New Stadium Fire Suppression Control System

This information on the Stadium Fire Suppression Control System has been provided by our valued supplier Acromag and their partner Akron Brass Company

Challenge:

Firstly, to develop a custom engineered fire suppression system for a new indoor football stadium.  However, regulations require protection against fire hazards.  Also, which could occur during monster truck rallies or other events that may have flammable material on the stadium floor area.

Solution:

Therefore, the technology used was the Akron Brass StreamMaster II Electric Fire Monitors (water cannons).  These had Style 5177 nozzles (1250 gpm) which were capable of being controlled remotely.  Acromag XT1121-000 Ethernet remote I/O modules with 16 discrete I/O and i2o peer-to-peer technology.

Result:

After performing actual operation and distance tests, a state fire marshal approved the system.

Summary:

The solution uses 4 remote controlled water cannons mounted above the first level of seating at the 20-yard lines on both sides of the field. The water stream from each monitor must travel 83 Metres to the centre of the field and be controlled remotely. An operator control panel (OCP) with an operator console is located in the stadium security room. The operator would control the direction of each monitor and open/close each water valve.

Therefore, the system includes four monitors together with four custom electric motor control panels (MCP). The operator console, with four joy sticks and switches, is wired to the OCP. Inside the OCP are four Acromag XT1121-000 Ethernet remote I/O modules that receive discrete inputs from the operator console. Communications between the security room and monitors utilises a high-speed fibre optic network.

Firstly, each monitor is controlled by a joy stick.  Plus, rotary switches for water valve open/close, fog and stream. Secondly, one XT1121-000 module in the OCP sends commands to another XT1121-000 module located in the field MCP. The technology between the two Acromag XT modules is i2o, a peer-to-peer Ethernet communication. The field XT1121-000 has outputs that match the inputs to control the Monitor. This i2o pair is repeated for all four monitors.
