SAFETY NOTICES

Failure to follow all safety precautions and instructions may result in
property damage, serious injury, or death to you or others.

SAFETY MESSAGE TO INSTALLERS, USERS, AND MAINTENANCE PERSONNEL

It is important to follow all instructions shipped with this product. This device is
to be installed by a trained electrician who is thoroughly familiar with and will follow
all applicable national and local codes.

This device may be considered a part of the signaling system and not the entire
signaling system.

The selection of the mounting location for the device, its controls and the routing
of the wiring is to be accomplished under the direction of the facilities engineer. In
addition, listed below are some other important safety instructions and precautions you
should follow:

• Read and understand all instructions before installing or operating this
equipment.

• Do not connect this light to the system when power is on.

• After installation, ensure that all screws and threaded joints are
properly tightened.

• After installation, test the light system to ensure that it is operating
properly.

• After testing is complete, provide a copy of this instruction sheet to all
operating personnel.

• Establish a procedure to routinely check the light installation for
integrity and proper operation.

I. GENERAL.

The UniStat™ (USI) is a TYPE 4X with IP66 rating and the UniStat™ (USIS) is
a TYPE 1 status indicator for indoor use that is compact in size. Each UniStat™ status
indicator contains one base, sleeve, PCB, color LED array, lens, cap, and surface gasket.
The cap and sleeve attach to each end of the lens by twist lock joint. Two screws hold
the base and sleeve together. An O-ring between each module provides a water-tight
and dust-tight seal except for the USIS models which has slots to allow audio to emit
from the unit.

A printed circuit board runs the entire length of the base and sleeve of the
UniStat™ status indicator. The printed circuit board contains a terminal block and
circuitry for the control of a color LED array that has an average life of 100,000 hours.
The terminal block provides connection for two input power lines and eight terminals
for setting the operating modes.

-1-

The –TC model color LED array can be set to operate in one of 4 modes while
illuminating one of three colors; amber, green or red. Three terminals are used to
select the illuminated color.

The –QC model color LED array can be set to operate in one of 4 modes while
illuminating one of four colors; blue, amber, green or red. Four terminals are used to
select the illuminated color.

In addition to color selection there are two terminals which are used to select the
slow flash, Simu Strobe™, strobe flash, or steady-burn mode. The desired selection is
accomplished by contact closure between the appropriate control pin to the common
signal pin (“SEL”) on the terminal block. An additional terminal provides sound option
for the USIS models.

Table 1 identifies the terminal connections and operating modes for the UniStat™

-TC and -QC models.

The base of the UniStat™ can be surface mounted or mounted on a 3/4 inch NPT
pipe. An optional Tulip Base, Model MSTB is available for surface mounting the unit
with a 3/4 inch NPT pipe. Three Pipe Extensions, Model MSP-4, MSP-16, and MSP-32,
pre-cut in 4-inch, 16-inch, and 32-inch lengths respectively, threaded, and painted are
available ready for use with the Tulip Base, Model MSTB.

operate it. File a claim immediately with the carrier stating the extent of the damage.
Carefully check all envelopes, shipping labels and tags before removing or destroying
them.

B. Mounting.

1. Pipe Mounting.

The UniStat™ is designed for installation on 3/4" NPT pipe. To install
the UniStat on a 1/2" NPT pipe, a user-supplied reducer is required. It is necessary to
remove the base from the unit before mounting to the pipe. To disassemble the
UniStat™ follow the steps below. Reference figure 1 for additional information.

a. Remove the lens by twisting counter-clockwise (as viewed from the
top) until it unlocks. Lift the lensupward and off the base unit, retain O-ring.

b. Remove the two Phillips head #6 screws and disassemble the sleeve
from the base. The printed circuit board with LED array will remain attached to the
sleeve allowing access to the terminal block. Retain O-ring for sleeve.

c. Thread the UniStat base onto the 3/4" NPT pipe.

2. Surface Mounting.

Two surface mount options are available for installing the UniStat™.
First option is to mount the unit directly on the surface of the machine, cabinet, control
board, etc. where a flat rigid surface is available. It is necessary to remove the base

from the unit before surface mounting. To disassemble the UniStat™ follow the steps
below. Reference figure 1 for additional information. Alternatively, the UniStat™ may
be surface mounted using the UniStat mounting accessories, Tulip Base (Model MSTB)
with a Pipe Extension (MSP-4, MSP-16 or MSP-32). These optional mounting accesso­ries allow the UniStat lens to be elevated to overcome visual obstacles in the room for
greater visibility of the visual signal. Installation instructions of this second surface
mounting option are provided with the optional UniStat™ mounting accessories.

a. Remove the lens by twisting counter-clockwise (as viewed from the

b. Remove the two Phillips head #6 screws and disassemble the sleeve
from the base. The printed circuit board with LED array will remain attached to the
sleeve allowing access to the terminal block. Retain O-ring for sleeve.

c. Use the surface-mounting gasket as a template to determine the
mounting location of the unit. d. Mark the four mounting holes and the center clear­ance hole.

d. Drill the four mounting holes using a #34 drill. In the center of the
4-hole pattern, drill the large clearance hole using a 1" hole saw.

e. Knock out the four surface mount holes at the bottom of the base.

f. Postion the gasket on the surface and place the base on top of the
gasket. Secure the base with the appropriate #6 screws.

Excessive torque on the mounting screws may crack the base. Do not over
tighten the screws.

figure 1 for additional information.

1. Remove the lens by twisting counter-clockwise (as viewed from the top)

until it unlocks. Lift the lens upward and off the base unit, retain O-ring.

2. Remove the two Phillips head #6 screws and disassemble the sleeve from
the base. The printed circuit board with LED array will remain attached to the sleeve
allowing access to the terminal block. Retain O-ring for sleeve.

3. The electrical connections can now be made to the connector using 18 or
20AWG solid copper or 20AWG stranded wire.

To avoid electrical shock hazards, do not connect wires when power is applied.

4. Feed the power and control wires through the NPT opening in the
bottom of the base. Connect the wires to the connector as indicated in figure 4, table 2.
Reference Table 1 for color and function selection.

5. Before reassembling, make sure the O-ring is in place between the base
and sleeve. To reassemble the base unit, first attach the sleeve onto the base by sliding
the printed circuit board into the channels on the base. Fasten the sleeves onto the base
by reinstalling the screws removed in step 2.

6. Reassemble the lens onto the base unit, and place the O-ring between
the lens and base. Apply a clockwise twisting motion to the lens until it locks into place.

7. Test the UniStat™ to ensure that it operates as intended.

III. SERVICE.

I. GENERAL.

El UniStat™ (USI) es un indicador de estado TIPO 4X con protección IP66 y el
UniStat™ (USIS) es un compacto indicador de estado TIPO 1 para uso en interiores.
Cada indicador de estado UniStat™ contiene una base, una manga, una PCB, un
conjunto de LEDs de colores, lente, tapa, y empaquetadura de superficie. La tapa y la
manga se conectan a cada extremo del lente mediante una unión de cierre por torsión.
Dos tornillos mantienen la base y la manga juntas. Un O-ring entre cada módulo
proporciona un sello hermético y a prueba de polvo, excepto para los modelos USIS que
tienen ranuras para permitir emitir audiofrecuencia desde la unidad.
