Classification of Fire Linkage Controllers – Functions and Performance of Fire Linkage Controllers

The fire linkage controller is the core component of the fire linkage control equipment. It receives fire alarm information from the fire

alarm controller and implements linkage control and status monitoring of automatic fire-fighting equipment according to preset logic. The fire

linkage controller can directly send control signals and control the controlled

equipment on site through the driving device. For situations where the control logic is complex and it is inconvenient to achieve direct control

on the fire linkage controller, the controlled equipment can be indirectly controlled through fire electrical control devices (such as fire shutter controllers, gas fire extinguishing controllers, etc.).

1、 Classification
Fire linkage controllers can be classified according to their structural form, usage environment, and explosion-proof performance. According to

the structural form, it can be divided into cabinet fire linkage controllers, desktop fire linkage controllers, and wall mounted fire linkage controllers (see Figure 2-2)
According to the usage environment, it can be divided into land-based fire linkage controllers and marine fire linkage controllers. According to

explosion-proof performance, it can be divided into explosion-proof fire linkage controllers and non explosion-proof fire linkage controllers
