Sentrol has earned its leadership position in the manufacture of door contacts by pioneering advances such as the use of multiple reeds, “wide gapping” and numerous features that reduce false alarms. Sentrol Industrial has developed a range of innovative designs to assure both greater sensitivity and complete reliability, even in the most demanding environments. With over 400 magnetic contact sensor models to choose from, Sentrol offers the most comprehensive line of door contacts and peripherals available. Built for durability and dependability, Sentrol door contacts are conservatively rated at 10,000,000 cycles, ensuring long life. Every reed connection is hand soldered and the reeds in many models are environmentally sealed. Interlogix door contacts are tested before they leave the factory - 100% of the time. Edwards Signaling's world class manufacturing standards and attention to detail virtually eliminate all out-of-box failures. You can install Sentrol magnetic contacts quickly and with every confidence in their reliability. Many residential and commercial applications for door contacts are similar. Residential users, however, will typically be more concerned with appearance than commercial users. Commercial considerations include specific issues such as how to protect valuables in storefront windows or display cases, how to protect steel doors and windows, and how to protect trucks at loading docks. Interlogix magnetic contacts are particularly suited for use on a 24-hour loop to protect occupied areas. Under the Sentrol brand, GE Security provides professional installers with a wide range of door contacts, acoustic and seismic sensors to meet the demands of both large and small applications. For over 30 years, Sentrol has led the industry with exceptional products that are designed to be reliable and easy to install.
