Ajax Fibra MultiRelay
Ajax Fibra MultiRelay is a module to control electrical appliances’ power supply remotely. The device has four relays with electrically isolated dry contacts. The relays can control the power supply of electrical appliances connected to the circuit. To change the states of the relays, use the Ajax apps, create automation scenarios, or press Button.

| Communication
| Fibra communication technology Proprietary wired communication technology. Fibra combines the reliability of wires with the freedom of radio connection. Key features:
Connection to any point of the Fibra line MultiRelay can be installed behind the hub, detector, keypad, or siren.
Fibra line length up to 2,000 meters When using the U/UTP cat.5 twisted pair cable.
Encrypted communication
|
| Lines connection
| Number of input lines 1 MultiRelay can be installed behind any Fibra device.
Number of relays 4 Electrical appliances are connected to four relay outputs with dry contact.
Cable length up to 2,000 meters When using the U/UTP cat.5 twisted pair cable.
Maximum current up to 5 A at 30 V⎓ Maximum resistive load for each relay.
|
| Key features
| Temperature protection When one of the relays exceeds the permissible temperature, all closed contacts automatically open. The user receives an overheating notification.
Automation scenarios Adjusted in Ajax apps separately for each relay.
Relay modes bistable Adjusted in Ajax apps separately for each relay.
Operating time from 1 second to 2 hours Adjusted for pulse mode in Ajax apps separately for each relay.
State stability after power outage If the function is enabled, the current state of the relay contacts remains the same after a power outage.

| Recommendations
| For indoor use only. It is recommended to install it in Case that is sold separately and available in several options. |
| Sabotage protection
| Tamper alarm MultiRelay has a connector to fasten the tamper board to the module. The tamper board is in Case that is sold separately.
Protection against spoofing device authentication
Connection loss detection after 36 s Between the hub and MultiRelay. It can be changed in hub settings.
