Mounting Procedure
1
Open the housing (see
Figure 2-1
).
2
Position the base to the pre-
determined (acceptable) mounting
location. Use the gas detector base
to mark the mounting locations as
needed. The hole pattern on the
backplate is sized to mount the gas
detector onto various electrical
junction boxes. The other holes
may be used as needed to mount
the gas detector to other
structures, or onto a wall.
3
For Wall Mount, attach the
MRLDS-250 base to the mounting
surface using two #6 screws
(provided) through two of the 7
mounting holes, and be careful not
to over-tighten the screws. Refer
to
Figure 2-2
for the locations of
mounting holes on the base.
For Junction Box Mount, attach
the MRLDS-250 base to the
junction box (using mounting
hardware provided with your
junction box) through the two
junction box holes. Refer to
Figure 2-2
for the locations of the
two junction box mounting holes
on the base.
4
Unless you are ready to wire the
device (see
Section 3,
Wiring and
Configuration
), carefully snap the
cover onto the base unit.
