The fire resistant doorsets monitor, including：
In five sections of 5V time-domains that fire resistant doorsets monitor generates, the terminal device being addressed is according to oneself state, by pre-
If the time widens the electric current on double bus.
A concrete instance is named, the implementation process of the application method is expanded on further.
Embodiment two：
Wherein, the communication information is divided into two parts：
A) fire resistant doorsets monitor sends the total 13Bits information of type, address, control and check code of terminal device to,
In：
24V--- dummy status, when 24V states continue 5ms or more, it is considered to be the first dielectric code communicated next time.
5V--- numbers 1, it is 1 to indicate that fire resistant doorsets monitor is sent to the current Bit of terminal device.
0V--- numbers 0, it is 0 to indicate that fire resistant doorsets monitor is sent to the current Bit of terminal device.
And the concrete meaning of the data of each is as follows：
Wherein, fire resistant doorsets monitor say the word parsing it is as follows：
It shields (000)：Fire resistant doorsets monitor is that Bits2~Bit 9, type and Bitl define identical end to coded address
It (is not enable the terminal device, and not on double bus that end equipment (hereinafter referred to as terminal described in address bit), which is shielded,
It registers synonymous).
Normal inspection (001)：Fire resistant doorsets monitor carries out inspection to terminal described in address bit, to obtain the terminal device
Status information.
Single-spot testing (010)：This is debug command, and fire resistant doorsets monitor can obtain terminal described in address bit by this order
The information such as current state, parameter.
Light LED (importation) (011)：If the input terminal that previous frame controller inquires terminal described in address bit has
Feedback signal inputs, then, a following frame can send out the order for the LED for lighting importation to terminal described in address bit, with
Confirm feedback states.
Extinguish LED (importation) (100)：If previous frame controller inquires the input terminal of terminal described in address bit
