Wireless door magnetism 1, working principle
Door magnetism is to use exploration door, window, drawer to wait to whether be opened illegally or mobile. It is mix by wireless emissive module magnetism piece is comprised twice, in wireless emissive module two arrowhead place has " steel reed is in charge of " former parts of an apparatus, should magnetism piece and the space that steel reed provides maintain in 1.5 centimeters when steel reed canal is in close condition, once magnetism piece and steel reed are in charge of,reed is in charge of the steel when detached distance exceeds 1.5 centimeters to be able to disconnect cause open circuit, call the police alarm signal transmits to lead plane while indicator light is bright.
2, installation
Will wireless emitter is mixed magnetism piece is installed respectively go up in doorcase and door (be in normally of the door on edge and on casing) , but should notice wireless emitter is mixed magnetism piece is aimed each other, mutual parallel, span is not more than 1.5 centimeters.
3, note
(1) decrease as far as possible short with the distance between lead plane;
(2) as far as possible with there are not ferroconcrete and electric equipment between lead plane;
(3) the position of installation is preventing water or damp place;
(4) get on emitter outfit in doorcase as far as possible, magnetism piece outfit is shaken on the door with reducing emitter and will cause fall off;
Infra-red detector (infra-red detector of extensive role detector, infra-red screen sign) 1, working principle
Infra-red detector is a basis human body is infra-red and spectral and the job, be in when human body inside its monitoring area per fire detector when the activity, detector outputs alarm signal to undertake calling the police.
Infra-red of extensive role detector be on guard area is with its lens only then dot, send out ahead 110 degrees, grow 8 meters conic to explore area, inside this area, if heat up active other people,be only inside area activity, the infra-red heat energy that its send out will be absorbed.
Of detector of infra-red screen sign be on guard area is it is with lens only then dot, send out up and down 90 degrees, the left and right sides is 0.2 meters wide, grow wall of act of a 8 meters infra-red induction, inside this area the infra-red heat energy that if heat up active other people,from the course inside this area its send out will be absorbed.
2, installation
The globose end of head of will versatile join is pressed into base, the inserting that another end inserts exploration backside inside flooey, install height 2, 2.8 meters, adjust good point of view to be able to be used.
3, note
(1) decrease the distance between short exploration head and lead plane as far as possible;
(2) as far as possible with there is not the interference thing such as ferroconcrete and electric equipment between lead plane;
