What a door frame metal detector does
A door frame metal detector detects metal objects carried by people passing through it. Pinpoint detection helps security staff locate the detected object more precisely, so a check takes seconds, not minutes. Security staff use these detectors at entrances to check for metal objects that may pose a threat, including those associated with explosive devices. Essatech also supplies handheld metal detectors for the second check.
Detection and control features
Multi-zone detection identifies the location of a metal object, and separate sensitivity settings let staff adjust each zone. An LCD display supports programming and monitoring. Relay outputs support functions such as CCTV recording, turnstile control and alarms. The features are:
- At least 9 real detection zones
- Automatic adjustment to environmental conditions
- Green and red LED indicators for passage control
- Light indicators on the side and control panel
- Separate sensitivity settings for each zone
- Metal discrimination and precise target location
- One-touch button to restore factory default settings
- LCD display for programming and monitoring
- Relay outputs for connected security equipment
Why buyers choose a walk-through frame
A frame screens people at the pace they walk. Guards do not touch visitors, queues move, and the green and red lights tell staff at a glance who to stop. Because it records the zone where metal was found, a guard can ask the person to remove the item and walk through again, which cuts arguments and speeds up the line.
Where door frame metal detectors are used
Door frame metal detectors are used for entrance security screening at these locations:
- Shopping malls
- Railway stations
- Airports
- Movie theatres
- Some political party buildings
- Hospitals, corporate offices and factories with controlled entrances
For builders, architects, MEP consultants, corporates, industries, hospitals and defence
A frame needs space, power and a clear approach, so it is easiest to plan together with the entrance design. Architects can give us the lobby layout and we advise on the position, the queue length and the extra lane for bags. Builders and commercial building owners can have the cable and power point built in before the finish goes on. Industries use frames at plant gates and stores, and hospital owners often use them at main entrances and for visitors to restricted areas. MEP consultants can include the screening point in the entrance drawings. Corporates use frames at campus and tenant entrances. Defence establishments, including Navy and Army gates and visitor entrances, use walk-through screening, and we quote within their security and vendor rules.
What you get from Essatech
Essatech supplies and installs door frame metal detectors in Hyderabad and Visakhapatnam. The job covers:
- A free site visit to check the entrance, power and flow of people
- A recommendation on the model and the number of zones
- Supply, installation and setting up of the sensitivity
- Links to CCTV recording, turnstiles and alarms through relay outputs
- A briefing for your guards on use and on handling alarms
- Service visits and support afterwards
Testing and upkeep
A detector that drifts causes false alarms or misses real ones. At each service visit we test every zone with a standard test piece, check the sensitivity settings, the lights and the relay outputs, and reset the unit if it has drifted. A daily test by your guards at the start of the shift is simple and worth doing, and we show them how.
