BA386 I.S. LED Flashing Beacon

Intrinsically safe
FM and ATEX certification
Choice of five colors
Two double flashes per second
IP56 environmental rating
Compatible with a wide range of barriers

The BA386 provides a bright flashing warning signal in a plant or processing area where ambient noise levels may drown out an audible alarm. It is significantly less expensive than traditional Xenon devices, yet has a similar light output and flashes more rapidly – making it more immediately noticable. Available in five colors to enable multi-stage alarm level protocols. Factory Mutual and ATEX intrinsic safety certification enable it to be used in virtually any classified hazardous location. Ask us about suitable intrinsic safety barriers.

DA135 I.S. LED Flashing Beacons

Intrinsically safe
ATEX II 1 G EEx ia IIC T6
Choice of five colors
Single, dual, or triple flash modes
Dual color option
IP65 environmental rating
May be combined with sounder and pushbutton
Isolated control connections
Compatible with a wide range of barriers
Pipe or wall mounting

DA135 beacons offer multiple alarm modes to provide visual warnings in a variety of situations. A choice of five bright colors – including blue and white - plus single, dual and triple flash cycles. There's even a dual color option to warn operators of a relative change in status. Protective lenses appear clear until the LEDs are illuminated. Each beacon may be connected to a sounder and acknowledge/reset pushbutton to create a local alarm station. The electronics are totally encapsulated, and wiring connections are made in a separate terminal chamber. All control connections are fully isolated to simplify circuit design. Ask us about suitable intrinsic safety barriers and isolators.

LN870 I.S. LED Stack Lights

Intrinsically safe
ATEX II 2 G EEx ia IIC T4
Available in five bright colors
Reliable LED illumination
10+ year continuous life expectancy
Low current consumption
Built-in vibration shock absorber
Surface or pole mounting
Compatible with a wide range of barriers
No explosion-proof housing required

Multi-color signalling comes to hazardous locations in the form of the LN870 light tower. Bright LEDS enable this design to be certified as intrinsically safe when used with the appropriate safety barriers — ask us about economical multi-channel isolating intrinsic safety barriers. Up to five lamp segments can be stacked and there are five different colors to choose from.

BA390 Series I.S. LED Cluster Lamps

Intrinsically safe to FM and ATEX
Available in five bright colors
Reliable LED illumination
10+ year continuous life expectancy
Low 20mA current consumption
Super low 4mA versions for fieldbus
IP65 environmental rating
Panel mounting
Compatible with a wide range of barriers
No explosion-proof housing required

A bright and uniform light output is insured by the colored diffuser and current regulator incorporated into these lamps. Specify Model 390S for fieldbus applications. Ask us about economical multi-channel galvanically isolated intrinsic safety barriers that make for simple, cost-effective installations.

There's no need to debate the issue of whether LED's meet the definition of "simple apparatus" because these LED cluster lamps have both Factory Mutual approval and ATEX certification as intrinsically safe devices.

DA180 Series I.S. LED Cluster Lamps

Intrinsically safe
ATEX II 2 G EEx ia IIC T4
Available in six bright colors
Reliable LED illumination
100,000 hour life expectancy
Low 20mA current consumption
Giant 2.6" / 66mm diameter lens
IP65 environmental rating
Panel mounting
Compatible with a wide range of barriers
No explosion-proof housing required

For high visibility indication both at a distance and from the side the DA180 Series of giant LED cluster lamps are hard to beat. A choice of six equally bright colors enable sophisticated alarm or status signalling schemes to be implemented in hazardous classified locations. Internal regulators limit current consumption to 20mA and make it easy to match these unique lamps to a wide choice of intrinsic safety barriers and isolators. Simple single-hole panel mounting with a rubber gasket achieves IP65 environmental protection. Tough polycarbonate lenses resist impact damage.

BEXBG05D Flashing Beacon

Flameproof
ATEX EEx d IIC T6 Certification
Available in six colors
Xenon light source
Bright 5 joule output.
24VDC, 115VAC & 230VAC versions
Auto synchronized 1Hz flash
IP67 environmental rating
Mounting bracket included

NEW! — now comes with a stainless steel lens guard

If an ATEX EEx 'd' electrical installation is acceptable the BExBG05D will provide a highly visible warning beacon to augment audible alarms in noisy environments. An alternative stainless steel pipe mounting kit is available. In the case of 24VDC powered units an end-of-line resistor or diode may be installed inside the beacon enclosure for line monitoring purposes. Ask about even brighter 10 and 15 joule versions.
