SD-RO1-NG

$77.00 Add to Cart

Due to a manufacturing error, we have a very limited quantity of a product we are labelling the SD-RO1-NG available for immediate purchase.

The SD-RO1-NG is identical to the SD-RO1 in form and functionality, but it is missing the small grommet that lines the hole in the plastic housing where the white connecting wires leave the black plastic case in the spot detector.

Each SD-RO1-NG:

  • Has exactly the same functionality as the SD-RO1.
  • Has been thoroughly tested by our manufacturing staff to ensure it meets our quality and functionality standards.
  • Is covered by RLE’s comprehensive warranty. We will accept returns on SD-RO1-NG units, just as we do for our other products.  HOWEVER, THE SD-RO1-NG MAY NOT BE RETURNED BECAUSE IT DOES NOT HAVE A GROMMET.  These units are discounted because of the omission of the grommet, and purchasers of the SD-RO1-NG have been made aware of this cosmetic difference between the SD-RO1 and the SD-RO1-NG.

The SD-RO1-NG is a single zone spot detector with one relay output.  It can be used in conjunction with any product that accepts a digital dry contact input.

Spot detectors are ideal for small spaces, and are the most economical way to detect fluids in confined areas, such as condensation drip pans.

The SD-RO1-NG requires an isolated power supply.  Be sure to purchase the WA-AC-24-ST power supply with your SD-RO1-NG.  The PSWA-DC-24 may also be used, but if a DC power supply is used the SD-RO1-NG will be a latching device – once an alarm is detected, the spot detector will remain in an alarm state until power is cycled to the SD-RO1-NG.

  • 24VDC (±10%) Isolated @ 0.1A max.; requires RLE power supply PSWA-DC-24-ST (not included)
    • If a DC power supply is used the SD-RO1 will be a latching device – once an alarm is detected, the spot detector will remain in an alarm state until power is cycled to the SD-RO1.
