Photo of Beka Model BA386 intrinsically safe flashing LED alarm beacon

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
Can power BR385 sounder with same safety barrier

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.

Can be used in conjunction with a BR385 alarm sounder using a single galvanically isolated barrier. The BA386 beacon includes terminals to power the sounder, and for an external push button to silence the sounder. The silence time is adjustable from 1 to 30 minutes. We can even supply a kit to combine the two units.

Recommended Barriers	Beacon powered alone	D1042Q (Use one of four available channels)

Photo of RTK Model DA135 intrinsically safe flashing LED alarm beacon

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.

Recommended Barrier	Beacon w/wo Sounder	D1042Q (Use one of four available channels)
