Kidde DP721RT Dx700 Series Conventional Multisensor Fire Detector With Relay

Kidde DP721RT Dx700 Series Conventional Multisensor Fire Detector With RelayAll Aritech 700 series smoke detectors continuously monitor their sensitivity and operational status. Background drift is daily compensated to maintain the original calibrated sensitivity within the required limits.Once a day the detector performs a full diagnostic test that includes dynamically testing the sensing chamber and internal electronics. If a detector drifts out of sensitivity range or fails the internal diagnostics test this is reported back to the panel and indicated on the detector with a yellow fault LED.Maintenance friendly sensitivity level test modeThe 700 Series photoelectric detectors include a sensitivity test mode that may be activated by simply holding a magnet near the detectors test point. This initiates a self-diagnostic routine and provides visual indication if service is required. This test mode allows field sensitivity testing without the requirement for external meters or test gas.Field cleaning and serviceThe photoelectric sensing chamber unclips from the detector for easy field cleaning and service. During regular maintenance the detector cover can be removed the optical chamber removed and replaced by a low cost new chamber. On power up the detector auto-calibrates and returns to normal operating mode without any further intervention.The right detector for the right jobFor a truly fast and broad-spectrum detection the DP721RTA offers both optical and heat sensors. The interaction of both the smoke and heat algorithms ensure a quick response to both flaming and smouldering fires.All bases are provided with an integral locking tab for extra security if required. Bases are equipped with a shorting bar between IN and OUT that opens when the head is installed and that may be manually restored when removing the head. This simplifies cable continuity testing.Key FeaturesAutomatic self diagnostics with dynamic full detector and sensitivity testHigh false alarm immunity with floating background with drift compensationSeparate fire and fault LEDs for unambiguous alarm reportingWide operating voltage for use on most conventional systemsPolarity insensitive for carefree installationCOMNONC contacts for easy supervision on any systemManual self diagnostic with visual sensitivity indicationField exchangeable and disposable optical chamber
