F5300NB906Smoke Detector

Introduction The DSC Meridian Photoelectric Smoke Detector incorporates many advanced design features to provide years of reliable operation. It is important to follow the Installation and Operation instructions on this sheet to ensure that the unit will function properly — even the best designed smoke detector will be rendered useless if it is not connected or located properly. It is very important that you understand how to test and maintain your system. Read the Instruction or User Manual for your alarm system to familiarise yourself with the Fire Alarm functions. Be sure to test your system regularly following the test procedures described in your manual. If you should ever have problems operating or testing your system, and especially if there are problems with the Fire Alarm functions, contact your Smoke Detector Installer or Dealer immediately for service. While smoke detectors and alarm systems are designed to warn you of potentially dangerous situations, no system can prevent emergencies. An alarm system is not a substitute for life and property insurance; you should always maintain appropriate insurance coverage. How the Smoke Detector Works As shown in the illustration, a light source is directed across the smoke chamber and is not normally reflected into the sensing element. When smoke enters the chamber, the light beam is scattered by the smoke and is reflected into the sensor. When enough light is detected by the sensor, an alarm is activated. On alarm, the Sounder is activated and the red LED will flash. When the smoke clears from the smoke chamber, the unit will automatically reset itself.

WLS906-433 Battery-Powered Smoke Detectors For Residential Use INSTRUCTIONS FOR INSTALLATION AND USE Limitations of Smoke Detectors While 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 are low, 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 gets inside the Smoke Chamber; anything that prevents smoke from entering the Smoke Chamber may prevent or delay an alarm. Refer to the Guidelines for Locating Smoke Detectors on this Instruction Sheet; it is important that smoke detectors be located on 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 detector will not detect a fire in the walls, in the chimney or on the roof of a building until smoke enters the Smoke Chamber. • Smoke detectors have certain obvious limitations: they may not provide protection for someone smoking in bed, for children playing with matches, or for sudden and violent explosions. A smoke detector is a single part of overall fire safety precautions; the smoke detector should never be seen as a substitute for a complete fire safety program. Guidelines for Locating Smoke Detectors Research has shown that all hostile fires in homes generate smoke to a greater or lesser extent. Experiments with typical fires in homes indicate that detectable quantities of smoke precede detectable levels of heat in most cases. For these reasons, smoke detectors should be installed outside of each sleeping area and on each storey of the home. The following information is for general guidance only and it is recommended that local fire codes and regulations be consulted when locating and installing smoke detectors. It is recommended that additional smoke detectors beyond those required for minimum protection be installed. Additional areas that should be protected…

How the Smoke Detector Works Normally, light pulses in the Smoke Chamber do not reach the light sensor. Smoke in the Smoke Chamber deflects light into the light sensor, triggering an alarm. As shown in the illustration, a light source is directed across the smoke chamber and is not normally reflected into the sensing element. When smoke enters the chamber, the light beam is scattered by the smoke and is reflected into the sensor. When enough light is detected by the sensor, an alarm is activated. On alarm, the sounder is activated and the red LED will flash. When the smoke clears from the smoke chamber, the unit will automatically reset itself.

Dulmage KTL Certelecom Laboratory 3325 River Road Ottawa, Ontario Re: FCC ID F5300NB906 Dear Mrs. Dulmage, We have looked into the matter related to the supervisory transmission of the Product in question and have found that the manual is incorrect. The WLS 906 NB 433 does send a supervisory transmission, of approximately 40 ms duration, every 64 minutes. The manual has been corrected and is included for re- submission to FCC.

Re: FCC ID: F5300NB906 Applicant: Digital Security Controls Limited Correspondence Reference No.: 15574 Confirmation No.: EA96795 Date of original e-mail: August 11, 2000 The life safety issues confronted by us today are very difficult and painful to address. As manufacturers, we have the legal responsibility to ensure we have done everything possible to protect the consumer who does not have the ability to understand the safety issues. Reporting low battery and insufficient sensitivity are life safety issues. Ensuring that the detectors are functioning to its specifications are just as important if not vital to the detection. Low battery and insufficient sensitivity trouble conditions are now referred to as alarms. The alarm transmissions are sent only when the event occurs and are not periodic. The low battery and insufficient sensitivity conditions are also treated as alarm transmissions, that is, transmissions only occur when the event is triggered and stops when the conditions causing the events are no longer present. Fire Marshals and Public Safety Officials are looking at various methods to prevent disasters. Soon it will be mandatory that all residences be equipped with fire/smoke detectors. Though buildings may have fire/smoke detectors, they may not be well maintained or even operational. Many fires and fatalities could have been prevented had the fire/smoke detectors been operational. Poor or faulty fire/smoke detectors with bad batteries are the most common causes of failures that could have prevented fatalities. For the above reasons, we consider low battery and insufficient sensitivity vital conditions of the fire/smoke detectors. Detectors with these vital conditions must be serviced or replaced immediately. The user is constantly reminded that their lives are in potential danger. Not attending to these vital conditions, immediately, can prove to be fatal. The detection of fire/smoke is only possible if the detector is good. Hence there are alarms for the detection of fire/smoke and there are alarms for the detection of malfunctioned detectors. Both type of alarms are equally important to prevent fatalities.

Hi Ruby, As discussed this morning, please find attached the document changes. The changes in instruction/installation sheet can be found in the highlighted notes above the "Limitations of Smoke Detectors" section…
