Low-intensity BA10 Light

Family : Obstacle warning lights
Category : Low intensity beacons

Application

The International Civil Aviation Organization (ICAO) has defined the specification for installation of Obstacle Warning Lights in the Annex 14 to the convention on international civil aviation, Volume 1
«Aerodrome design and operations» (July 1999).
The following structures are considered as obstacles to civil aviation:

• Factory chimneys

• Towers (Telecom, TV, …)

• High Voltage overhead cables

• Bridges

• High rise buildings

• Electrical power generation stations

• Cranes

The BA10 obstacle warning light is conforming the ICAO requirement thanks to its luminous intensity of more than 35 cd. The use of incandescent bulb offers benefits in terms of cost as well as disadvantages in term of life time (8 000 h) and power consumption (55W).

Installation

The low-intensity lights are installed on structures not exceeding 150 m high. Above 45 m, several levels of beaconing are required. The interval between two beacon levels must not exceed 45 m as well.
For factory chimneys, the obstacle warning lights must be installed from 1.5 m to 3 m maximum from the top of the structure. Three lights should be fixed regularly at 120° along the chimney circumference.
The BA10 obstacle warning lights are available either as a single unit or complete with a stainless steel mounting brackets as well as a connection box for power supply.
A photocell is also available upon request (option).
Depending on the obstacle location (above a take off climb surface for example), the ICAO requires uninterruptible beaconing in every circumstances ie. BBS system (master and slave) operating system.

Power supply and service continuity
The BA10 obstacle warning lights are delivered with 3 m cable for power supply.
The input voltage could be 12V, 110V-50Hz or 230V-50Hz upon requirement of the customers.
The BA10 lights are also available with a beacon failure alarm driving box (option).
A UPS cabinet with 12 h autonomy (0/ 20%) is available as well according to ICAO requirement for
uninterruptible beaconing in every circumstances
