1451 and 4 Wire Smoke Detector System Sensor 400 Series plug in ionization smoke respond quickly to both fast flaming and slow smol fires as required by UL 268 Unipolar dual chamber has the sensitivity needed to quickly detect smoke and stability needed to avoid false alarms Unique dual unipolar sensor Provides exceptional stability Factory preset at 1.9 nominal sensitivity Stable operation up to 1,200 feet per minute 6 meters per air velocities Removable cover for field cleaning Two visible LEDs in standby Sealed against dirt insects and back pressure Three year limited warranty Field metering of detector sensitivity Built in test switch Low standby current Built in tamper resistant feature Designed for direct surface or electrical box mounting 360 field viewing angle of the visual alarm LEDs Easy plug in of the head to base SEMS screws for easy wiring Optional recess mounting Field adjustable sensitivity screening 0.020 0.508 mm openings to contribute to life safety fire protection and property Superior to photoelectric detectors in detecting fires Superior to bipolar detectors in avoiding alarms Operation 400 Series plug in ionization smoke detectors contain a dual source dual unipolar chamber detection design will sense the presence of smoke particles produced by combustion as well as slow smoldering fires Additional features include a blinking LED standby status indicator easily visible alarm indication and provision for convenient test and metering back of the detector is sealed to block back pressure air The chamber is protected by a fine mesh 0.020 0.508 screen to minimize problems with dust dirt and insects cleaning is required it is easy to remove the cover with a tool and obtain access to the screen and chamber to a thorough
