Industry: Residential apartments
Country / region: United Kingdom (Belfast, Northern Ireland)
Model: RFID-4M barrier with PL-350 parking locks
System scope: One vehicle lane, 96 spaces for 84 apartments, resident tags, visitor release by intercom
Residents with an allocated space regularly found it occupied by an unallocated vehicle, and the management company had no enforcement route short of clamping.
Each allocated space was fitted with an induction parking lock and each resident was issued a tag bound to their own lock. The lane barrier reads the same tag, so the system knows which vehicle has entered and which locks it may release.
Space allocation is now self-enforcing and concierge calls about blocked bays fell by around 70 %. The management company no longer needs a clamping contract.
Test condition: 84 tags and 24 monitored locks, six months of operation, vehicles 0.9 to 2.6 t. Measured value: no false release and no lock jam recorded across the period. Benchmark: barrier-only schemes without a per-bay device leave 15 % to 30 % of bays incorrectly occupied in the same building class.
Binding the tag to the bay, rather than to the building, is what turns a barrier into an allocation system.
