The corridor and the lane
answer to one log.
Turnstile credentialing, face gates and door controllers on one TCP/IP + RS485 bus — a person's movement through the building becomes one auditable record, not three vendor exports.
Lining a corridor
Channel map
Entry lane, corridor doors, lift and plant gates — each surface gets a credential class.
Lane reader
Industry-grade BFM980A module inside the turnstile head, hands-free at the pause point.
Bus wiring
TCP/IP + RS485 between controllers; the 12 V 5 A rail feeds cabinet and locks.
One roster
Enroll once — the roster mirrors to lane, door and lift via the free SDK; every pass is a record.
Two surfaces, one decision layer.
Lane and door differ in mechanics, not in identity. Both read against the same roster, both decide on local controllers, and both append to the same audit stream — so a shift anomaly reads as a route, not as two databases.
- Turnstile class — BFM980A's industry-grade sensing survives the dust and moisture of a corridor head.
- Throughput doors — face terminals carry the 62% face-first majority at 0.3 s without touching the lane mechanics.
- Campus scale — TM-SS02/SS04 step the same stack from two doors to four-door sites without a firmware change.
Channel component table
| Surface | Recommended class | Role | Key values |
|---|---|---|---|
| Turnstile head | BFM980A module | Industry-grade fingerprint at the lane | Rugged sensing · company lab 99.99% fake-finger rejection class |
| Entry gate | TM-Ai06 / TM-Ai18E | Face throughput above the lane | 0.3 s · 5,000-user tier · TCP/IP |
| Corridor door | TFS50 / TFS800 | Fingerprint + card combi | 1,000 templates · 100K+ cards · RS485 |
| Lift call | TM-AI318F | AI face lift-control panel | Floor authorization · same event log |
| Controller | TM-SS01 / TM-SS02 / TM-SS04 | Local decision and storage | 10,000 users / 50,000 records · TCP/IP+RS485 |
| Rail | TM-JX | Cabinet supply | 12 V 5 A |
The bus is one cable plant; the roster is one campaign. Night rounds can share the same log through the S205D/S208LED guard-tour readers.
Three loads on the bus
Lane reader
Industry sensing at the pause point — the part a turnstile builder ships with.
Gate reader
Face throughput at 0.3 s for the lobby route — where the queue is the complaint.
Decision layer
TM-SS controllers — 10,000 users, 50,000 records, one event stream.
Channel FAQs
The BFM980A industry-grade fingerprint module is the lane class; face terminals serve high-throughput entrances above the lane.
Yes — every lane pass and door event reports over the same TCP/IP+RS485 bus into one audit trail.
Controllers decide locally against 10,000 users / 50,000 records; lanes keep serving on the stored roster with events queued.
One lane and one door — the whole pitch.
Sample a BFM980A with a TM-SS01 and an 18E face unit; the corridor sells itself from two samples.
