优选ABS材料，有良好的防火阻燃性可拆卸底座设计，方便固定和取下真材实料用的放心简单又方便，迅速作出反馈光电感烟探测器也是点型探测器，它是利用起火时产生的烟雾能够改变光的传播特性这一基本性质而研制的。
根据烟粒子对光线的吸收和散射作用。
光电感烟探测器又分为遮光型和散光型两种。
一般的点型光电感烟探测器属于散光型的，线型光束探测器是用的遮光型的。
工作原理光电感烟火灾探测器的工作原理是一感光电极处于激光照射下发生电信号，当火灾烟雾遮蔽激光时，电极失电，发出报警信号。
点型光电感烟探测器的红外发光元件与光敏元件(光子接收元件)在其探测室内的设置通常是偏置设计。
二者之间的距离一般在20-25mm．在正常无烟的监视状态下，敏元件接收不到任何光，包括红外发光元件发出的光。
在烟粒子进入探测室内时．红外发光元件发出的光则被烟粒子散射或反射到光敏元件上，并在收到充足光信号时，便发出火灾报警，这种火灾探测方法通常被称做烟散射光法。
点型光电感烟探铡器通常不采用烟减光原理工作．因为无烟和火灾情况之间的典型差别仅有0．09%变化这种小的变化会使探测器极易受到外部环境的不利影响。
线型光束感烟探测器通常是由分开安装的、经调准的红外发光器和收光器配对组成的；其工作原理是利用烟减少红外发光器发射到红外收光器的光束光量米判定火灾，这种火灾探测方法通常被称做烟减光法。
区别光电感从实际使用方面来看．二者的区别是．点型光电感烟探测器适用于设有小型空间的建筑．即适用于天棚高度在12m 以下的房间，探测面积为60-80m2,线型光束感烟探测器适用于设有高天棚和大型空间的建筑，一只线型光束感烟探测器的保护面积相当于18只点型光电感烟探测器的保护面积，特别适用于探测位于地面处的阴燃火。

GEM-SMK 高质量光电烟感设备说明书
1Description: The GEM-SMK is a high-quality photoelectric smoke detector with built-in supervised digitally-coded radio transmitter. It is compatible with Napco’s GEM-RECV Series supervised security receivers that monitor alarms, restores, low battery and status.During normal operation, the LED on the GEM-SMK flashes once every 30 seconds. As soon as smoke is detected, the GEM-SMK sounds a local alarm and the transmitter sends an alarm signal to the supervised receiver. The alarm signal is repeated every 10 seconds thereafter as long as smoke is still present. A restore report is sent when the smoke detec-tion chamber clears. Supervisory status reports are sent from the GEM-SMK every hour.Coding switches are not required or used in the GEM-SMK. Each transmitter is assigned a unique identification code number at the factory.R333 Bayview Avenue Amityville, New York 11701For Sales and Repairs, (800) 645-9445 For Technical Service, (800) 645-9440Publicly traded on NASDAQ Symbol: NSSC© NAPCO 2008The smoke detector and transmitter are powered by one 9-volt alkaline battery and one 3-volt lithium battery (supplied) which can power the unit for at least one year.

