AAWSs  - 'Active Advance Warning Signs'

Flashing beacon units to make 'passive' signs 'active'. 

AAWSs are primarily designed to deliver advance warnings to drivers approaching a danger point, advising them to slow down and stop; or modify their behaviour in some other way.

When deployed in advance of a railway crossing (eg 300-400 metres before), they fulfill the requirements of an active RX-11 type sign.

AAWSs not only designed to be more easily seen than passive (ie unlit) signs, they're designed to be more easily deployed and at a lower cost than other active systems. Whether as part of a new installation, or as an upgrade to existing passive (unlit) warning sign installation, AAWSs deliver wireless connectivity and wireless control to a multitude of applications.

When used as part of a road singallign treatment, they're generally supplied as mated pairs, comprising:

• a wireless control unit
• bright flashing LED beacon unit with a pair of LED lights
• a solar charging system and rechargeable lead acid gel batteries

Activation:

• by a wireless ADC as part of a larger warning network (eg railway crossing warning system)
• directly by a wireless detection radar, or other automated device such as a pedestrian pressure mats, inrfa-red beams, etc

Typical applications:

• in advance of a railway  level  crossing, as an 'Active RX-11' type sign
• at a railway level crossing, as an 'Active RX-5' type sign 
• on the approaches to a pedestrian crossing (alone or as part of a PANDA Crossing system) 
• on the approaches to road 'black spots'
• at vehicle entries/exits
• on temporary work sites (eg to warn pedestrians of trucks entering a site workshop)
