The Informer Sensor Interface Unit (CS-SIU) enhances notification capabilities by connecting to and controlling external devices and third-party equipment.  An Informer CS-SIU automatically initiates predefined SmartMsg alerts by sensing changes in dry contact closure status resulting from a panic button or alarm system activation, PLC equipment failure, motion-sensor detection, pre-designated temperature-sensor settings, etc. Opto-isolated inputs enable each CS-SIU to sense and monitor 16 different external devices simultaneously.  Upon activation, predefined SmartMsg alerts assigned to each relay input can be sent to notify individual users or groups.

CS-SIUs provide the ability to simultaneously control and activate up to four devices or equipment through  receipt of a SmartMsg alert or activation of the relay through SmartMsg CenterPoint software.  The four output relays, which provide normally open or closed contacts, support tasks ranging from turning lights on/off to activating alarm systems, strobe lights, sirens, door locks and a host of other devices and equipment.

An CS-SIU also enables SmartMsg users to be instantly notified of changes in the status of equipment and devices at local and remote locations.  A single SmartMsg alert can activate multiple SIUs in support of multi-site notifications, thereby making it the ideal solution for large industrial complexes, healthcare facilities, schools and university campuses and office buildings.
