Sub Master Detector

webmail.tradeindia.com

For the purpose of monitoring a earthquake the master is connected via data lines to sub master. The master scans all connected sub masters cyclically and decides on triggering of an alarm of all earthquake detectors. Maximum 15 sub masters can be connected redundantly to a master. The system status is indicated a visually by LED’s for operation, failure and alarm
