Plant-grid connection mouth 1 provides+24V voltages for fire detector, and auxiliary power 25 is provided by auxiliary power access port 2 for fire detector
Trouble shooting voltage.According to principle as described above, the state by observing alarm lamp can judge whether fire detector is deposited
In failure.When alarm lamp is lighted, show that fire detector quality is intact, when alarm lamp can not be lighted, shows detection
There are failures for device.
The shape that novel duplicate-power overall characteristic checking table described above passes through the alarm lamp of observation fire detector itself
State judges that fire detector whether there is failure.There are failures in alarm lamp of fire detector itself itself for this detection mode
In the case of, it may appear that detection error.Such as when alarm lamp itself there are failure and the circuit of fire detector other parts all
It is in the case that quality is intact, alarm lamp still can not be lighted after input+24V voltages and trouble shooting voltage.But at this time
The alarm signal that alarm signal output interface 3 exports is high level, shows fire detector other component other than alarm lamp
All it is that quality is intact.At this moment if it is determined that fire detector, which integrally has failure, will result in detection error.
Therefore another preferred embodiment as novel duplicate-power overall characteristic checking table described herein, Ke Yi
The upper setting indicator light of one of main power source mounting plate 22, auxiliary power mounting plate 23, the first fixture 26 or second fixture 27 connects
Mouthful, the indicator light interface is corresponding with 3 position of alarm signal output interface on fire detector, when main power source 24 connects with main power source
Entrance 1 is connected to, when auxiliary power 25 is connected to auxiliary power access port 2, the indicator light interface and the alarm on fire detector
Signal output interface 3 is connected to.It is additionally provided with indicator light (not shown) in the workbench 21, the indicator light and indicator light
Interface is electrically connected.Due to fire detector total quality is intact and other than alarm lamp other component is all intact this of quality
In the case of two kinds, the alarm signal that alarm signal output interface 3 exports all is high level so that with alarm signal output interface 3
The indicator light connected by indicator light interface is lighted, show fire detector total quality it is intact or other than alarm lamp other
Component is all that quality is intact.Both of these case can be distinguished again by the state of alarm lamp itself.If it is confirmed that lamp and
Indicator light is lighted simultaneously, shows that fire detector total quality is intact.If it is confirmed that lamp does not work and indicator light is lighted, and shows fire
Detector other component other than alarm lamp is all that quality is intact.
As the further preferred embodiment of novel duplicate-power overall characteristic checking table described herein, indicator light
A red light, a green light are could be provided as, red light and green light are electrically connected by indicator light selection circuit with indicator light interface.When
The alarm signal that alarm signal output interface 3 exports (shows that fire detector total quality is intact or removes when being high level
Other component is all quality is intact other than alarm lamp), selection circuit makes green light light；When alarm signal output interface 3 is defeated
When the alarm signal haveing is not high level (showing fire detector, there are failures), selection circuit makes red light light.Selection
Circuit itself belongs to the prior art, and any can realize selectively turns on an electrical circuit while cutting off another electrical circuit
Circuit structure can be used as selection circuit here.
In conclusion as the embodiment of the present invention content, and obviously embodiments of the present invention are not limited to that,
Functions implementing the present invention corresponding demand can be utilized according to different application environment.
