The Hochiki FIRElink-25 is a single-pipe aspirating (air sampling) smoke detector that gives very high sensitivity smoke detection in a small package. Hochiki positions it as the entry-level FIRElink unit for smaller areas up to 250 m², such as small server rooms or retail spaces.
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
