BDH160 and BDH260 by INIM: Intelligent Linear Smoke Detectors for Large Areas

In the fire detection industry, protecting large and complex environments requires reliable, accurate, and easy-to-manage solutions. The new BDH160 and BDH260 by INIM provide an advanced response to the safety needs of industrial warehouses, logistics hubs, shopping centers, sports halls, museums, airports, and large commercial or public buildings.Thanks to their self-aligning optical linear technology and intelligent signal management, these devices ensure high performance over long distances while reducing installation time and maintenance costs.

Self-Aligning Optical Linear Technology

The BDH series detectors use infrared transreflective technology: the device emits an IR beam toward a reflector, which sends the signal back to the receiving head. By analyzing the beam intensity, the system can detect the presence of smoke along the optical path.One of the most innovative features is the motorized self-aligning head, capable of:

• automatically aligning during installation;

• compensating for structural movements over time;

• maintaining maximum operational reliability;

• reducing manual maintenance interventions.

This technology makes the detectors particularly suitable for environments exposed to vibrations, thermal expansion, or structural movement over time.

BDH160: Reliable Linear Detection up to 160 Meters

The BDH160 is a self-aligning optical linear smoke detector designed for professional long-distance applications.The system consists of:

• a detector head with IR transmitter/receiver;

• a ground-level control unit;

• reflectors for signal return.

The standard range covers distances from 5 to 70 meters, but thanks to dedicated expansion kits it can reach up to 160 meters, making it ideal for large industrial or commercial spaces.Key advantages of the BDH160 include:

• simplified installation thanks to self-alignment;

• high detection accuracy;

• reduced false alarms;

• easier maintenance;

• integration with INIM systems through the

  EU311

  module;

• loop-powered or separate power supply options;

• support for up to 20 detectors per loop (subject to software verification).

BDH260: Smart Management via Bluetooth and App

The BDH260 retains all the advanced technical features of the BDH160 while adding an especially useful function for installers and maintenance technicians: Bluetooth connectivity with smartphone app management.Through the free dedicated app, users can:

• monitor detector status;

• perform quick checks;

• simplify maintenance operations;

• access diagnostic information;

• speed up configuration procedures.

This smart management significantly reduces intervention times and improves the efficiency of routine maintenance activities.Like the BDH160, the BDH260:

• uses IR transreflective technology;

• features a motorized self-aligning head;

• supports distances up to 160 meters with dedicated kits;

• is compatible with INIM loops through the EU311 module;

• can be powered via loop or separate supply;

• supports up to 20 detectors per loop (subject to software calculation verification).
