MultiRelay Fibra
Manufacturer overview
Four-channel relay with potential-free contacts to control power supply remotely
Advanced automation for greater safety. Superior MultiRelay Fibra is a relay module designed to implement complex wiring diagrams. It has four relays with potential-free (dry) contacts that can control four separate circuits independently. MultiRelay can integrate various appliances, electrical mechanisms and even third-party security devices into the Ajax system. With Ajax scenarios, the module provides fully automated actions in response to alarms and security mode changes or performs them by a specified schedule.
Smart security and comfort. Use automation scenarios to make life safer and more comfortable. Set your office lights to turn off automatically on arming. Program your projectors to turn on when outdoor motion detectors identify intruders. Or turn on your toaster at a certain time in the morning.
5 automation elements with MultiRelay. The module has four relays that can control four separate circuits independently, meaning it can maintain four different appliances or electric mechanisms. Automation scenarios can be configured for each relay separately. Also, several relays can be connected to control one device if required by the wiring scheme.
One multi-purpose casing. The convenience for PROs is a big priority, so Ajax products are always thought out to every detail, hence easy to work with. That’s why we created Case, a one-stop casing suitable for module-type Fibra devices. Various size options facilitate combining multiple modules, optimizing space and reducing installation expenses. MultiRelay is compatible with Case 2 and can be installed in a single casing with other devices.
Unique wired technology. Fibra is proprietary Ajax technology for secure two-way communication between devices and a hub or module that extends the Fibra line. Fibra features encryption and device authentication to prevent sabotage, spoofing, and data theft. The Fibra line supports all types of devices, including sirens, keypads, and detectors with photo verification.
Energy efficiency as a priority. Fibra communication requires minimum power consumption: the module consumes only up to 0.18 W at its peak. Fibra also follows the TDMA principle. Each device has a short time frame to exchange data with a hub, and its communication module is inactive the rest of the time. This significantly reduces power consumption and helps avoid interferences even when multiple devices communicate simultaneously.
