Installation Instructions for Optional Fixture Mounts
Wiring the DC Beacon to the CMXC-SB
and PMXC-SB
The CMXC-SB is not suitable for use with through-branch circuit
conductors.
SHOCK HAZARD—To avoid electrical shock hazards, do not
connect the light to the supply circuit when power is applied.
REVERSE POLARITY/MISWIRING—DC strobe units are
polarity- and voltage-sensitive and may be damaged by an
incorrect electrical hookup. When connecting the 24 Vdc
strobe unit to the voltage supply lines, polarity must be
observed. In addition, damage will result if the voltage rating
of the particular model is exceeded.
See the figures on pages 6 and 7. To wire the DC beacon to the
fixture terminal block:
1. Connect the positive (+) power source wire to the terminal
block screw marked L+.
2. Connect the negative (-) power source wire to the terminal
block screw marked N-.
3. If required by local building codes, connect the earth ground
wire to the green screw in the fixture mount.
4. Place the terminal block in the fixture mount and secure it with
the mounting screws.
5. Plug unused conduit entries with the provided close-up plugs.
6. To prevent galling and ease future maintenance, ensure that the
fixture mount threads are clean and lubricated.
7. Thread the fixture clockwise into the fixture mount and hand
tighten it securely.
