Fig. 5 illustrates the terminal block,
COM PORT adapter & the lead ter-
mination legend for the Waterpad.
The 8-terminal block is included with
each Waterpad. The COM PORT
adapter is included with each DD4
Dragon Drop-IR software package.
• Four of the seven leads are for the
standard Xantech IR bus, consist-
ing of +12V, IR OUT (IR -signal),
STATUS and GND.
• The remaining three leads are for
the COM PORT. The COM PORT
Adapter PCB allows direct plug-in
connection of the interface cable
that connects the PCIR-1 to the
Waterpad for program transfers
from Dragon Drop IR™. Refer to
the Waterpad portion of the Dragon Drop IR™ instructions for details.
CAUTION: The end of the cable, where the leads emerge from the sheath, is not water tight. To prevent
seepage of water up the interior of the cable to the inside of the Waterpad,
do not allow the end to be
placed under water or in a wet location
. The 6-foot cable allows sufficient length to pull the cable end
to a compartment or room area where it can be connected to the 8-terminal block in a dry environment.
Power Management
Like the Smart Pad
2 or 3
, the Waterpad™ has the ability, via the STATUS terminal, to prevent unintended
power turnoffs when power commands are sequenced with source commands.
• The Waterpad stops the first command in a sequence (the power command) when the STATUS terminal
is high (+12V DC = ON).
• Conversely, when the system is OFF, the first command (power) will be sent since the STATUS terminal
is low (0V).
• This assumes that +12V and 0V, representing a system ON and OFF condition, is applied to the STATUS
terminal (see Fig. 5)
• See Fig. 3 for STATUS connections in a typical system.
NOTE: If power management is not used (i.e. 3-wire hookups), a short jumper must be connected between
the STATUS and +12V terminals (see Fig. 5).
This powers the source button LEDs so they will come on with the selected bank. In this case, you must
put the system power command under an ON/OFF button (not under the source buttons). Also, source
commands must be placed twice under each source button in a 2-command sequence.
The user will then
need to make two initial button presses to start the system, one for ON and one to select the source
.
Also, when programming the Waterpoad for control of the ZPR68, you will need to place the source
select commands twice under each source button so that the sources can be selected after zone
turn-on.
MOUNTING
The Waterpad is designed to mount into most standard 2-gang "J" boxes in basically the same way as other
wall mounted decorator style components. The "J" boxes may be either of the new construction or retrofit
varieties. Consider the following when planning the mounting of the Waterpad:
• The Waterpad requires considerable room in the J-box.
