Flood-prevention system
Set the automatic water shut off in case the washing machine breaks or a pipe bursts. Control the water supply at the facility remotely or set up a schedule.
Automatic gates / barrier
Control opening-closing via the app or using Button. No compromises in comfort and safety.
Electric lock
Lock or unlock doors with the app or Button. Block access to premises by alarm or Night Mode activation and sleep calmly.
Security smoke cannon
Set up the smoke cannon triggered by any detector alarm or DoubleButton hold-up device activation. Such a system reliably shelters people and valuables from burglars.
Roller blinds / motorized curtains
Control the equipment remotely through the app, via Button, or set a scenario: when changing the security mode, according to the time of day, or by alarm activation.
ACS blocking
Set up Access Control System (ACS) reader blocking when arming the system to prevent employee access to the guarded premises and avoid false alarms.
Features
Flexibility at the core
Settings versatility and low power consumption make Relay a universal tool for equipment control. Dry contact is not galvanically connected to the device power supply so that it can be used both in low-voltage and household networks. There are bistable and pulse modes. The relay can be easily connected to a power supply unit paired with a backup battery.
- Pulse 0.5–255 seconds
- Power supply 7–24 V DC
- Dry contact
Installation
No extra effort
Connecting Relay to the hub takes less than a minute — it's enough to scan a QR code with the Ajax app. The miniature device (39×33×18 mm) fits easily into a junction box, an electrical panel, or a switching unit body. And the flexible external antenna provides stable connectivity.
Jeweller
Always in touch
We developed the Jeweller radio protocol to ensure uninterrupted interaction of all security system devices. The radio protocol uses frames to synchronize device communication, authentication to prevent forgery, and encryption to protect against hacking.
- Two-way communication at a distance of up to 1000 meters
- 5 ReX radio signal range extenders in the system
