Information Information AUTOCALL ISN 550I ISN 550P are part of our range of 550 series all of which plug into common set of interchange bases and communicate the AUTOCALL TFX series Surface mounted circuitry allows for a low profile design Card 550 series smoke detectors continu measure smoke density and report this as an analog value to the TFX series control panel The TFX panel uses software algorithms analyze the transmitted value for pre alarm trouble or service conditions AUTOCALL TFX panel maintains a average of each 550 detector trans analog values This average is used as long term level of airborne and or contaminants against which current analog value is compared This that the detector sensitivity remains over time If the detector moving value exceeds a preset threshold a signal is annunciated at the TFX series panel This signal the operator that the detector requires and or maintenance to prevent un alarms to an actual alarm condition the TFX panel will report a lower pre alarm condition This is a condition which alerts the operator to pending alarm address of a 550 series detector is set the base by means of an Xpert Card which into a slot at the side of the detector The detector address is printed on the Card and is visible from the floor It is necessary to ascend a ladder remove detector from its base or to read a set of switches to determine the detector Detector heads may be removed replaced without system reprogramming Series Detector the universal detector extract tool extension poles all testing and mainte functions may be performed from the which reduces service and routine costs See catalog page 261 more information on detector accessories inch detector bases are available A terminal on the detector provides a output for connection to a remote Wiring connections are nonpolarized ease of installation unless the remote output is used Design Design Design Design Design ISN 550I and ISN 550P detectors have molded white polycarbonate

AND PHOTOELECTRIC DETECTOR Series Series Series Series Series detector utilizes a dual ionization design which consists of an reference chamber and an outer chamber The outer smoke cham has smoke inlet apertures which are with an insect resistant mesh A radioactive source ionizes the air both chambers The ionization a small electrical current to flow smoke enters the chamber current decreases This effect is greater in outer smoke chamber than in the reference chamber The current between the two chambers is measurement of smoke density which transmitted to the AUTOCALL TFX se control panel upon interrogation twin chamber design provides compensation for atmospheric and temperature and is insen to dust that may deposit on the ra source chamber of the ISN 550P photo detector is an optical arrange consisting of two main parts an LED and a photo diode light re The LED emits a burst of colli light every 2 seconds In clear air the photo diode will not re light from the LED due to its ar within the chamber smoke enters the chamber it light onto the photo diode which sensed by the detector electronic The intensity of light on the diode is a measurement of smoke which is transmitted to the AU TFX series control panel upon ensure maximum reliability the emits light modulated at about and the photo diode will only react receiving light at this frequency and Wiring and Wiring and Wiring and Wiring and Wiring detector base mounts directly to a 1 2 88.9mm octagonal or a 4 square electrical box using 2 8 32 screws Refer to NFPA 72 spacing location and other guide connections to the terminals in detector base are nonpolarized and such that a missing detector head interrupt the control panel initiating causing a trouble condition at the panel functional tests may be per using the IA MED Smoke Detec Test Pole and IA MTA Aerosol Test Detectors may be removed and from the floor using the IA MET Tool is recommended that at least once year the detector head should be by using the suction from a cleaner Cleaning may be re more frequently if the detector contains so
