Model OAA-100.A3 -Leak Detection Alarm Indicators

Our alarm indicators, type OAA-100.A3, are signalling devices with optical and acoustic alarm indication from an overfill cut-out device or a leak detector. In addition to level sensors with an interface, closed-circuit loops can also be connected as transmitters. On two voltage-free output contacts of the alarm annunciator it is possible to connect an optical and an acoustic warning device.
