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.

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.

Other patents pending. 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 familiarize 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. WLS906-433 Battery-Powered Smoke Detectors For Residential Use INSTRUCTIONS FOR INSTALLATION AND USE • 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 On smooth ceilings, detectors may be spaced 9.1m (30 feet) apart as a guide. Other spacing may be required depending on ceiling height, air movement, the presence of joists, uninsulated ceilings, etc. Consult National Fire Alarm Code NFPA 72, CAN/ULS-S553- M86 or other appropriate national standards for installation recommendations. Do not locate smoke detectors at the top of peaked or gabled ceilings; the dead air space in these locations may prevent the unit from detecting smoke. Avoid areas with turbulent air flow, such as near …

CIRCUIT DESCRIPTION Device: Low Cost Narrow Band Smoke Detector Model: WLS906LC (UA207) ESI Identifier: Description: The low cost narrowband Smoke Detector (LCNB SMK) sends the sensor status appropriately to the control unit of the wireless security system. A Smoke chamber is incorporated to sense any obscurity above its set threshold sensitivity level, If found to be higher, the sensor will immediately trigger the Transmitter to send status to the controlling unit. This unit consists of Three main circuit sections. A control section with a microprocessor, a digital controls sensor section and the RF transmitter. The control section receives status information from the sensor inputs triggered by detecting obscurity in the smoke chamber apart from its normal operating function. It is then coded to produce ASK modulation signal. This section also controls transmitter activity. The transmitter consist of an integrated chip fully implemented with a phase locked loop (PLL), divide-by-64 prescaler, a phase detector, a voltage controlled oscillator, and an automatic lock detect that disables the transmitter output when the PLL is out of lock. The external reference crystal frequency provide a complete phase-locked detector which when divide-by-64 produce the output signal frequency of 433.92MHz compensated with a matching network to antenna.
