According to another aspect of the present utility model, the technical program provides a kind of installation detection side of smoke detector
Method.The installation detection method comprises the following steps：
Mounting seat 10 is fixedly mounted on wall, now, mounting seat 10 is separated with clamshell 20, and alarm is sent out
Go out indicating alarm (smoke detector of the technical program is energized using independent current source)；
Clamshell 20 is connected (the smoke sensing device 100 of the technical program, alarm, control in place with mounting seat 10
The corresponding building block of chip 200 and connecting detection device 30 installation in installing space, these groups in clamshell 20
It can be integrally connected into part with clamshell 20 relative to mounting seat 10 and the part in mounting seat 10
Detection means 30 separates, and only need to correctly be connected clamshell 20 with mounting seat 10, you can connects corresponding circuit connecting node
Connect completion)；
Wherein, detect whether mounting seat 10 is connected in place with clamshell 20 by connecting detection device 30, work as connecting detection
Device 30 detects that the annexation of mounting seat 10 and clamshell 20 reaches predetermined link position alarm device stopping prompting alarm.
Specifically, (the company in i.e. foregoing smoke detector when for being installed using foregoing smoke detector
Detection means 30 is connect including at least light source emitter 31 and optical receiver 32), the installation detection method is further comprising the steps of：When
During the light that the light source emitter 31 that the optical receiver 32 of connecting detection device 30 receives connecting detection device 30 is launched, lead to
Cross the control chip 200 electrically connected with optical receiver 32 and detect the light intensity for receiving light, when the light intensity of received light reaches predetermined
During range of light intensity, then control chip 200 controls alarm to stop prompting alarm.Connecting detection device 30 is being utilized to installation situation
During being detected, during clamshell 20 is connected with mounting seat 10, it is understood that there may be clamshell 20 and mounting seat 10
Between connection status be in and will connect in place but the actual state not being fully connected in place, and now clamshell 20 and installation
Self-locking state is between base 10, now, the part light that light source emitter 31 is launched can be equally transmitted to
Optical receiver 32, but the luminous intensity that now optical receiver 32 can receive is than connecting the light intensity received when in place
It is low, also with regard to optical receiver 32 receive light intensity and not up to start control chip 200 control alarm stop prompting alarm light
Strong lower limit.At this moment need with mounting seat 10 to separate clamshell 20 to be reinstalled again, it is known that connection is in place.
Preferred embodiment of the present utility model is these are only, it is all in this practicality not to limit the utility model
All any modification, equivalent and improvement made within new spirit and principle etc., should be included in guarantor of the present utility model
Within the scope of shield.
