Control cabinets SA-259 and SA-259-02 are designed to monitor volume of the foam former and control during the process of its operation in automatic firefighting system.
Functions
- reception and processing of impulse signals from flow rate sensor (for SA-259-02 from two flow rate sensors), analog signal (4-20mA) from pressure sensor (for SA-259-02 from two pressure sensors), reception of input digital signals
- delivery of digital control signals according to specified algorithms
- automatic control, indication and signaling of ultimate values, level of foam former
- measurement, computation, indication and delivery in the telecontrol system of actual , cumulative and increasing value parameter
- adjustment of system time
- diagnostics and indication of equipment operability
- system information protection from illegal access using passwords and lock words
- information transfer in the telecontrol system via interface RS-485 as per protocol MODBUS RTU
- memorization of accounting parameters values in controller at electrical power failure
