SD-RO2

Leak Detection With Two Relay Outputs and Local Alarm Notification

The SD-RO2 is a single zone spot detector with two relay outputs plus LEDs and an audible alarm, so staff in the vicinity of the SD-RO2 immediately see and hear an alert when a leak is detected.  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.

Note: The SD-RO2 requires an isolated power supply. RLE recommends and stocks the WA-AC-24-ST.
The PSWA-DC-24 may also be used, but if a DC power supply is used the SD-RO2 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-RO2. Power supplies are available for purchase separately.

Key Features
