Autronica BD-200 Heat Detector, Interactive Plug‑in Point Detector, Configurable Classes A1/A1R/A2S/B/C, 10–27 VDC — BDH-200 Head

Autronica BD-200 Heat Detector — Interactive Plug‑in Point Heat Detector (BDH-200)

Overview

• Manufacturer: Autronica Fire and Security AS
• Model: BD-200 (detector head 116-BDH-200)
• Type: Point heat detector (thermistor-based) for interactive fire detection systems
• Intended use: Dry-area heat detection where smoke detectors may give unwanted alarms (kitchens, galleys, bathrooms, boiler rooms, workshops, etc.)
• Standards: EN 54-5 / EN 54-17 (see manufacturer for full approvals and certificates)

Key features

• Interactive plug‑in detector head compatible with Autronica bases and interactive panels.
• Configurable alarm classes: A1, A1R (rate-of-rise), A2S (slow), B, C — selectable to suit the application environment.
• Thermistor temperature measurement provides temperature readout at the detector point.
• Built‑in short‑circuit isolator in each detector.
• Built‑in alarm LED; supports external LED output (requires specified varistor per datasheet).
• Automatic addressing for Autronica interactive systems.
• Proven technology, EMC compliant and designed to meet major maritime classification society requirements.
• Low susceptibility to dust, humidity, exhaust gases and electromagnetic disturbance.

Mechanical & electrical notes

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

Applications

• Ideal for environments prone to false smoke alarms (kitchens, galleys, boiler rooms, workshops). Suitable for industrial, maritime and offshore installations when used within an Autronica interactive fire detection system.
