IntroductionThe DSC Meridian Photoelectric Smoke Detector incorporatesmany advanced design features to provide years of reliableoperation. It is important to follow the Installation and Operationinstructions on this sheet to ensure that the unit will functionproperly — even the best designed smoke detector will be rendereduseless if it is not connected or located properly.It is very important that you understand how to test and maintainyour system. Read the Instruction or User Manual for your alarmsystem to familiarise yourself with the Fire Alarm functions. Be sureto test your system regularly following the test procedures describedin your manual. If you should ever have problems operating ortesting your system, and especially if there are problems with theFire Alarm functions, contact your Smoke Detector Installer orDealer immediately for service.While smoke detectors and alarm systems are designed to warn youof potentially dangerous situations, no system can prevent emergencies.An alarm system is not a substitute for life and property insurance; youshould always maintain appropriate insurance coverage.How the Smoke Detector WorksAs shown in the illustration, a light source is directed across thesmoke chamber and is not normally reflected into the sensingelement. When smoke enters the chamber, the light beam isscattered by the smoke and is reflected into the sensor. Whenenough light is detected by the sensor, an alarm is activated. Onalarm, the Sounder is activated and the red LED will flash. Whenthe smoke clears from the smoke chamber, the unit willautomatically reset itself.Alarm IndicationsCondition Sounder Indicator RFLight TransmissionNo Smoke Silent Flash every Supervision40-50 s transmission every 12 min.Smoke Alarm Flash every Alarm0.67 s transmissionAutomatic Self Test Silent Flash every SupervisionFunctioning Normally 40-50 s transmissionevery 12 min.Automatic Self Test Chirp between Flash every Fire TroubleInsufficient Sensitivity LED flashes 40-50 s transmissionPush-button Test Alarm Flash every SupervisionFunctioning Normally 0.67 s transmissionevery 12 min.Push-button Test Silent Flash every Fire TroubleInsufficient Sensitivity 40-50 s transmissionMagnet-Reed-Switch Alarm Flash every AlarmTest Functioning Normally 0.67 s transmissionMagnet-Reed-Switch Silent Flash every Fire TroubleTest Insufficient 40-50 s transmissionSensitivityLow Battery Chirp simultaneous Flash every Fire Troublewith LED flash 40-50 s transmissionREAD THIS INSTRUCTION SHEET THOROUGHLY BEFOREINSTALLING AND USING YOUR MERIDIAN SMOKE DETECTORFeatures• Advanced 90° photoelectric detection pattern and speciallydesigned smoke chamber***** for superior detection and dustresistance• Unique high signal-to-noise ratio and superior RFIimmunity to prevent false alarms• Excellent smoke access provides reliable detection for allsmoke flow directions and velocities• Loud 85dB piezoelectric alarm horn• Battery-powered design for easy installation andindependence from house power sources• Uses six AA batteries and special circuit design to provideextra long battery life• Solid-state LED indicator light (red)• Visible flash light and audible trouble chirp for low batterywarning• Equipped with an RF transmitter, WLS906 cancommunicate with compatible DSC Wireless SecuritySystems• Test Button allows user to perform sensitivity test and geta local indication of test result• Magnet-activated reed-switch allows user to performsystem test• Battery removal sensor alerts user to missing battery andprevents installation of detector when no battery isinstalled• Automatic self-test once every 40 seconds provides anaudible trouble indication if the unit has insufficient smokesensitivity• Attractive styling for any decor***** Protected under Canadian Patent No. 1452296.

