Sektoria-M250 series
The simplified single-flank wirewave detector series is designed for perimeter sections up to 250 meters long and features automatic learning for quick and convenient setup. The detection zone is formed between two parallel wires and can reach a height of up to 2 meters. This series is ideal for areas with complex terrain, frequent curves, and irregular layouts, providing stable performance and durable protection. During setup, one operator simulates different intrusion scenarios, while another activates the learning function at the moment of crossing. The detector records each scenario in its memory for subsequent detection.
Sektoria-M250 – the standard modification of the series features a compact metal housing with IP65 protection and provides reliable intrusion detection with standard interference immunity. Alarm output is provided via a dry-contact relay.
Sektoria-M250S – the enhanced-protection modification, featuring improved electronic components, multilayer PCB protection with specialized compounds, increased protection against moisture and dust, and an extended operating temperature range of –60 to +85 °C. A two-level protection system safeguards the electronics against increased voltages induced by lightning discharges. Built with corrosion-resistant metal components, it retains a compact design. Alarm output is provided via a dry-contact relay.
Sektoria-M250+B – the standard modification of the series, supplied with a junction box providing lightning protection for all connected lines.

Sektoria-M250
General Information
Sektoria-M250 is the simplified version of the single-flank wirewave intrusion detector series, suitable for most applications requiring perimeter protection up to 250 meters in length. It is ideal for areas where dual-position microwave detectors cannot be deployed due to complex terrain, numerous perimeter bends, or other installation challenges. The detector features automatic learning of intrusion scenarios for quick and convenient setup and provides a single alarm output channel via a dry-contact relay.
Built with reliable electronic components, the detector provides stable operation and effective signal processing with good immunity to interference. The detector generates an alarm not only in case of intrusion, but also in the event of power loss, open or short circuit of the detection cables, tampering with adjustment controls, or opening of the adjustment unit cover.
The enclosure of this modification is made of stainless steel and aluminum, providing high corrosion resistance. Its IP65 protection rating minimizes the effects of external conditions, allowing decades of stable operation even in harsh climates with temperatures ranging from –50 to +50 °C. Compact dimensions further simplify transportation and installation.
Installation guidelines
For perimeter sections up to 250 meters in length, the detector ensures continuous intrusion detection along the protected boundary, with a detection zone height of up to 2 meters. The detection zone is formed by two parallel wires, with its primary active area located between them. The wires are secured using mounting brackets of appropriate lengths, specifically designed for our wirewave detectors and various installation configurations. We recommend the following installation options:
• Installation along the top of a fence
This configuration is recommended when the fence structure is sufficiently robust and cannot be damaged or bypassed without entering the detection zone, including attempts such as tunneling beneath the fence. This method is particularly suitable for concrete fences. Short mounting brackets are used for this installation option.
• Protection of vulnerable fences
In this configuration, the detection zone extends from ground level up to approximately 1.5 meters in height, using medium-length mounting brackets. This arrangement prevents undetected intrusion both through fence damage or shallow tunneling, as well as attempts to climb over the fence or jump across the detection zone. This installation method is recommended for mesh, sheet metal, brick, wooden, and other mechanically vulnerable fence types.
• Open-Area Perimeter Protection
In the absence of any physical barriers, full perimeter control can be achieved using long mounting brackets, forming a detection zone up to 2 meters in height. This configuration reliably prevents undetected crossing of the protected area under real-world intrusion conditions.
Detector setup
Detector setup is performed using the automatic learning function, ensuring quick and convenient configuration for the required detection task:
• Intrusion scenario simulation allows one operator to simulate different intrusion scenarios by crossing the detection zone in various ways.
• Scenario recording is activated by another operator at the moment of crossing, allowing the detector to record each simulated scenario in its memory for subsequent detection.
