Ajax MultiTransmitter White
Manufacturer overview
Wireless module to integrate up to 18 third-party devices into an Ajax system
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 It is a common situation when your system is still capable of protecting your property but is clearly outdated.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, keypads, 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. Rails for fixing the backup battery 4 or 7 Ah 1
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. Numerous event types are available: intrusion, fire, auxiliary alarm, panic button, gas alarm, malfunction, leakage, etc.
