5 automation elements with MultiRelay

4 separate circuits control

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.

Impulse and bistable modes

Each relay supports two operation modes:

Bistable — the relay changes contact state after each activation, turning the connected appliance on or off.
Pulse — the relay changes contact state for the adjustable time (from 10 s to 2 h).

The mode can be configured in Ajax apps for each relay separately.

Steady contact state

The device retains the current contact state of a relay. After a power loss and subsequent restoration, the contact state remains unchanged. The feature can be activated in Ajax apps for each relay separately.

Support for both AC and DC circuits

The module has relays with potential-free (dry) contacts and can control circuits with direct, alternating, or no current.

Configurable NC/NO contact states

Each relay supports two contact states:

Normally closed (NC) — the relay stops supplying power when activated and resumes when deactivated.
Normally open (NO) — the relay supplies power when activated and stops when deactivated.

The normal contact state can be configured in Ajax apps.

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 Case² and can be installed in a single casing with other devices.

Fibra

Unique wired technology

The Ajax system uses secure two-way communication based on the Fibra proprietary protocol. It features encryption and device authentication to prevent sabotage, spoofing, or data theft. Fibra lines are multifunctional and support connecting different types of devices to one line: 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.

TDMA and power-saving modes

Sabotage resistance

Tamper alarm³

MultiRelay needs to be installed into Case, which has a built-in tamper. The tamper notifies the security company and users about attempts to open Case or detach it from the surface.

Data encryption

All data the system stores and transmits is protected by a block cypher with a dynamic key. Encryption makes it extremely difficult to reprogram the device, replace or steal the data.

Regular polling

The device regularly exchanges data with the hub. The system controls each device state and reports if there is a malfunction or connection loss.

Protection against short circuit

The system instantly detects a short circuit on the line and notifies the security company and the users. And when the problem is fixed, there is no need to replace the fuses: the system will restore operation automatically.

Data-rich notifications

The Ajax system instantly notifies about alarms and events with informative notifications: security companies and users know exactly which device triggered, when and where it happened.

Device authentication against spoofing

The hub checks the device's unique parameters for authentication during each communication session. If any parameter fails the check, the hub ignores device commands.

PRO is king

The myth about wired systems being difficult to install is busted. Ajax minimized an expensive, long, and dusty experience for PROs by developing an ultimate set of tools to make the process easy and flexible, from project design to client support and system maintenance. The module is installed inside Case with only one move of the hand. Intuitive Ajax apps help quickly make the device a part of the system, and each device can always be reconfigured remotely without site visits. No need for programmers — everything is available out-of-box.

Fibra power supply calculator

The online tool provides security specialists with comprehensive information about the devices’ power consumption. It's easy to check before installation whether the wired system project will work in practice. The calculator allows real-time project-making, highlighting the problem areas and offering solutions. Once the calculations are finished, the results can be downloaded as a PDF file.

The module needs to be installed into Case. The installation kit includes all the necessary fasteners. The casing has holders for device placement which are flexible and require only one move of hand to install the module inside. A built-in spirit level and slightly bigger fixing points assist the professional in a perfectly accurate mounting position. Inside, Case has special fasteners for cable management and several perforated parts on the sides and back for wiring out cables. Markings for drill positioning and special protectors inside help to stop the drill before it hits holders or other components. The top lid of the casing is equipped with anti-falling screws to prevent accidental dropping of installation parts.
