The detector is effective in detecting LPG leakage. It is positioned in such a way that it detects leakage instantly and once it is detected the valve cuts off the gas supply in less than a sec. The detector also provides potential free contact output (NC & NO). This can be used to connect gas alarm panels, intrusion alarm panels or video door phones with gas sense input. Vighnaharta Securityâ€™s aim is to provide reliable electronic safety, security, surveillance and automation solutions to customers.
