Product Description
The ASR1102A(V2) is an RS-485 fingerprint and RFID reader for access control installs where card-only entry isn't enough.
Key specs
- Interface: RS-485 protocol
- Card type: IC (Mifare) by default; "-D" variant reads ID EM cards
- Credentials supported: card, fingerprint
- Fingerprint capacity: up to 3,000 templates
- Display/feedback: blue backlight, beep, LED indicator
- Reliability: watchdog function to keep the device free from halting
- Mounting: surface mounted
Fitting notes
RS-485 keeps wiring consistent with other Dahua access control gear on the same bus, which matters when you're speccing a multi-door job and want a single comms protocol across readers. The default model reads Mifare 13.56MHz cards; if the site uses EM/ID cards instead, specify the ASR1102A-D(V2) variant rather than the standard unit.
The 3,000-fingerprint capacity is worth flagging on larger sites — staff turnover and re-enrolment eat into that figure faster than card-only databases, so check headroom before committing to fingerprint as the primary credential on high-occupancy doors.
Surface mounting keeps installation straightforward on solid walls or frames; there's no flush-mount spec given here, so plan enclosures accordingly.
