Frequently Asked Questions
Q:  How sensitive are Larco mats?
A:  Larco mats have a high sensitivity threshold with pressures of as little as 3-5 lbs/ft2 required for activation. In addition, Larco mats are extraordinarily strong and can withstand heavy loads of as much as 3,000 psi.
Q:  How are Larco mats affected by water and other liquids?
A:  Larco mats are totally submersible in water and other liquids. The heavy-duty outer shell is made of molded vinyl and is hermetically sealed ensuring that water cannot seep into and short out the mat's internal electrode. In addition, the heavy-duty internal electrode is bonded to the outer shell, which means that even if your Larco mat is punctured, water will not seep into and short out your mat. 
Q:  Can I order a Larco mat in colors other than black?
A:  Larco mats are available in a number of color options. The standard mat color is black, but other colors are available for an additional charge, including brown, yellow, gray, blue, red and cordovan.
Q:  Can I customize my mat with a "caution" message?
A:  Informational messages, such as "caution" or "do not step" or logos can be added to your safety mat utilizing contrasting colors to provide a visual warning to personnel. Larco has a variety of standard logos in stock, such as the international "do not enter" symbol and directional arrows. We also can custom-build logos for your specific application.
Q:  What if I need a special size that isn't listed on your standard sizes list?
A:  Larco can modify any of our standard mat sizes to create an unlimited number of "custom" mat sizes and shapes. You can specify changes in the length and/or width of a mat and/or cut notches, angles and radiuses into any of our standard mat sizes.
Q:  How many control units do I need for my mat set-up?
A:  Larco AZR-series and Zone Monitor 5000ex control units can both accept input from up to 10 mats. The Larco AZR-series controllers utilize 2-5 or 2-10  mat junction boxes to make water-tight mat connections. The Zone Monitor 5000ex has 10 built-in mat connectors that eliminate the need for junction boxes.
