12 Fire Alarms Detectors Four Wire Series than two inches deep SuperDuct four wire detectors are suitable for installation in where space is limited SuperDuct feature removable dust filters coated circuit boards and optional gaskets to keep contaminants from components They include industry sampling tube mounting holes to simplify applications detectors use differential sensing to gradual environmental changes from false alarms A rapid change in environ conditions such as smoke from a fire the detector to automatically signal an condition but dust and debris accumulated time does not change alarm sensitivity relay output may be configured for operation of the duct detector A dedicated LED on each unit offers immediate information even when the cover closed controller can be installed up to 15 feet detector and one controller can support up two detectors Up to 15 controllers can be for multiple fan shutdown Test Reset stations are available to alarm testing and indication from a remote Two wire SuperDuct detectors are also with 5956A remote alarm LEDs Information and Specifications Assembly intelligence sensing remotely from it contacts shut down to 70 No Relay Sensitivity DC 24V AC AC 230V AC DC nom max DC C DC 24V AC AC 230V AC DC nom max DC C DC 24V AC AC 230V AC DC nom max DC C Terminals DC 24V AC AC 230V AC DC nom max DC C Terminals DC 24V AC AC 230V AC DC nom max DC C Relays 2 DC AC C DC AC C DC AC C DC AC C DC AC C DC DC DC DC DC to to to to to sec sec sec sec sec AC voltage frequency at 50 60 Hz TEMP Fire Alarms Detectors Four Wire Series sampling tube sampling tube sampling tube sampling tube sampling tube sampling tube sampling tube sampling tube test station magnetic test station keyed LED Alarm Indicator housing for high areas No velocity test kit stoppers only etc gasket kit magnet kit PCB sensor kit terminals SD 4WPCBT and Dimensions Shipping lb No Fire Alarms Detectors Four Wire Series and Dimensions Shipping lb No and Detector mounted in tandem 368.5mm 354.3mm 344.2mm 221.1mm 207mm 196.8mm 171.6mm 157.5mm 147.3mm
