Access  Control Hardware


The XSR is Impro Technologies’ third generation remote relay device comprising of a relay, and two sensor inputs.
The propriety S-Bus communication protocol allows bidirectional communication using 128 bit AES encrypted protocol over a distance of up to 150 metres between the host and the relay box.
Suitable for use in high-end as well as budget applications, the XSR may be connected (via SBus) to the ImproX Biometric Multi-discipline Time Attendance Reader (BMTA) – or to the entry-level UniScan and FlexiScan Controllers.
Note that the XSR’s Door Open Sensing feature is not available when controlled by the entry-level UniScan and FlexiScan Controllers.
