The Sivananda CHECKMATE SM4F (KT ERP reference: KTI12003002SM4F) is an industrial single-zone walk-through door frame metal detector engineered specifically for metal detection and anti-theft screening. Constructed with a durable Fiber-Reinforced Plastic (FRP) archway and a space-efficient footprint of 840 mm x 610 mm, this system provides screening in high-traffic checkpoints, perimeter gates, and production exits across multiple industries.
Industrial Anti-Pilferage and Non-Ferrous Asset Protection
The CHECKMATE SM4F is engineered with specialized differential sensitivity designed to suppress ferrous interference while delivering enhanced sensitivity to non-ferrous metals such as copper and brass. This unique calibration profile makes it suited for manufacturing plants, smelting operations, foundry exits, electronics assembly lines, and electrical component factories where small copper wire coils, brass fittings, and non-ferrous tooling are susceptible to employee theft.
- Copper and Brass Screening: Detects concealed non-ferrous metals down to a 25 mm side cube to eliminate loss at worker egress points.
- Adjustable Thresholds: Plant security personnel can utilize the 9 preset sensitivity levels via a thumbwheel switch to balance screening stringency against regular clothing accessories.
- Self-Tuning Calibration: Auto Set Calibration requires no manual tuning after power-up, preventing calibration drift during shifts.
Transit Terminals and High-Throughput Passenger Screening
Pedestrian regulation is essential in mass transit environments like airports, railways, and bus stations. The CHECKMATE SM4F features an integrated Walk / Stop (Go / Stop) pacing indicator that paces oncoming passenger flow, reducing congestion and preventing tailgating through the 1920 mm (H) x 720 mm (W) passage corridor.
- Audio-Visual Feedback: Alarm triggering via dual audio buzzer, LED indicator, and visual bar graph alerting operators to detected items.
- Continuous Operation: Runs on standard 230 VAC ±10%, 50 Hz mains, with optional infrared sensors for counting pedestrian traffic and optional two-hour battery backup (they are not included) during transit power outages.
Government, Defense, and Embassy Perimeter Security
For high-security zones including defense sectors, embassies, government buildings, and police stations, the SM4F serves as a physical perimeter access checkpoint. Its plug-in type printed circuit board (PCB) architecture minimizes downtime, allowing fast field maintenance with standardized plug-in spare modules.
Corporate Offices, Institutional Gateways, and Public Venues
Corporate offices, worship places, auditoriums, clinics, and hospitals require reliable metal screening that handles continuous foot traffic without complex installation procedures. With detachable side panels and a detachable control unit, the unit supports rapid transport and installation in corporate lobbies and public gathering spaces.
| Deployment Environment | Target Material / Primary Threat | Key System Feature Utilized |
|---|---|---|
| Manufacturing & Assembly Plants | Non-ferrous raw materials (copper, brass) | Differential sensitivity, 25 mm cube detection |
| Railways, Airports & Bus Terminals | Concealed bulk metal objects & crowd flow | Walk / Stop pacing indicator, bar graph & LED alarms |
| Defense Sectors & Embassies | Perimeter contraband & unauthorized metal | 9 sensitivity levels, Auto Set Calibration |
| Auditoriums & Worship Places | Entry point screening & crowd management | Detachable FRP frame assembly, 840 x 610 mm footprint |
Rated for operational temperatures from 0°C to 50°C and up to 90% non-condensing relative humidity, the CHECKMATE SM4F provides dependable screening performance across both industrial factory floors and commercial reception areas.
