Hochiki FIRElink 4 Pipe Aspirating Smoke Detector with Command Module (FIRELINK-400CM)

The Hochiki FIRElink-400CM is the four-pipe FIRElink-400 aspirating smoke detector with an integrated Command Module. It gives very high sensitivity smoke detection with built-in immunity to dust and dirt build-up, for large areas such as warehouses and factories.

The Command Module provides a single place to display, control and interface a network of up to 127 FIRElink detectors, and allows global programming of all detector functions at once. All FIRElink detectors are LPCB approved to EN54-20:2006 Classes A, B and C.

Key features

• Integrated Command Module controls, programs and tests other FIRElink units on the same network
• Four sampling pipes, up to 200 m aggregate (still air)
• Laser-based forward light scatter for reliable early warning
• Unique dust discrimination to reduce false alarms
• RS485 communications for networking and remote communications