For your information, the National Fire Pro-tection Association's Standard 72, reads as follows:11.5.1 One- and Two-Family Dwelling Units.11.5.1.1 Smoke Detection Where required by applicable laws, codes, or stan-dards for the specified occupancy, approved single- and multiple-station smoke alarms shall be installed as follows: (1) In all sleeping rooms. Exception: Smoke alarms shall not be required in sleeping rooms in existing one- and two- family dwelling units. (2) Outside of each separate sleeping area, in immediate vicinity of the sleeping rooms. (3) On each level of the dwelling unit, including basements. Exception: In existing one- and two-family dwelling units, approved smoke alarms powered by batteries are permitted.11.8.3 Are More Smoke Detectors Desirable? The required number of smoke detectors might not provide reliable early warning protection for those areas sepa-rated by a door from the areas protected by the required smoke detectors. For this reason, it is recommended that the householder consider the use of additional smoke detectors for those areas for increased protection. The additional areas include the basement, bedrooms, dining room, furnace room, utility room, and hall-ways not protected by the required smoke detectors. The installation of smoke detectors in kitchens, attics (finished or unfinished), or garages is not normally rec-ommended, as these locations occasionally experience conditions that can result in improper operation.There exist certain situations where the presence of a smoke alarm is not ef-fective, such as smoking in bed, the testing of gas leaks with a flame or for warning against the existence of high carbon monoxide levels inside a family living unit. Current studies have shown smoke alarms may not awaken all sleeping individuals; it is therefore the responsibility of individuals in the household that are capable of assisting others to provide assistance to those who may not be awakened by the alarm sound and to provide assistance to those who may be incapable of safely evacuating the area unassisted.For family living units with one or more split levels (i.e., adjacent levels with less than one full story separation between levels), a smoke detector required as above shall suffice for an adjacent lower level, including basements.Exception: Where there is an intervening door between one level and the adja-cent lower level, a smoke detector shall be installed on the lower level. •Ceiling-mounted smoke alarms should be located in the center of the room or hall, or not less than 4 inches from any wall. When the detector is mounted ona wall, the top of the detector should be 4 to 12 inches from the ceiling.•Do not install smoke alarms where normal ambient temperatures are above 100°F (37.8°C), below 40°F (4.4°C) or greater than 92% humidity unless the alarm has been determined to be capable of being used at installation points with higher or lower ambient temperatures. Also, do not locate alarm in front of air conditioners, heating registers, or other locations where normal air circula-tion will keep smoke from entering the detector. Installing smoke detectors in kitchens, garages or furnace rooms is NOT recommended.All installation wiring must be in accordance with the provisions of Article 210 of the National Electrical Code, ANSI / NFPA 70. All protected premises fire alarm systems shall be maintained and tested (at least once every month) in accordance with NFPA 72. FIRE PREVENTION AND ESCAPEThe purpose of an early warning smoke alarm is to detect the presence of fire in its early stages, and sound an alarm giving the occupants more time to exit the premise before the smoke reaches a dangerous concentration level.Fires start even with the best of housekeeping and fire-prevention procedures. Fire is an unexpected event. Early warning detection alerts occupants in time to act.KNOW FIRE HAZARDS. No detection device can protect life in all situa-tions. Therefore, safeguards should be taken to avoid such potentially dangerous situations as smoking in bed, leaving children home alone, cleaning with flammable liquids such as gasoline.The best fire protection is minimizing fire hazards through proper storage of materials and general good housekeeping techniques. A cluttered basement, attic, or other storage area is an open invitation to fire.Careless use of combustible materials and electrical appliances, or overloading of electrical outlets are other prime causes in starting fires.It is most important that explosive and/or fast-burning materials be eliminated from the home if at all possible.Even after proper precautions have been taken, fires can start. Be prepared.IN CASE OF FIRE. Leave immediately. Don’t stop to pack or search for valuables. In heavy smoke, hold your breath and stay low -- crawl if necessary. The clearest air is usually at the floor.If you have to go through a closed door, carefully feel the door and door knob to see if undue heat is present. If they seem relatively cool, brace your foot against the bottom of the door with your hip against the door and one hand against the top edge. Open it slightly. If a rush of hot air is felt, slam the door quickly and latch it. Unvented fire tends to build up considerable pressure. Be sure all the household realizes and understands this danger.Use your neighbor’s phone or a street fire alarm box. The job of extinguishing the fire should be left to the professionals. Too many unforeseen things can occur when inexperienced people try to extinguish afire.BE PREPARED. Perform fire drills regularly. Use them to assure recogni-tion of an alarm signal. For your protection, simulate different circumstances (smoke in hall, in living room, etc.). Then have everyone react to the situation.Draw a floor plan and show two exits from each room. Frequently, a knotted rope or ladder from a window will serve this purpose. It is important that children be instructed carefully, because they tend to hide in times of crisis.It is imperative that one meeting place outside the home be established. You should insist that everyone meet there during an alarm. This will eliminate the trag-edy of someone reentering the house for a missing member who is actually safe.If you have children and/or invalids residing in your household, you can help your fire department. Most fire departments have window decals available for use in children’s or invalid’s bedrooms. Properly used, these decals will quickly identify sleeping quarters of these individuals and show the department where to look first for members of your household.Additional information on Household Fire Warning is available at nominal cost from The National Fire Protection Agency, Batterymarch Park, Quincy, MA 02269.

