The Hochiki FIRElink-100 is a two-pipe aspirating (air sampling) smoke detector that gives very high sensitivity smoke detection in a small package. Hochiki positions it as the mid-range FIRElink unit for areas up to 1000 m², such as offices, schools and medium-sized facilities.
It configures itself to the protected environment without complex set-up, and fits into a docking station that takes all sampling pipes and cables, so the detector can be fitted at final commissioning. Volt-free Fire 1 and Fault relays allow monitoring by a fire panel or BMS, and an optional FL-APIC card connects it to a Hochiki ESP addressable loop. All FIRElink detectors are LPCB approved to EN54-20:2006 Classes A, B and C.
Key features
- Ultra small, low cost aspirating smoke detector for discreet installation
- Laser-based forward light scatter for reliable early warning
- Two sampling pipes, up to 100 m aggregate (still air)
- Laser dust discrimination to reduce false alarms
- RS485 communications built in for networking and remote communications
- Docking station accepts pipes and cables before the detector is fitted
