Security mantraps were invented in the 16th century, and were small mechanical devices used by landowners to catch poachers and trespassers.  Today, a security mantrap is commonly described as a small room, area or compartment that is designed to temporarily hold (trap) an individual between two doors (barriers) so that their credentials can be verified before granting access. 


Despite their widespread use, security mantraps are not referenced by either the International Building Code (IBC) or the Life Safety Code (LSC/NFPA 101), which has resulted in a plethora of terms and definitions, including, for example: security portals, security vestibules, security airlocks, security booths, security cabins, control vestibules, and personnel interlocks.   


A security mantrap may be manual or automatic, manned or unmanned, pre-engineered or built from the ground up, located indoors or outdoors, and include a variety of technologies to enhance security, safety, aesthetics, throughput, service, and overall performance.  The systems come in various sizes, shapes, styles and configurations with a multitude of finishes, glazing and door options, including ballistic and vandal resistant.  Other options and features include: metal/weapons detection, left object detection, tailgating/piggybacking detection, monoblock construction, wall mount versions, wheel chair accessibility, network interface capabilities, video cameras, intercoms, anti-passback integration, biometrics, fire alarm integration, emergency pushbuttons, manual releases, battery backup, remote operation, fail-safe/fail-secure operation, and inputs/outputs for control, alarm monitoring, and business intelligence.  


Security mantraps can also provide an attractive entrance, energy efficiency, and may be deployed without guard supervision providing an ROI in roughly 1 year.  Prior to design and construction, a security risk assessment should be completed to insure performance objectives are understood, and form, fit and function can be achieved.
