Inside,two sets of SPDT(Form C) <br /> • Visual switch activation <br /> synchronized switches are enclosed in a durable terminal block <br /> • Audible switch activation(73 dBA) with an layout designed to make wiring easy.The wire-ready COM <br /> • Field-replaceable timer/switch assembly terminals are on a different elevation with a large barrier between <br /> switches and easy-to-read,raised,textured lettering.An optional <br /> • Accommodates up to 12 AWG wire cover tamper switch securely snaps into place, no tools required. <br /> • Switch synchronization activates both alarm panel <br /> and local bell or horn strobe The WFDNFS and WFDNFT incorporate a mechanical time delay <br /> • Tamper-resistant cover screws feature that minimizes the risk of false alarms due to pressure <br /> surges or air trapped in the fire sprinkler system.The large and <br /> • Wire-ready terminals <br /> easy-to-turn timer dial makes setting the waterflow detector easy <br /> • Improved wiring with new terminal block layout with high-contrast,pad-printed markings.The dial offers three tabs <br /> • Snap-in optional cover tamper switch to help with turning:the largest tab is located on the dial position <br /> for approximately 60 seconds and a notch in the dial indicates <br /> approximately 30 seconds,making the detector easy to set in dimly <br /> lit locations. <br /> The WFDNF series is designed for accuracy and repeatability. <br /> Agency Listings Detectors also offer improved performance during vibration in riser <br /> applications where detectors are exposed to a large in-rush of water. <br /> C 44) US = <br /> LISTED <br /> S739 7770-1653:0501 <br /> WFDS85302•06/08/17•Page 1 <br />
