Where to install best At first you need install one in the bedroom and route way, because the bedroom
is far away from the exit usually, if you have several bedrooms, youd better install one alarm in every room. 1.2. Install it in the stairway, because stairway take an important part in emergent situation.
At least install one alarm in every floor. Install one alarm beside the electric appliances in every room. Smoke, heat and burning things will spread horizontally after rising to the ceiling,
so install one alarm in the middle of the ceiling of ordinary structure house. Let
the alarm can induce every corner. If alarm cant be installed in the middle of the ceiling for some reasons, the distance the alarm away from the wall should be beyond 10CM. If install alarm on the wall, it should be 10~30.5CM below the ceiling. (Like the diagram 1) If the length of the room or the hall is beyond 9m, you need install several alarms in the hall. Alarm need be installed 0.9m away from the highest point in room which is gradient. (Like the diagram 2) How to install alarm in moving room. The moving rooms heat insulation is poor comparing with ordinary structure rooms, the inner and outer energy exchange with cool air through very thin wall and ceiling, so a heat insulation layer form easily near the wall and ceiling, which baffle the smoke go to alarm. Installed in this structure room, alarm need be 10~30.5cm below the ceiling. If you dont know the moving rooms heat insulation, install one alarm on the wall. From the minimum safety, install one alarm in the bedroom at least.Where not fit to install. Carbarn, the burned things providing when you start auto probably lead false alarm. Like the structure in the diagram 1, where below 10CM. Under the condition that temperature is below 40or beyond 100 . Where there is much dust, the dust particle will lead the alarm do falsely or dont work. Where temperature is too high, moisture and humidity will lead false alarm. Where many winged-insect appear. Installation position is 0.9m below following position: the kitchen floor, bathroom floor and intake. Near fluorometry lamp. Installation Turn the alarm body counterclockwise and take off the bottom plate. Press the bottom plate on the installation position, mark installation hole of the plate with pencil. Bore two installation holes(6.5,height 35mm) on the sign with electric drill(6.5mm drill bit). Strike the dilatant into holes with hammer, screw the bolts (3x30) with gasket into the half of the dilatant, then hang the bottom plate on the screw (gasket press on the plate), tighten the screw. Open the battery box, press the battery into box and button it. Without battery the box cant be buttoned. Generally there is not battery when the product is out of factory, you should open the box and check it before you use it. Without battery in it, the button in the box will flip automatically, and you never button the box until you fix the battery into it (like the following diagram)
Button the smoke alarm, turn the alarm body clockwise until there is sound of beng.
Like the following diagram.
Operate and test3.1 operate: fix the battery in alarm and test it, the alarm is in testing state. When it detects smoke, the alarm will provide the alarm sound beyond 85db until it detect no smoke.
3.2 shine indication: two working ways
3.2.1testing state: flashing one time every 30 seconds indicate the operation is normal.
3.2.2alarm state: when it detects smoke and work, flash one time every 0.5 second until detects no smoke and then stops.
3.3 test: if the alarm and the battery are normal, press the test button for 2 seconds, it will be in the alarming state. If it doesnt alarm, please check if the batterys fixing is correct. If the fixing is correct, probably the alarm has some defect, please contact the supply. Do not open the alarm by yourself and dont test the alarm with fire.
3.4 if there are repetitive and interim low voltage alarm di, the interval is 30 seconds, it indicates the batterys energy is shortage. To ensure normal alarm, please replace the battery.
False alarm The design for the alarm has diminished false alarm to the minimum, a little cigarette smoke cant lead it alarm generally, but the lampblack and steam in the kitchen can lead false alarm. When alarming, check the alarm cause and confirm if it is false alarm. If it is fire, please dial fire alarm telephone, if not, check whether the installation position belongs to the 2nd section or not. Treat every alarm carefully regardless it is false alarm, and do not treat it lightly. Net alarm. If several alarms are connected, when one of them detects the alarm signal, it will alarm and the indictor flash more and more quickly, the others will alarm (the connection number can only is less than 40pcs.), but their indicators wont flash more quickly. After connection, you should test many times until there is not fault, then you can use it. The connection diagram sees the right.
