The Argus module range provides an ideal solution to the monitoring and control requirements of most fire detection and alarm systems, ranging from small and simple, to large and complex. By utilising the Argus fully digital communication protocol, reliable and fast operation is achieved even when employing the impressive 240 device loop capacity. A choice of mechanical configurations provides easy integration of the units into a variety of field locations. The VMMC120 is contained in a compact housing, which can be easily mounted inside third party equipment and provides the capability to remotely control ancillary circuits using a single set of volt-free changeover relay contacts. A bi-colour LED provides local indication of device status.
