ZEDK۱۶A low pressure carbon dioxide fire extinguishing system controller

The ZEDK۱۶A low pressure carbon dioxide
fire extinguishing system controller is an integral part of the core control
part of the low pressure carbon dioxide fire extinguishing system. The product
is based on the Siemens ۱۲۰۰ series PLC and is equipped with an industrial HMI
host. It is installed on the site fire alarm controller to monitor the
operating status of important equipment. Upon receiving the fire alarm
controller command, the corresponding drive unit is activated to extinguish the
fire. Operation or inerting operation.

In order to ensure the accuracy and
reliability of the fire alarm signal, the fire signal is received according to
two fire alarm signals. When the second fire alarm signal is connected, the
fire extinguishing or inerting function is started immediately. When the fire
extinguishing is started, there is a delay of ۰-۳۰S. This period can be
stopped, the low-pressure tank is a double refrigeration system, and the
protection area is ۱۶ zones. Each protection zone can be independently set as a
fire extinguishing zone or an inerting zone.
