WD 1 Series Point Detection
The
DiT, Inc.WD-1 and WD-1-S are basic point water detectors featuring
silver-plated probes and microchip technology, a design that provides
the highest level of water detection confidence. Power for the
units may be from 12 to 24 VAC or VDC. For application flexibility,
form “C” relay points are provided for connection to Darwell's
GMP, MPR or similar monitoring equipment. The WD-1 and WD-1-S
are each housed in a height-adjustable, galvanized steel enclosure.
The
WD-1 or WD-1-S may be utilized with any “contact closure” monitoring
panel or system. To accommodate virtually all installations, the
“dry” contact points may be wired normally open or normally closed.
Once powered, relay contacts on the WD-1 remain in the same state
until water reaches the sensing probes, closing the contact. The
WD-1-S sensors are reverse acting and make contact as soon as
power is supplied to the unit. The presence of water releases
the contact and the relay returns to a non-powered state.

WD1 Low Profile Point Detector
The DiT, Inc. WD1 –LP (Low Profile) series of
Point Detectors featuring silver-plated probes and
microchip technology for the highest level of water
detection confidence. The design allows for a
sturdier floor or pan mount as well as a lower
height profile for clearances.
All WD1-LP series
detectors use the same proven and reliable WD1
electronics. All models can be operated from 12-
24 Volts AC or DC. Alarm signaling is provided
with one or two form “C” relay contacts, depending
on the model ordered. Connect the WD1–LP to a
DiT, Inc. MPR, GMP monitoring panel or a
SCADA or BMS monitoring system to complete
the monitoring package. A height adjustable,
galvanized steel enclosure is standard.
The WD1-LP models change the relay contact
state, and lights the red LED on the cover when
water is present at the sensing probes. The WD1-LP model provide a single or dual set of dry relay contacts.
The WD1-LPS models include fail-safe circuitry to signal an alarm condition for an internal malfunction
or loss of power to the sensor. The WD1-LPS models incorporate a reverse acting set of relay contacts
that are closed in a normal condition.

DD1 Drain Detectors
The
DiT DD1 is a water point detector, featuring silver-plated probes
and microchip technology for the highest level of water detection
confidence. The DD1 can be operated from 12-25 Volts AC or DC.
Alarm and control signaling is provided with form "C"
relay contacts. The DD1 can be connected to any of DiT's monitoring
systems to complete the monitoring package. The DD1 can also be
used as a stand-alone controller for cooling or water flow shutdown.
Air Conditioning
The DD1 relay contacts can be used to inhibit cooling when a high
water level in a drain pan is detected. This will prevent water
damage to the ceiling or flooring due to a clogged condensate
drain.
Water
Heaters
The DD1 relay contacts can be used to close an electric solenoid
when a water heater is dripping into an emergency drain pan. This
will prevent serious water damage to the building should the emergency
drain pan become clogged.
MOUNTING
The DD1 sensing-probe, clips to the drain pan using a galvanized
mounting bracket. The sensing probe is adjustable for maintaining
the proper water level. The control module can be mounted on any
flat, smooth surface using the mounting holes in the module feet.
