Description

The SPM-4000 Guardian Infinity is a complete room pressure monitor including space and reference pressure sensors and a central signal processing module. The central module includes a flush mount electrical box, 8 line graphic display for local indication of the space pressure and device configuration, six button touch pad for field configuration, LED indication of operational mode and status, and an audible alarm with alarm acknowledge switch. The Guardian Infinity offers an optional controller to provide responsive modulation of a control damper or variable speed drive guaranteeing a stable space pressure is maintained. Device monitoring and configuration is performed via LonWorks® or BACnet®-MS/TP communication networks. The SPM-4000 can also be configured to monitor air changes per hour, temperature, and humidity. An additional network communication port is available for connection to PCI’s RPM-2000 Guardian Remote Pressure Monitor that can be located at a nurse’s station.
