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 accesso-
ries 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
top) until it unlocks. Lift the lens upward 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.
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 clear-
ance 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.
