The U2-HS is a modern two-channel remote control set featuring a compact superheterodyne receiver (U2HR) and two DWB100HT key fob transmitters. This set is designed for secure and reliable remote control of alarm systems, access control, and automation devices. The system uses a dynamic code (KEELOQ® algorithm) for enhanced signal security and complies with the latest EU standards for SRD (Short Range Devices).
The U2HR receiver offers excellent sensitivity and selectivity, a significantly extended operating range (up to 300 meters in open space with DWB100HT key fobs), and a much smaller size compared to previous models. It also introduces several new, highly useful features for flexible operation.

Flexible Button Assignment
Any key fob button can be assigned to any receiver output, enabling advanced configurations such as:
- Some one-button key fobs control output 1, others control output 2.
- One button activates both outputs simultaneously.
- One button turns an output ON, another turns it OFF.
- Any button on a four-channel key fob (CH4HT) can control output 1 or 2 independently.
Output Operation Modes
The receiver supports multiple output modes, including:
- Monostable: Output is ON for a programmed time; repeated presses extend the time.
- Bistable: Button toggles output ON/OFF.
- Monostable with early OFF: Output is ON for a programmed time but can be turned OFF early.
- Interlock: Only one output can be ON at a time.
- Hold: Output is ON as long as the button is pressed.
- Separate ON/OFF: One button turns output ON, another turns it OFF.
LED Indication
Two LEDs indicate output status: Output 1 (green for ON, red for OFF), Output 2 (green for ON, off for OFF).
Signalling Output S
Open Collector output S (1A/60V max) for external siren, buzzer, or strobe connection.
Transmitter Memory
The receiver can store up to 104 dynamic code transmitters (20 in some modes).
