DSC MN220 - Installation Manual - English - Meridian Two-Wire Photoelectric Smoke Detector

MN220 Series Smoke Detectors FOR AND USE the Smoke Detector Works THIS INSTRUCTION SHEET THOROUGHLY BEFORE AND USING YOUR MERIDIAN SMOKE DETECTOR Advanced 90 photoelectric detection pattern and specially smoke chamber for superior detection and dust Unique high signal to noise ratio and superior RFI immunity prevent false alarms Excellent smoke access provides reliable detection for all flow directions and velocities Solid state LED red Indicator Light Optional auxiliary relay Form C 57 135 fixed temperature heat sensor option Magnet activated sensitivity test switch Attractive styling for any decor ULC listed S529 Protected under Canadian patent No 1452296 Other patents pending Detector Detector and Fixed Temp 57oC Sensor Detector and Auxiliary Form Relay Detector and Auxiliary Form Relay and Fixed 57oC Sensor DSC Meridian MN220 Series smoke detectors are two wire detectors intended for open area protection They are suited commercial institutional and residential fire alarm systems DSC Meridian photoelectric smoke detector incorporates advanced design features to provide years of reliable It is important to follow the Installation and operation on this sheet to ensure that the unit will function even the best designed smoke detector will be rendered if it is not connected or located properly is very important that you understand how to test and maintain system Refer to the Instruction or User Manual for your system and familiarise yourself with how the fire alarm of your system operate Be sure to test your system following the test procedures described in your manual you should ever have problems operating or testing your and especially if there are problems with the fire alarm contact your smoke detector installer or dealer for service smoke detectors and alarm systems are designed to warn of potentially dangerous situations no system can prevent An alarm system is not a substitute for life and insurance you should always maintain appropriate coverage shown in the illustration a light source is directed across the chamber and is not normally reflected into the sensing When smoke enters the chamber the light beam is by the smoke and is reflected into the sensor When light is detected by the sensor an alarm is activated On the Alarm Indicator Light will come ON and the Detector will an alarm signal to the control panel The Auxiliary Relay if is also activated on alarm When the smoke clears the chamber the detector will remain latched in the alarm until reset by turning off the power supply from the panel Units with the temperature sensor T option activate its alarm indicator light and auxiliary relay and an alarm at the control panel also When the high heat returns to normal the detector will remain latched in alarm state until reset from the control panel Resetting is by 2 seconds of power down Indications smoke or heat Relay LED every or heat test normally test sensitivity smoke or heat latched in alarm s steady Steady every s of Smoke Detectors the Meridian smoke detector has been designed for reliability is important to know that all smoke detectors have limitations Smoke detectors will not work without power Devices powered a control panel will not function if the control panel AC and backup power supplies both fail Smoke detectors can only generate an alarm when smoke gets the smoke chamber anything that prevents smoke from the smoke chamber may prevent or delay an alarm to the for Locating Smoke Detectors on this Sheet it is important that smoke detectors be located at least every floor of the premises preferably in every room is also important to avoid obstructions such as closed doors may prevent smoke from reaching the unit A smoke detector not detect a fire in the walls in the chimney or on the roof of building until smoke enters the smoke chamber Smoke detectors have certain obvious limitations they may not protection for someone smoking in bed for children with matches or for sudden and violent explosions A detector is a single part of overall fire safety precautions smoke detector should never be seen as a substitute for a fire safety program for Locating Smoke Detectors smooth ceilings detectors may be spaced 9.1m 30 feet as a guide Other spacings may be required depending ceiling height air movement the presence of joists ceilings etc Consult CAN ULC S553 M86 or other national not locate smoke detectors at the top of peaked or gabled the dead air space in these locations may prevent the unit detecting smoke areas with turbulent air flow such as near doors fans or Rapid air movement around the detector may prevent from entering the unit not locate detectors in areas of high humidity not locate detectors in areas where the temperature rises 38oC 100oF or falls below 5oC 41oF Your Smoke Detector use burning or materials test a smoke Also do not high pressure to test smoke The use of materials or pressure aerosols give misleading meaningless the detector for minimum sensitivity by activating the test To test the unit hold the test magnet against the case as below The alarm indicator light will come ON the auxiliary if equipped will be activated and the alarm control panel indicate a fire alarm When the magnet is removed the light and auxiliary relay will remain ON Turn off the voltage from the control panel to the detector for two seconds to the detector to normal the smoke detector does not function properly call your smoke installer or dealer for service sensitivity may be measured in a correlated CAN ULC S529 smoke box DSC will conduct this test for a nominal charge If a unit is found outside of its marked sensitivity range DSC will and restore the unit sensitivity to its marked range sensitivity of installed detectors can be measured without with the Gemini Model 501 Aerosol Smoke Detector Analyzer the instructions supplied with the instrument Start with the corresponding to the lowest marked detector sensitivity no should be indicated Reset with the highest sensitivity setting an should then be indicated These results indicate that the unit is its marked sensitivity range Other settings can be tried to bracket detector sensitivity to a narrower sensitivity range such as may be during annual tests to quantify any change over time Maintenance Instructions Meridian smoke detector is designed to require a minimum of If the case becomes dusty wipe the case gently a soft dry cloth If the case is greasy wipe the case gently with soft cloth slightly dampened with soapy water disassemble the smoke detector there are no user parts inside the unit Never paint the unit as paint prevent smoke from entering the unit If you are planning or repainting contact your Installer and ask that unit be temporarily removed until work is complete the unit is located in an area where it is exposed to high levels of or insects and is found to cause false alarms it may require contact your smoke detector installer or dealer Safety In The Home fires occur in the home and to minimize this danger it is that a household fire safety audit be conducted and family escape plan be developed Fire Safety Audit Are all electrical appliances and outlets in a safe condition for frayed cords overloaded lighting circuits etc If you uncertain about the condition of your electrical appliances or service have a professional evaluation Are all flammable liquids stored safely in closed containers in a well ventilated area Cleaning with flammable liquids be avoided Are hazardous materials such as matches out of the reach of Are furnaces and wood burning appliances properly installed and in good working order If in doubt have a professional Escape Plann
