panic button, gas alarm, leakage, tamper alarm, malfunction, custom (service event).

Jeweller
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 frequencies in case of interference, and allows Ajax wireless devices to run on battery power for years.
-
Connection to a hub at a distance of up to 2000 meters
-
Alarms delivered in 0.15 seconds
-
Adjustable ping from 12 seconds
Security without barriers
When using radio signal range extenders, Ajax security system's radio network can cover up to 35 km2. But if some rooms are impermeable to 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 short circuit, disconnection of the signal cable, or tampering alarm. 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 surface and removal of the lid.
-
Instant connection loss detection with wired device (EOL)
-
Free space in the body for a backup battery 7 Ah
-
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.
