Effective fire prevention management systems need to be put in place to decrease the risk of losing your stock. As experience will tell, some systems fail even though regulatory fire systems are in place. In the case of Makro, an international wholesaler, the risk management system failed to detect low water pressure levels in the sprinkler systems. This drastically compromised the effectiveness of the fire prevention system resulting in a huge loss, which could have been prevented.
Using the EtherPad Digital I/O , four Digital Inputs and one Analog Input can be monitored. Two Digital Outputs are also available to switch states (this could be an alarm light to indicate a problem). Alarms or state changes can be sent via email or SMS to notify persons of the event. SMS is sent via an external GSM modem attached to the additional serial interface.
In Makro’s case, water pressure levels and events needed to be detected. For example, generators are activated to maintain water pressure levels in the sprinkler system. Digital Inputs monitor the start/stop states of the diesel and electric pump motors, which start when a fire is discovered. The Analog Input was converted to a Digital signal in the script, which monitored power to the system.
With the EtherPad Digital I/O, SANscript was used to create customized WebPages on the embedded web server. In the script, WebPages include a Status page showing the current I/O states; a History page revealing the latest alarms; and a Configuration page for setting up the alarms. A GSM modem is attached to the first serial interface to allow SMS to be sent to mobile phones when alarm conditions are indicated . An Ethernet interface allows a networked workstation to download log files, view alarms and receive email alerts.