光电式感烟报警器说明
光电式感烟报警器的安装与调试红外光电式烟雾传感器将烟雾颗粒作为被测对象，通过烟雾颗粒对发光元件发出的红外线的散射作用，在接收元件端产生电量的变化，通过判断电量的变化确定烟雾报警器的状态。
下图为光电式感烟报警器的电路原理图。
火灾报警器集成电路MC145012MC145012集成了报警器的全部功能，只要外接红外线发射电路、接收元件及扬声器等，就可构成一台火灾报警器。
下表为MC145012引脚功能。
电路使用声光报警，电路工作时，MC145012集成电路6脚输出高电平驱动VD1发出红外线信号，由VD2接收，VD1和VD2安装成不能相互直射的位置，当不存在火灾引起的烟雾时，LED2输出为0；如果有烟雾，则红外线因烟雾而发生散射，使VD2能接收到红外线，触发报警。
S为测试开关，在没有烟雾时闭合S，16脚接通电源，芯片内部就会模拟报警状态，发出报警信号，断开开关S即恢复正常工作状态。
微调电位器Rp可以调节报警器的报警脉冲宽度，脉宽增加，即报警检测所需时间变长，脉宽减小，即报警时间变短。
C6 C8 R12组成增益调节电路，可以调节系统的放大倍数，也可以作为一种调节灵敏度的方法。
在有烟雾时，由于烟雾颗粒造成的光电二极管的变化很小，因此内置放大电路，调整C6 C8 R12的参数，即可调整放大器的增益倍数，达到调节灵敏度的效果。
其中C6作为粗调元件单独使用，C8作为增益的微调元件，需要与R12配合使用。
时钟电路为RC电路，由R2 R6 C2组成，向12脚提供周期性的脉冲信号。
电源低压报警电路是在系统电源电压过低时发出报警信号，提示及时更换电池，R1 R3串联在电源电压和11脚之间，向15脚提供电源最低允许电压。
当电源电压小于最低允许电压时，9脚输出一个高电平，推动复合三极管输出，提示报警，调节R1与R2比值大小，可以改变电源最低允许电压值。

博世Fire Alarm Systems F220 光电感烟探测器 产品说明书
u Two-wire or four-wire basesu30 ft (9 m) maximum spacing between detectors u Optional CO-sensor, heat-sensor enhanced detection chamberu Clean chamber without removal or disassembly u CleanMe signaling capabilityThe F220 Photoelectric Smoke Detectors are UL Listed, open-area photoelectric smoke detectors. Use them with commercial fire protective signaling systems and household fire warning systems (see NFPA 72, the National Fire Alarm Code). These smoke detectors scatter light using a pulsed infrared source operating with a gated, high-speed, photodiode infrared sensor. The symmetry of the optical chamber allows 360° uniform smoke entry, but minimizes external light entry. The detectors use low current electronic circuitry, so they can connect to 12 VDC nominal or 24 VDC nominal power source circuits. FunctionsCompatible BasesConfigure the detectors into two-wire or four-wire versions by selecting the appropriate mounting base. These detectors are compatible with any of theF220‑B6 bases:•F220-B6 12/24 VDC Two‑wire Mounting Base•F220-B6R Standard 12/24 VDC Four‑wire MountingBase•F220-B6RS 24 VDC Four‑wire Mounting Base withSounder•F220-B6C 12/24 VDC Four‑wire Mounting Base with Auxiliary Relay•F220-B6E 12/24 VDC Four‑wire Power SupervisionMounting Base•F220-B6PM 24 VDC Four‑wire Addressable MasterBase•F220-B6PS 12/24 VDC Four‑wire Addressable Base Monitoring the Detection ChamberThese detectors have several features that work together to maximize the performance of the optical chamber:•Compensation: The detector monitors the chamberfor the effects of dust build-up within the chamberand automatically compensates for these effects. Ifthe chamber becomes contaminated beyond itsability to compensate, the green LED flashes every4 sec to indicate trouble.•Chamber Check Self-diagnostics: The detectorautomatically indicates visually if the calibration is out of the factory-listed range. This meets NFPAguidelines for sensitivity testing, because you canvisually inspect the detector and check the flash rate of the LED. If the calibration is out of range, the green LED on the detector flashes once every 4 sec. Thisindicates that the detector must be cleaned following the instructions provided with the detector.