The D1x represents a continuously evolving family of certified notification, initiation, and detection products engineered for operation in the most demanding hazardous industrial and harsh marine environments. Combining extensive international certification with advanced electronic design and robust marine-grade aluminium enclosures to deliver hi-performance signaling and detection solutions. D1x devices are approved for use in Class I/II Division 1 locations to UL/cUL, as well as Zone 1 applications to ATEX/IECEx. Selected variants additionally carry UL1638, CAN/ULC-S526, EN54-23, and UL Marine approvals, enabling deployment across a range of harsh industrial, offshore, and maritime applications.
Integrated audible and visual notifications
The D1xC1 and D1xC2 ranges combine hi-intensity audible and visual signaling in a single, factory-configured device, simplifying installation while maximising alarm effectiveness. Xenon strobe beacons are paired with either flare horn sounders or compact radial horns, the latter providing omni-directional sound coverage regardless of mounting orientation.
Strobe options include 5 and 10 Joules outputs delivering up to 1,000,000 Candelas in seven UV-stable, field-replaceable colours, while sound output reaches up to 123 dB(A) for hi-noise environments. Selected 24Vdc variants are approved for fire alarm applications. A threaded flame path, compact internal layout, and ratchet-adjustable stainless steel brackets improve serviceability, wiring access, and installation accuracy.
The D1xC1F series extends the range to fully certified explosion-proof public mode fire alarm solutions for Class I Division 1/2 and Zone 1 to UL/cUL installations. It includes 15W and 25W loudspeakers with 25/70V line transformers or hi-output alarm horns, combined with Xenon strobes up to 190 Candelas, with automatic synchronisation as standard.
Alarm horn sounders and loudspeakers
Standalone D1xS alarm horn sounders are available in flare and radial formats, supporting up to 64 selectable first-stage alarm tones via internal DIP switching. Remote triggering enables up to four alarm stages or channels. The D1xS1 24Vdc variants carry approvals for public mode fire alarm systems.
The D1xL loudspeaker range includes 15W and 25W models with low-impedance and 70V line capability. DNV type approval confirms suitability for offshore PAGA and fire voice systems. High Q-factor drivers, controlled directivity, and factory-fitted transformers ensure excellent speech intelligibility in hi-ambient noise and corrosive marine conditions.
Manual call points, beacons and heat detectors
The D1xCP1-PS explosion-proof manual call point is UL and UL Marine listed, SIL2 compliant, and rated NEMA 4X, providing dependable manual initiation in hazardous and corrosive environments. The D1xB2 Xenon beacons deliver outputs of 5, 10, 15 or 21 Joules with peak light output of 2,100,000 Candelas. With LED beacon providing an alternative for low-power applications.
The D1xH1 heat detector range integrates Detect-A-Fire® rate-compensated sensing technology within the marine-grade aluminium enclosures. Approved to UL, cUL, ATEX, and IECEx, and SIL2 compliant to IEC 61508, these detectors provide reliable fire and over-temperature detection across, and Class I/II Divisions 1 and 2 to UL, and Zones 0 and 1 to ATEX/IECEx.
D1x family - a reference standard for harsh signaling specifiers
By combining hi-output performance, global approvals, and rugged marine-grade enclosure, the D1x family establishes a benchmark for hazardous-area signaling. From notification and voice evacuation to initiation and detection, it provides a scalable, compliant, and dependable safety platform for harsh and critical industrial applications where life-safety and operational continuity are paramount.
