LVI-3800
Low Voltage Relay Controller
The LVI-3800 is a low voltage controlled relay device which can be used in several different
design options. Each option will require its own LVI-3800.
1 One LVI-3800 can be used to control sources which cannot be controlled through the
PCT-4 or PCT-8 (for example a slide projector). Please note, only one LVI-3800 can be
used for source control per system.
2 The LVI-3800 can be used to follow the source selection of a particular zone on the Delta-
88 acting as zone tracker. This setup will provide a relay closure for lowering a screen
and engaging a projector when only a video source is selected.
3 The LVI-3800 can be used in conjunction with the MC-3800 indoor controls to provide
momentary contact closures for each one of the six MC-3800 soft-keys. These buttons
can be used to control lighting, curtains, projectors, etc. Since the LVI-3800 provides a
low voltage closure when a soft-key button is pressed, a low voltage signal can be
passed to an unused port on the PCT-8. This voltage signal goes into the PCT-8's unused
port's 1/4" phone jack input. When the PCT-8 receives a low voltage (5VDC) pulse
through its 1/4" input, it will flash one IR code (programmed into that ports MAIN
function). Therefore, if you system has a home theater system where the projector
requires an IR on/off code to engage, the on/off function can be performed from the
MC-3800. When a MC-3800 soft-key (labeled ON) is pressed, the corresponding LVI-
3800 momentarily closes a specific relay which then passes 5VDC to an open PCT-8 port
(1/4" phone jack (5VDC) input). The PCT-8 will then emit the IR on code to the projector.
The LVI-3800 has several different address settings which are engaged by setting its DIP
switches. The following chart specifies these settings. Since several different options exist, and
since several LVI-3800s can be used for any option on only a specific room, you will need to
carefully set the DIP switches on your LVI-3800 (s). Furthermore, depending of the option you
need to access, you may also need to invert the polarity of the receive and transmit lines when
trying to track a particular zone's source selection. The two jumper pins on the LVI-3800 can
be pulled out and inverted making this switch
easy.
The LVI-3800 provides both a 5VDC or 12VDC
output which engages when specified to.
Furthmore, each of the eight relays (all eight used
for zone tracking - the first six are used for soft-key
control) can be set to either switch from Normally
Open (NC) to Normally Closed (NC) or to open
from Normally Closed to Normally Open. Using
a small screw driver, wedge the relay out of posi-
tion and move it over one space on the relays
receptical and re-insert the relay.

Low Voltage Relay Control Controller • Source Control
LVI-3800 DIP Switch Settings for Source Control - For Use With MC-3000 Version 1.6 or Up.
Once you have wired the LVI-3800 to the WH-3000 in the correct manner, you can program the
the LVI-3800 to provide the correct relay closure and the appropriate MC-3000 display readout
(source control only) by setting the DIP Switches on the LVI-3800. The following steps detail
the DIP Switch settings for Source Control. DIP Switch settings read left to right, switches one
to eight. "1" signifies the switch is on, "0" signifies the switch is off. The Bus Pins on the LVI-
3800 should be set to the Normal Position.
