The LFCM7007 residual pressure controller is a powerful and reliable controller that opens the pressure relief valve directly through a residual pressure monitor or fire control.
The LFCM7007 connects the residual pressure sensor via the 485 bus or the fire bus 2 to obtain the residual pressure from the system and connects the residual pressure monitor via the fire bus 2.
Fully comply with the rules for building smoke prevention and exhaust systems;
It can be used to monitor the residual pressure in the evacuation channel, control the pressure relief valve through the PID control and adjust the residual pressure within a safe range;
This controller provides scene feedback to the monitoring host. Under normal working conditions, the residual pressure sensor is linked to adjust the pressure relief valve;
The anti-energy power supply is canceled on the spot as a source of working energy, which can flexibly build a large capacity residual pressure monitoring system;
It can carry up to 128 residual pressure sensors in addition to adjusting the opening angle of the pressure relief valve. It also supports control of up to two fans to relieve pressure.
