The QuadScan II has been developed with an abundance of built-in, flexible features that make it the ideal receiver to economically centralize display and alarming for up to four gas transmitters, fire detectors, or other 4-20 mA instruments. QuadScan II’s in-the-field “Channel Expansion” feature allows users to initially purchase only the channels they need. Unused channels can then be easily activated with the purchase of a passcode. Housed in a NEMA-4X wallmount enclosure, QuadScan II provides power to 2-, 3-, or 4-wire transmitters and is available with an uninteruptable, battery-backed power supply to ensure consistant operation during power outages. The highly visible interface includes a backlit LCD and bright LEDs that display each channel’s concentration and alarm status while the built-in, 85 decibel horn provides audible notification to personnel of alarm conditions. The LCD’s six alpha-numeric characters can be programmed to identify each input. Standard concentration units such as PPM, PPB, or % are selectable. QuadScan II provides 0/4-20 mA outputs for retransmission to other system controllers such as a DCS or PLC. Outputs are easily field calibrated to overcome line loss. QuadScan II provides common low alarm, high alarm, fail, and horn relay outputs. The alarm relays can be programmed to operate with time delay, as failsafe/non-failsafe, and automatic/ manual reset. A front panel “horn silence” button enables user to deactivate the horn relay during alarm conditions, while the “reset” button deactivates latching alarms when alarm conditions have ended. For additional relay options, QuadScan II offers powerful relay programming features through a separate external relay module with a built-in power supply that provides eight individual 5 amp relays. Features • Accepts input from any 4-20 transmitter. • Individual, simultaneous display of each channel’s output • Individual Inhibit/Fail, Warn, and Alarm LED’s • Common 5A SPDT relays for Fail, Warn, Alarm, and Horn. Programmable time delay, failsafe/ non-failsafe, and manual/automatic reset. • Optional relay module for up to 8 relays. Programmable and assignable to provide: - relay activation for each channel - voting logic - zoning logic • 0/4-20 mA output for each channel • Universal 90 - 280 VAC power supply • Remote relay reset • Programmable “Lock-Out” mode • Built-in Horn • Optional 24 Vdc battery back-up
