D171 SPACE AGE

Product Overview

The Space Age Electronics D171 is an industrial-grade, explosion-proof 1IR+UV multi-spectrum optical flame detector designed to target hydrocarbon-based fires while maintaining total immunity against localized false alarm sources. Utilizing advanced digital signal processing (DSP) alongside a proprietary Convolution Method, the system continuously cross-examines incoming ultraviolet radiation against one discrete band of the infrared spectrum to pinpoint fire wavelengths at distances exceeding 100 feet. Housed in a NEMA 4X (IP66/IP67) watertight 316 stainless steel enclosure rated for Class I, Division 1 (Zone 1) hazardous settings, the D171 features an isolated field-wiring compartment and an array of hardwired relays, an analog 4-20 mA loop, and RS485 Modbus digital data pipes.

Key Features

• 1IR + UV Hydrocarbon Target Optics: Combines an ultraviolet sensor with a single discrete infrared band filter to isolate hydrocarbon fire signatures and reject false environmental ambient glare.
• Industrial Network Interfacing: Outfitted with Warning, Alarm, Fault, and Auxiliary dry contact relays alongside an analog 4-20 mA interface and an RS485 Modbus serial connection.
• Forensic Event Logging: Employs non-volatile FRAM memory to capture up to 200 sequential event logs and 6 multi-second FireGraphs® for detailed post-incident signature profiling.
• OptiRadar® Path Integrity Monitoring: Features an automated self-test framework that actively verifies internal electronic circuits and ensures the optical window path is clear of obstructive films, dirt, or ice.
• Rugged Enclosure & Thermal Resilience: Encased in an explosion-proof, investment-cast 316 stainless steel housing operational from −40∘F to +185∘F (−40∘C to +85∘C) with an optional internal condensation heater.
• Rigorous Life Safety Compliance: Manufactured in the USA, backed by a 5-year warranty, certified to meet SIL 2 dependability standards, and holds FM, CFM, CSFM, ATEX, and IECEx explosion-proof approvals.
