Designed to provide reliable smoke detection, the WS4916 is a lowprofile wireless photoelectric smoke detector that is ideal for difficultto-wire residential or commercial applications.
no wires to run, installers are able to save time and move more quickly through the installation process. All the WS4916 requires for installation is a screwdriver and any DSC 433 MHz wireless receiver.
The WS4916, compatible with all DSC 433 MHz wireless receivers, features a built-in alarm horn, integral dual-sensor heat detection, automatic drift compensation and an easy-maintenance removable smoke chamber. Long-life lithium batteries provide extended operation without replacement. Precise and quick sensitivity testing of the unit is easily accomplished with the FSD-100 handheld test meter.

DSC is committed to reducing false alarms and has integrated a number of features into the WS4916 to provide reliable detection. One important feature is drift compensation. It provides a constant level of sensitivity performance for extended operation. As dust accumulates in a detector it adjusts to maintain the original factory-set sensitivity, thereby minimizing the potential for false alarms. If the detector reaches its limit of compensation, it will indicate a trouble condition well before the sensitivity increases to a level where false alarms will be generated.

Non-Contact Sensitivity Testing
Specifications
Precise and quick sensitivity testing is easily accomplished with the non-contact FSD-100 handheld test meter. Powered by a standard 9V alkaline battery and small enough to fit inside a shirt pocket, the FSD-100 holds 500 readings that can be downloaded to any computer. To initiate a reading, a technician simply holds the FSD-100 near a DSC smoke detector and activates the detector’s test button.
