New D1xB2 explosion-proof SIL 2 warning signals
E2S Warning Signals introduce latest additions to the D1x family of warning beacons
THE latest additions to E2S Warning Signals’ D1x family are the new D1xB2 beacons, which offer global approvals with SIL1 and SIL 2 compliance and are available as either Xenon or LED.
Strobes are offered in five-, 10-, 15- or 21-Joule Xenon variants with four flash rate options and are approved for private mode fire alarm use to UL1638. The high-power LED array features a steady mode for status applications, five flash patterns and three remotely selectable alarm stages/channels.
The beacons are UL/cUL and ULC approved for use in Class I/II Division 1, Zone 1 and Zone 21 explosion-proof environments and IECEx and ATEX certified for Zone 1 and 21 applications.
UV-stable polycarbonate lens filters, protected by a stainless-steel guard, are available in amber, blue, clear, green, magenta, red and yellow. The lens design enhances the light output and is field replaceable, allowing beacons to be repurposed on site.
Low inrush and operating current allow more units to be installed per circuit, simplifying system design and reducing cost, and all beacons on the same circuit are automatically synchronized.
For installations requiring signals compliant to UL1971 for public mode fire alarm installation, as emergency signalling devices for the hearing impaired, the D1xB2XH1 and D1xB2XH2 provide the brightest, auto-synchronizing, solution available.
All variants employ an innovative enclosure with multiple cable entries (two x 3/4in NPT and two x M20 side entries and one x 3/4in NPT pendant entry). A threaded flame path allows quick installation and simplifies maintenance inspection, whilst the large termination area maximizes cabling space.
The lightweight, corrosion-resistant, marine-grade aluminium enclosure can be either conduit or surface mounted, utilizing the built-in mounting lugs. An optional stainless-steel mounting bracket is available, providing fully adjustable positioning in any direction for optimum effectiveness.
In addition to the stand-alone beacons, the D1x family includes combination units that provide sound outputs up to 116dB(A) with 64 user-selectable alarm tones and four remotely selectable stages/channels to support audible signalling of multiple scenarios from a single device. The integrated Xenon beacon can be linked internally to the alarm horn to minimize cabling requirements and installation time, and the alarm horn and strobe can be initiated simultaneously or independently.
