Optional Integrated Systems Douglas LonWorks products are compliant to LonMark standards Larger systems that use LonWorks technology can integrate Douglas relay panels as a part of the larger system The PC computer and integration process is performed by the suppliers of integrated systems Fe i Individual elay Switches amp Technical Data CONNECTIONS Douglas relays and switches can be easiliy networked by using relay scanners equipped with network nodes Local switches and sensors are still connected directly to relays and system wide switches timers are connected to the inputs of the scanner node combination For system wide control of relays connect a standard Douglas 2 wire switch and or timer output to a scanner input By using the membrane buttons built into the scanners the relays controlled by an input are easily selected or de selected Each input of a scanner is unique That is input 1 of scanner 1 can be set to control relays connected to scanners 1 2 3 etc Input 1 of scanner 2 can be set to control a different group of relays that are connected to scanners 1 2 3 etc By attaching a WNX 2624 network node to a WRS 2224 relay scanner a simple self managed network can be established The WNX 2624 nodes are connected together with a non polarized data signal that can be connected to the devices in either way Total data signal length should not exceed 1650 feet 500m If longer lengths are require
