Aviation Low-intensity obstruction lights

 ZOM-1-AL >10cd, ICAO type A

30-265V AC/DC, IP65.

The low intensity obstruction lights ZOM-1-AL are an innovation solution on the market of aviation light-signal equipment designed for high objects light obstruction, which we offered in 2015, and implemented in an aluminum body with the DOW optical polycarbonate light filter (Switzerland), equipped with Fresnel lens.

The obstruction lights have been developed using our 10-year production experience and case studies of the best experts of the country in the field of light engineering, construction and electrical engineering. We have set up the target to provide a customer with the most efficient solution in terms of the innovative and reliable equipment which should meet all expectations and needs. Quality control at all production and supply stages enables to prevent any claims.

Function objective:

The aviation obstruction lights ZOM-AL are produced according to 27.40.39-004-28320930-2018 specifications and are intended for light-marking of high objects (obstructions) which pose dangers for air transport (high residential and office buildings, stacks, cooling towers, relay mobile communication masts, tele-radio towers, tower cranes, water towers, bridge pylons, power transmission towers, wind turbines, lighting masts, any buildings in the vicinity of airfields).

The lights are light-signal devices of red steady, which completely comply with ICAO classification for the low intensity obstruction lights, type A, which are mounted on high stationary objects 45m high (ICAO).

    complex as well as each obstruction light separately);

    Status monitoring system contains galvanically isolated, normally-closed contacts allowing

    seamless integration into any remote monitoring system;

    Long maintenance intervals;

    Supply power voltage variations do not affect to light output;

    Very low total lifetime costs;

    Lightweight and small low wind load factor.

Design advantages:


     A wide range of power voltage enables to switch the obstruction lights ZOM-1-AL with both AC and

    DC power source irrespective of polarities.

     The inbuilt monitoring status system enables to control performance of not only the whole

    obstruction lights set, but also each separate light remotely.

     The monitoring status system contains galvanically isolated normally-closed contacts, which allows

    getting it integrated into any remote monitoring structure. 

None of LED light source used in obstruction lights, which is available on the market, does not have the complete list of advantages implemented in the obstruction lights of ZOM line. 

Complete set:


1. The obstruction light (a body of light equipment)         1 item

2. Stationary LED module                                              1 item

3. Manual                                                                     1 item


Build types:

Main mounting and operation requirements:

The obstruction lights ZOM-1-AL are mounted by a holder (a base stand) with outer G ¾ thread. The mounting base stand are installed on top of high objects (roofs, etc.), subject to light obstruction.

A stationary LED module is a light source which does not require any service and replacement for the entire period of its operation.

So as to connect power and monitoring cables, you should unscrew the top optical unit of the obstruction light from its base, then unscrew the stationary LED module from the obstruction light base. Afterwards, screw the device base on the base stand, next connect the cables and assemble the device. While assembling it, make sure that the rubber seal is tightly seated. After connecting the cables to power and monitoring terminals, before screwing the device on a base stand, turn it anticlockwise to interweave the cables in the opposite direction. Finally, screw the obstruction light on the base stand tightly without making extra efforts. Cables interweaving made before will be eliminated.

You should brush the optical unit with clean cotton, soft flannel or suede leather without using any solvent or grinding materials, if it gets dirty. Afterwards, you should clean with spirits-soaked cotton. 

Mounting options:



The obstruction lights packaging according to GOST 23216 (All-Union State Standard) for storage conditions 2 (s) GOST 15150 (All-Union State Standard). The lights ZOM-1-AL are packed in a shipping container, which secures safety and protection from mechanical damage and atmospheric precipitation. 


Labor safety rules:

To provide safety operating the obstruction light, it is prohibited:

  To replace the stationary LED module of the obstruction light ZOM-1-AL for the light source with

    lower light intensity value;

  To carry out any operations with the obstruction lights with power on;

  To assemble or operate the obstruction light with damaged insulation;

  To assemble and operate the obstruction lights, it is required to follow PUE (Electrical Equipment


Data about claims: 

The claims are made to the supplier in case any defects and malfunctions can be found which lead to the obstruction lights breakdown before warranty period expires.

You should state in the claim report:

The obstruction light type, defects and malfunctions, conditions under which they were found, the operation time of the device. The copy of the payment document for the device must be attached to the report.
