General Installation Instructions
While the instructions to mount each spot detector to the floor are the
same, each model of SD connects differently with its controller. Follow these
instructions to mount your spot detector to the floor; then continue to the
directions specific for your SD.
1. Determine the spot detector’s location
2. The angle of the sense probes can be adjusted to change the sensitivity of
the SD. The closer the probes are to the floor, the smaller the quantity of
water required to trigger the sensor. Adjust the sense probes to the desired
height. Be sure the probes don’t touch each other.
3. Ram set 6/32 threaded studs in the floor on 2.5” centers or apply mastic.
4. Place the spot detector over the studs or mastic and secure.
From this point, each spot detector’s installation varies a bit. Refer to the
instructions for your particular unit.
SD
The SD is designed to primarily function with RLE controllers, specifically the
FMS, F-series, RA1x2, or the LDRA6. The SD functions like a switch - the circuit
remains open until a leak is detected. The sense probes detect a leak, which
causes the circuit to close, which then triggers an alarm. If the SD is operating
on 12-36VAC power, the circuit will reset and open automatically once the leak is
no longer present. If the SD is operating on 18-36VDC power, the circuit must
be manually reset after the leak is cleared. To do this, you must break power
to the device, which will reset the circuit. Even if the water leak is no longer
present, power must be broken to manually reset the DC-powered SD.
The SD comes with a two-wire open lead that allows it to be wired directly to
the controller’s terminal block. Connect the white/red and black leads to the
appropriate terminal blocks on the controller.
This sensor will alarm with a small
quantity of water present.
This sensor requires a larger amount of
water to be present before it alarms.

SD-Z1
The SD-Z1 is a single zone spot detector, designed for zone leak detection
systems including the LD300, LD1000, and LDRA6. RLE recommends using only
one SD-Z1 per zone.
The SD-Z1 comes with a four-wire open lead that allows it to be wired directly to
the controller’s designated terminal block. Connect the four wires - red, green,
black, and white - on the SD-Z1 to the terminal block on the controller.
