Description
Kidde Edwards 711U 2-Wire Photoelectric Type Smoke Detector 12/24VDC
Kidde brand conventional photoelectric smoke detectors include an interchangeable head and base, with a light-scattering optical sensor. They provide outstanding stability and respond to a wide range of fires.
A pulsed infrared LED light source and a high-speed photodiode sensing element are housed in an multi directional sensing chamber protected by an insect screen. For easy cleaning, the detector features a field-replaceable optical chamber.
Model 721UT photoelectric detectors include fixed temperature and rate-of-rise heat detectors. The 721UT provides remote alarm and trouble LED driver outputs. Also available is the 713-5U electronic heat detector head for areas too dusty for smoke detection.
700 Series smoke detectors were the industry’s first conventional self-diagnostic detectors specifically designed for the demands of commercial and industrial environments. If the detector drifts out of its UL Listed sensitivity range or fails internal diagnostics, the alarm LED flashes once a second to indicate a trouble condition. This meets NFPA 72 field sensitivity testing requirements without the need for external meters.
If they become dirty over time, the 700 Series detectors automatically adjust the alarm threshold through built-in drift compensation. If the detector ever does need to be cleaned, the patented field replaceable optical chamber makes cleaning a snap.
