Surface Wiring Mounting Instructions
1. Read the installation instructions appropriate for the de-
tector head to be used and determine the number of
wires used.
2. Drill out the appropriate holes using the drill centers
provided on the sides of the adaptor (see Figure 4). Do
not use conduit larger than 1/2" to connect to the
SMB600.
3. Mount the adaptor on the ceiling using the 2 keyholes
and appropriate screws or bolts (not included). The
screws or bolts must be long enough to go through the
adaptor (5/32" or 4mm) and still fasten securely to the
ceiling.
4. Pull wiring and conduit through the drilled hole(s). At-
tach nut(s) (not included) to conduit fitting and tighten.
