DSC is proud to introduce our new standard for life safety security, the WS4916 wireless smoke detector with built-in heat detector. This low-profile detector incorporates automatic drift compensation, high/low sensitivity trouble and early low battery indication. Sensitivity testing has never been quicker or easier. Just hold the FSD-100 test meter near the detector for a simple, clear readout. It’s UL and ULC Listed for commercial and residential installations and is perfect for those applications where running a wire to a smoke detector is just not possible.
