Full of water, leaking water flooding this leak alarm using IC control, high sensitivity, good stability. 1, the technical parameters: 1, power options: 12VDC-220VAC 2, Shizuta Current: ≤15MA 3, Alarm current: ≤150MA 4, alarm volume: ≥90dB @ 10 ft (3 m) 5, Working temperature: 0 -. 60 ℃ 6, response and recovery time: ≤5S 1, Product Description: (1) Power light: green left, power alarm Always enter the working state. (2) reported that: a red light, when there is flooding measured, reported lights, (3) self-test light / test light: tens of seconds will flash once every self-test, the alarm is flashing continuously. 2, when the water leak is detected, the alarm red light, test light starts flashing, the buzzer "B, B, B ..." alarm sound, when not detected water test alarm will stop the alarm. 3, press the button, the test light begins to blink and buzzer "B, B, B ..." alarm sound, 4, plus a joint manipulator function, when it detects water leaks, has been connected to the robot will automatically shut down valve, thereby cutting off the water, so reducing the amount of flooding. 5, adds networking functionality, when water leak is detected, the management center or the control center at the same time receive a normally open and normally closed (NO, NC) signal. For increased wireless capabilities, the control panel will receive a wireless signal.
