Adams AD 11-V hand held metal detectors have a standard simultaneous audio/visual alarm facility along with the added ability, via the two-position rocker switch, to switch the detector to either standard “audio/visual” setting or “vibration” only mode. This feature gives the AD11-V the ability to alert the operator of a potential weapon silently. This feature has proven very useful when working in a noisy environment or if the operator wishes to conduct a search procedure, while keeping eye-contact with the subject being screened. An alarm indication is given by a piezo sounder and a high intensity LED when the battery is running low and a continuous audio/visual LED signal that the battery is exhausted.
Operating at a low energy frequency of 20 Khz all Adams hand held metal detectors use Linear Detection Technology (LDT) as the detection system. Developed in the Adams Electronics Incorporated research facility, Linear Detection Technology (LDT) produces a clean signal free from transient noise or unsafe high energy, yet enables a detection sensitivity that can detect even the tiniest fragments of metal – accurately and safely.
All the metal detectors in the general purpose range are medically tested and approved, providing no risks to pregnant women or persons with pacemakers, or any interference to magnetic recorded material. Additionally, the unit is protected again environmental conditions and waterproofing to IP64 (lEC 529). It has been tested and approved to EEC EN5008-1 Table 1. EN50082-1 Table 1:1.1 Radiated emissions. Conforms to international standards: CE mark lEC, NILEC of FCC, FAA.
