Siemens FDBZ492-HR Fire Alarm Duct Smoke Detector
These devices are new. They were purchased for installation on a new system prior to the customer opting for an incompatible brand of FACP. These devices shipped with brand new air handler units but were removed prior to installation. They may have some physical scratches but are brand-new. We have six of these devices available for individual sale. No guarantee of functionality or compatibility is offered by the seller. These are used devices offered as-is.