•CleanMe Mode: Indicates if the calibration is out of the factory-listed range by sending a trouble signal to the CleanMe-compatible control panel, if so programmed.•Chambermaid: The detector has a unique cleaning mechanism. Use the valve on the back of the detector to insert the nozzle of a can of clean, dry compressed air. Clean the chamber with a short (1 to 2 sec) blast of air.Heat and Carbon Monoxide EnhancementsThe detectors are available with an optional fixed-temperature heat sensor, a carbon monoxide (CO)sensor, or a combination of heat and CO sensors.These optional sensors enhance the operation of the smoke detector by reducing false alarms.•Carbon Monoxide: Without the presence of CO, a normal byproduct of combustion, the detection chamber is half as sensitive to smoke as a standard commercial photoelectric smoke chamber. This reduces false alarms. When the sensor detects CO,the detection chamber's sensitivity to smokeincreases so it equals or exceeds that of a standardcommercial photoelectric smoke chamber.NoticeThe F220-PTHC detects carbon monoxide (CO) as a component of a fire. It is not a CO detector and cannot activate an alarm in the presence of CO only.•Heat: When the heat sensor detects a temperature rise, the photoelectric chamber becomes more smoke sensitive. The heat sensor initiates an alarm if the ambient temperature exceeds +135°F (+57°C).Dual-color LEDA dual-color LED indicator flashes green every 8 sec when the detector has power and the smoke sampling circuitry is working. If CleanMe is enabled, the green LED double flashes (two flashes a half second apart)every 8 sec to indicate normal operation. The LED turns red if an alarm is sent. After the alarm condition clears, reset the detector by interrupting its power. If the chamber becomes contaminated beyond its ability to compensate, the green LED flashes every 4 sec to indicate trouble.Test FunctionsThe F220 Photoelectric Smoke Detectors feature a unique magnet operation and sensitivity test function.Test the detector's operation by placing the magnet next to the detector's LED for three consecutive flashes. This causes the detector to send an alarm.Placing a magnet next to the detector's LED for atleast one red flash but less than three flashes activates the detector's sensitivity mode.Tamper DetectionWhen detector heads are correctly installed in any of the F220-B6 bases, the positive power line provides tamper detection. The control panel initiates a troublesignal if a detector is removed from its base.

探测器可能探测不到建筑的其它楼层上所发生的火灾。因此，建筑的每一楼层都应装有探测器。

感烟探测器也有探测局限性。离子型探测器具有广泛的火灾探测功能，但其在探测快速燃烧及明火焰型的火情 方面比缓慢、阴燃型的火更好。光电探测器对阴燃火比对明焰火的探测效果更好。由于火情的发展各式各样，且 经常是对其蔓延无法预料，所以没有哪一种探测器效果总是最佳的。而对某一探测器而言，不能保证其总会对任 何种类的火情都产生及时报警。一般而言，对那些由于不充分的防范措施、猛烈的爆炸、泄漏的煤气、诸如清洗 稀释剂之类的可燃液体的不良储存和其它安全事故或人为纵火或儿童玩火所引起的火灾，不能指望探测器会及时 发出报警。用于高风速场合的感烟探测器会因为频繁和快速的空气交换稀释了烟的浓度而推迟报警。此外，高风 速的环境会产生更大的灰尘污染而需要频繁的维护保养。
A 功能测试：测试磁铁（M02-04-01 或 M02-09-00）
2251B、2251TB 和 2251TMB 型探测器可以用测试磁铁进行功能测试。测试磁铁会模拟探测室里
