Autronica BH-300 Optical Smoke Detector, Interactive with SelfVerify & Thermistor, 10–27 VDC — Point Detector (Pack of 1)

Autronica BH-300 Optical Smoke Detector — Interactive Fire Detection Point Detector

Overview

• Model: BH-300 (Autronica Fire and Security AS)
• Type: Photoelectric (light-scatter) point smoke detector with built‑in thermistor and SelfVerify function
• Intended use: Interactive fire detection systems for industrial, maritime, offshore and commercial installations
• Standards: EN 54-7 and EN 54-17 (see manufacturer for full approvals and certificates)

Key features

• Photoelectric light‑scatter detection for visible smoke particles.
• SelfVerify: automatic calibrated self-test every 24 hours to ensure correct alarm sensitivity and reduce maintenance.
• DYFI+ adaptive, self‑learning intelligence for improved detection performance in changing environments.
• Built‑in thermistor provides temperature readout at detector point.
• Short‑circuit isolator integrated in each detector.
• Built‑in alarm LED; supports external LED output (requires specified varistor per datasheet).
• Automatic addressing for Autronica interactive systems.
• Immune to electromagnetic disturbances; proven technology designed to meet major maritime classification society requirements.

Mechanical & electrical notes

• Detector head part number: 116-BHH-300; base: 116-BWA-100. Optional conduit boxes: 116-BWP-100/20 (M20) and 116-BWP-100/25 (M25). Optional audible indicator: 116-BBR-52 SmartBuzzer.
• LED/external indicator: connect LED between terminals 3 (+) and 4. When using the LED output or other equipment, install the specified varistor (Siemens SIOVS07K25, 39V — Autronica part no. 116-8464-003.5039) between terminals 1 and 4 in the base.
• Pinout (base): 1 = in, 2 = out, 3 = common (+ in, + out), 4 = external LED.

Applications

• Point smoke detection in clean (computer rooms), normal (offices, restaurants) and industrial (workshops) environments as part of Autronica interactive systems. Particularly suitable for demanding industrial, maritime and offshore applications due to adaptive intelligence and SelfVerify.