Limitations of Smoke DetectorsWhile the Meridian Smoke Detector has been designed for reliability,it is important to know that all smoke detectors have limitations.• Smoke detectors will not work without power. If the batteries arelow, the smoke detector will not function. See “Battery Installation”below for important information on battery use.• Smoke detectors can only generate an alarm when smoke getsinside the Smoke Chamber; anything that prevents smoke fromentering the Smoke Chamber may prevent or delay an alarm.Refer to the Guidelines for Locating Smoke Detectors on thisInstruction Sheet; it is important that smoke detectors be locatedon at least every floor of the premises, preferably in every room.It is also important to avoid obstructions, such as closed doors,that may prevent smoke from reaching the unit. A smoke detectorwill not detect a fire in the walls, in the chimney or on the roof ofa building until smoke enters the Smoke Chamber.• Smoke detectors have certain obvious limitations: they may notprovide protection for someone smoking in bed, for childrenplaying with matches, or for sudden and violent explosions. Asmoke detector is a single part of overall fire safety precautions;the smoke detector should never be seen as a substitute for acomplete fire safety program.Guidelines for Locating Smoke DetectorsResearch has shown that all hostile fires in homes generate smoketo a greater or lesser extent. Experiments with typical fires in homesindicate that detectable quantities of smoke precede detectablelevels of heat in most cases. For these reasons, smoke detectorsshould be installed outside of each sleeping area and on eachstorey of the home.The following information is for general guidance only and it isrecommended that local fire codes and regulations be consultedwhen locating and installing smoke detectors.It is recommended that additional smoke detectors beyond thoserequired for minimum protection be installed. Additional areas thatshould be protected include: the basement; bedrooms, especiallywhere smokers sleep; dining rooms; furnace and utility rooms, andany hallways not protected by the required units.A smoke detector should be located between the sleeping areaand the rest of the home as in Figure 1. In homes with more than onesleeping area, a smoke detector should be located outside of eachsleeping area, as in Figure 2. A smoke detector should be locatedon each storey of the home, as in Figure 3.Smoke from a fire generally rises to the ceiling, spreads out acrossthe ceiling surface, and begins to bank down away from the ceiling.Because of this airflow behaviour, the smoke may not be able toenter the corner where the ceiling and wall meet. In most cases, this“dead” air space measures about 4 in. (10 cm) along the ceilingfrom the corner and about 4 in. (10 cm) down the wall as shown inFigure 4. Units should not be placed in the “dead” air space.Locations to avoid:• Do not locate smoke detectors at the top of peaked or gabledceilings; the “dead” air in these locations may prevent the unitfrom detecting smoke.• Avoid areas with turbulent airflow, such as near fans, doors orwindows. Rapid airflow around the unit may prevent smoke fromentering the unit.• Do not locate smoke detectors in high humidity areas, such as inbathrooms or attics. Also avoid areas where the temperature risesabove 38°C (100°F) or falls below 5°C (41°F).• Do not locate smoke detectors in poorly ventilated garagesor kitchens; car exhaust or cooking smoke could causefalse alarms.Smoke detectors should always be installed in accordance with NFPA 72,the National Fire Alarm Code. Smoke detectors should always be locatedin accordance with Paragraph 2.1.1.1 of NFPA 72, Chapter 2.:“2-2.1.1.1 Smoke detectors shall be installed outside of each separatesleeping area in the immediate vicinity of the bedrooms and on eachadditional story of the family living unit, including basements and excludingcrawl spaces and unfinished attics. In new construction, a smoke detectoralso shall be installed in each sleeping room.”Testing Your Smoke DetectorFollow the test procedure described here or contact yourSmoke Detector Dealer or Installer for testing instructions.It is recommended that your entire alarm system be tested atleast once per week to verify the operation of all systemfunctions.Smoke Detector Unit TestTo test the smoke detector, press and hold the Test Button on thefront of the unit. When the button is pressed, the unit’s alarm shouldsound. When the button is released, the alarm should be silenced.If this does not occur, check that the batteries are the correct type,in good condition and are installed correctly (see the BatteryInstallation section).Upon completing the functional testing of the smoke detector,check the unit’s sensing chamber to ensure proper operation. Totest the sensing chamber, waft a lit cotton wick or punk stickaround the outside of the unit until a generous amount of smokeenters the sensing chamber, or the unit alarms. If the smokedetector does not function properly, call your smoke detectorinstaller or dealer for service.
