by Ann Withanee — June 8, 2011—Innovative electronic security and fire products manufacturer, Elmdene International Limited, a subsidiary of Potter Electric Signal, LLC, has introduced its Merlin MGD-S Graffiti Detector, which is designed to acoustically sense aerosol-propelled spray paints, and sound an alarm. It thus offers a real deterrent to what can be a costly form of anti-social behavior. It can also be integrated with remote CCTV and alarm monitoring solutions. The Merlin MDG-S Graffiti Detector was unveiled at the recent IFSEC 2011 exposition.
Typically, the compact, 120 x 80 x 50 mm, low-visibility, Merlin MGD-S unit is wall-mounted with the range of detection tied in to the installed height. At 4.5 meters an individual unit can, potentially, cover out to 7.5 meters over a 120 degree field of coverage below the sensor.
When a sound pattern associated with the use of aerosol spray paint is detected, the Merlin MGD-S uses its advanced, reliable phase-lock technology to sound an alarm within only five to eight seconds. It also features tamper protection as standard, has a wide operational temperature range (-20 to 70 degrees C), thus maximizing potential applications, and is straightforward to install, with no manual detector configuration required.
Elmdene points out that there are other anti-graffiti measures available, such as special coatings for walls, but these are not foolproof and still require cleaning following an attack, which has financial implications.
At ISFEC Elmdene showed the wired unit, which allows the Merlin to be integrated into remote alarm and CCTV monitoring solutions. A “standalone” version is also to be rolled out shortly. This will deliver the flexibility for users to easily move the Graffiti Detector from one problem area to another.
