UMA AIR-SR-4 – Wireless Receiver for Solar IR Beams – 4 Zones – 433 MHz

UMA AIR-SR-4 | 4-channel wireless receiver for infrared beam detectors

The UMA AIR-SR-4 is a wireless receiver with four input zones, designed to work with active infrared beam detector sets such as the UMA AIR-S60-2, AIR-S120-3 and AIR-S100-4. The receiver is a reliable solution for applications such as alarm systems, access control, smart home integration, intercom systems or linking alarm notifications to IP cameras.

Functionality
Each zone supports up to six paired detectors, allowing 24 detectors in total. The zones are configured via DIP switches. Wireless communication between the receiver and detectors uses 433 MHz FSK+FHSS technology for a stable, interference-free connection with a range of up to 1,000 m line of sight.

The receiver has four wired relay outputs (normally closed) for controlling external equipment. The unit is intended for indoor use and requires an external 12 V DC power supply (available as an option).
