OVERVIEW
Precision Digital offers three different light configurations in
its line of Light / Horn devices. The first option is a factory
ordered Light / Horn with a color of either red, green, yellow,
blue, or white. The second option is a Light / Horn the user
determines the light color (red, green, yellow, blue or white)
by connecting the appropriate wire. The third option is a
Light / Horn with red, yellow, and green layers the user can
turn on independently. The light on the Light / Horn can be
wired to flash (not available on PDA-LH5C) or stay steady
on and the horn is rated at 85 dB. The light and horn can be
controlled independently of each other via separate relays
on the Precision Digital meter; and since the meter's relays
can be reset in a variety of ways, there are several ways
the Light / Horn can operate. For instance, the horn can be
programmed to silence at any time via the Reset Button or
F3 front panel button (on
off automatically when the alarm clears.

For other PDA-LH models, the red wire is
the color of the light. Connect the red and
black wires for a Steady On light and red
and gray wires for Flashing light.
PDA-LH5C
Connect the LED color to the plus supply
and the black wire to the minus supply to
turn the LED on. Be aware of limitations
for applications requiring different color
lights for different alarm conditions.
PDA-LH3LC-RYG
Connect the LED color to the plus
supply for a Steady On light and LED
color and gray wires to the plus supply
for Flashing light. The black wire should
be connected to the minus supply.
CONTROL STATIONS FOR REMOTE OPERATION OF LIGHT / HORN
The PDA2360 series of plastic control stations provide a convenient way
to remotely control the Light / Horn. The control stations can mimic the
button on the front of MOD-LHX2 for remote control of the Light / Horn.
The PDA2361-R is used to reset an alarm, the PDA2361-A is used to
acknowledge an alarm, and the PDA2361-Q is used to silence an alarm.

PROVU AND HELIOS APPLICATIONS
There are a wide variety of ways these Light / Horn devices can be controlled by the ProVu’s or Helios's two or four relays to
satisfy visual and audible alarm applications. Up to 8 relays are available on ProVu meters for even more versatility. Please feel
free to contact tech support to discuss your particular application. The following examples illustrate some typical applications.
PDA-LH Models
The PDA-LH models are the simplest devices in the Series and are made up of
a single-color light and horn. A typical way to use the PDA-LH is to program the
ProVu so the horn can be silenced at any time via the Reset Button or F3 front

PDA-LH5C
The PDA-LH5C shows one color at a time and the light color (red, green, yellow,
blue or white) is determined by which wires are connected to power through the
meter’s relays. A typical application for the PDA-LH5C might involve lighting up the

red light to indicate high and low alarms and the green light to indicate everything is
OK using the meter's four internal relays:

3 Low alarm < 199 Horn Latch
2 All OK 200 to 500 Green light Auto
2 High alarm > 500 Red light Auto
4 High alarm > 500 Horn Latch
PDA-LH3LC-RYG
The PDA-LH3LC-RYG can light up red, yellow or green bands as determined by
which wires are connected to power through the meter's relays. A typical application
for the PDA-LH3LC-RYG (and the default factory setting) might involve lighting

up the green light to indicate everything is OK, the yellow light to indicate a High

the Warning and High alarms and can be manually reset at any time with the front
panel reset button:
Relay Purpose Range Light/Horn Action
1 All OK < 199 Green light Auto
2 Warning 200 to 500 Yellow light Auto

illustrates how much of this power is required to drive
various Light / Horns. If more power is needed, then
consider the PDA1024-01.
PDA-LH and PDA-LH5C Models:
Color Power Required Color Power Required
Red 17 mA Blue 15 mA
Green 15 mA White 42 mA
Yellow 23 mA Horn 20 mA
Example: 17 mA (Red Light) + 20 mA (Horn) = 37 mA total current
needed from the 200 mA supply. Available current = 163 mA
PDA-LH3LC- RYG:
Power Requirement for the horn and each color that is
turned on:
Color Power Required Color Power Required
Red 34 mA Yellow 33 mA
