In the fire alarm system, when will the relay module be used?
The relay module of different manufacturers of different types of the role is not the same, generally matching the passive contact device constitutes an alarm point (that give an address address encoding equipment, alarm system based on host is through the electrical signal alarm received to control alarm equipment) multi line relay the module is used to control the fire pump, fan and other important equipment, and do the parallel that is used in parallel with a plurality of address free equipment to give these equipment the same address is the address of the module. The above is the common different types of relay module of several functions, the specific role depends on what model, what manufacturers.
A lot of water indicators, ordinary 70 degree fire dampers. With input module, fire shutter door, fire smoke exhaust valve, cut off non fire electricity, sound and light alarm (now generally bus system), no need, general use control module or call input and output module. Multi line module for smoke exhaust fan, fire pump and spray pump
1: rolling shutter door is used to control module,2: relay module is generally used in a large area of temperature, because if you use a sense of temperature alone, too many points,
Do not know whether you have obtained the deepening of the drawings, general system plans and plans are different, in line with the final plan.
The input and output module, namely the bus type module, is used to control the alarm bell, the sound light alarm and the rolling shutter door!! Valves, elevators, radio switching, etc.. (input and output is between the device and the host control module according to the terms, can through the module to control the attached equipment and will not with the motion of the device back to the alarm host... Do you understand the function of this module?.
