3M Water Leak Detector General-Purpose WR-NA WRNA 1 Unit

Catalogue number: WRNA Features: ●Can be used in combination with sensors and stickers according to the application. (Leaks cannot be detected by sensors alone). ●When water gets on the installed water leak sensor, a water leak alarm is issued. (Warning lamp (for each line), buzzer, no-voltage contact signal output (all at once and for each line)) ●Detection sensitivity can be adjusted according to the sensor used and the liquid to be detected. ●Has a self-diagnosis function that checks for sensor breaks and the detection line system. ●After a water leak alarm, the alarm state will be released when the leak is fixed and the water adhering to the sensor is removed. Applications: ●Fueling rooms, around air conditioners, under pipes, etc. (Buildings, factories, apartment buildings, etc.) Specifications: ● Power supply (V): AC100 (50-60Hz), 200V compatible (50-60Hz single phase) ● Number of detection points: 1 ● Operating temperature range (℃): -15 to 45 ● Power supply: AC100 (50-60Hz), 200V compatible (50-60Hz single phase) ● Power consumption: 3W or less (when detecting) ● Ambient temperature during use: -15℃ to 45° ● Ambient humidity during use: 90% RH or less (no condensation) ● Height (mm): 148 ● Width (mm): 80 ● Width x Depth x Height: 80 x 54 x 148mm ● Applicable sensors: B-3P, S-1F, S-1FP, PS-1R, PS-2 ● External output: Non-voltage C contact (common for water leakage and sensor disconnection) ● Detection sensitivity adjustable (25KΩ to 450KΩ) ● General-purpose type Material/Finish: ●ABS resin (case body) Note: ●A separate termination kit (TR820) is required to use the sensor break alarm.
