Smoke detecter
smoke fire
detecting alarm apparatus Working instructions
1, summarize
The smoke of initial fire may amassed under the ceiling indoors, the photoelectricity smoke detecting alarm apparatus (below named the alarm apparatus ) can detect the existence of somke in real time, Detection is accomplished by sensing scattered light from minute smoke particles or other aerosols. When detection occurs, a pulsating alarm is sounded via on–chip push–pull drivers and an external piezoelectric transducer.it makes audible and visible alarm after dealt with by electronic circuit, so it can make people know the fire as early as possible and extinguish it in the state of germination.
2, main technical details
Working Voltage:DC9V（battery supply）
Working current: monitor state less than 12μA, alarm state less than 5mA.
Alarm loudness: distance 3m,loudness not than 85db.
Ambient condition temperature: －10℃～＋60℃
Relative humidity <=95%(40±2)℃
Protective area:the height of installation for less than six meter, protective area for more than sixty square meter.
Physical dimension: Φ120mm×45mm
Weight: 153g
3, applying location
The alarm apparatus is sensitive to smoke fume, and it is also sensitive to dust, water fog and escaping gas. So it is not suitable for the site that has much dust and have always water fog. For instance the kitchen and bathroom of civil house, it is suitable for living room, sanctum, storeroom, dining—room. The site whose wind speed is more than 5m/s can,t install, because smoke fume is difficult to amass for these places.
4, installation
The distance of mount installing port for the alarm apparatus is 45mm～70mm,you must choose the position in advance and use two pieces of Φ wooden screw to attach the mount, then insert the alarm apparatus.
The position of installtion is chosen to the ceiling for the center of room. The chart as follow:
l
Figure 1.install base
For the inclined roof, the ceiling is inclined, so the angle of inclination of the alarm apparatus is not more than 45,the level distance between the alarm apparatus and the tip of roof is not more than 0.9m.The chart as follow:
Figure 2.install station
5, operation
Make ranked and stacked 9v battery insert the batter box, then the alarm apparatus can work. in order to confirm whether it is the state of work, put down the test button, it will bring out the sound of fire warning, the red fire lamp flashes, then loosen the button, the sound disappears and the lamp is not lighted. When smoke detected by aptitude judge ,the red fire lamp flashes ,after 11 sec. It makes audible and visible alarm by an external piezoelectric transducer.A piece of ranked and stacked 9v battery can use more than one year, if it emits the sound of beep every minute, it suggests the power of battery is not enough, you must immediately change the battery. A low-supplycordition does not affect the smoke detection capability if VDD≥6V.

6, cautions
The alarm apparatus has no component to let the user change except battery.if it makes trouble, please be linked with our service agency in time. The alarm apparatus must be installed after the house has been decorated. Before installation, the alarm apparatus should be kept in the position of dust control, damp control, and mildew control. You should make the sound of beep within ten seconds, the red fire lamp flashes，The product outs factory, the battery is already tookout from the battery-line, when use, the power-line and battery first be press according as its direction。
