The digital output end of controller is also connected with the control coil wire of smoke exhaust fire damper；Smoke evacuation system is controlled
System, realizes automatic smoke exhausting control.
The digital output end of controller is also connected with non fire fighting power supply break-make relay control coil wire；Sent out in fire
When raw, the control coil of the exportable signal control relay of controller cuts off whole power supply；Control accident spreads.
Manual alarm switch is connected with controller input wire;By setting manual alarm to switch, in case of emergency,
Manually alarm switch can directly it be alarmed.
Reset switch is connected with controller input wire；After Failure elimination, resetted by reset switch.
On-off transducer be arranged on it is various experiment electrical equipments on, to it is various experiment electrical equipments open or stop state carry out
Monitoring.
Display panel is arranged on laboratory outdoors；The monitoring number of each sensor in display panel real-time display time and laboratory
According to.
It also includes fire-fighting power supply, and the fire-fighting power supply provides power supply for monitoring early-warning system.
Laboratory safety state is divided into three-level by the utility model preset data section：Normally（Ⅰ）, it is slight（Ⅱ）, it is serious
（Ⅲ）, by the Monitoring Data of each sensor, for controller according to different safe coefficients, controller sends different action commands.
Controller is connected with acoustic-optic alarm, and acoustic-optic alarm is also disposed at laboratory outdoors, works as Laboratory Monitoring
Safe condition is slight（Ⅱ）It is or serious（Ⅲ）When, audible-visual annunciator will send sound and light signal, remind the personnel around laboratory
Take emergency measures.
