Attention! Ircon Modline and Modline Plus users. If you would like to upgrade your old infrared temperature systems to the latest Ircon Infrared System, life has just become a little easier. Schlemmer has designed a 2-panel plus custom enclosure system (pictured at the left) that is a direct replacement for the obsolete Modline and Modline Plus systems. The Schlemmer System features the new, more accurate, and easier to use Modline 4, 5 or 7 IR Sensing Heads connected to an enhanced, more accurate electronic package. The new electronic package has been designed to fit in the same panel cutout so installation is a snap. All alarm outputs, control outputs, retransmission outputs, comms connections, etc are connected to the same numbered connections as your existing system. Call us toll free at 800-733-3298 to discuss how we can help make the upgrade painless and simple.
