Notification Appliances—E Series Speakers and Strobe Speakers 13
Refer to Figures 2 through 4 when installing units. Use mounting
Option B for E-9025 and E-9070 models. Use mounting Option A or C for E-7025 and
E-7070 models. Order plates and backboxes separately. Special plates and backboxes
are indicated in the illustrations and described in Table 9, located in the Mounting
Accessories section
Mounting hardware is included for each mounting option. You can fill the two unused
mounting holes using the short screws and retaining nuts (provided in the hardware bag)
prior to mounting the device to the backbox.
Note:
The models are illustrated with the optional strobe.
!
CAUTION:
Equipment damage hazard. The National Electrical Code
(NEC) Article 370-6 limits the maximum number of
conductors that can enter a backbox based on the size of the
backbox and the size of the wiring used. Johnson Controls
recommends that you adhere to the conductor limitations
shown in the tables following each mounting option.
Johnson Controls also recommends that you use a 2-1/8 inch deep extension ring added to
the 4 inch square backbox where possible to provide additional wiring room for easy
installation.
!
CAUTION:
Equipment damage hazard. The mounting methods
described in this document are only applicable within the
continental United States. Extension rings provided outside
of the United States may not meet the required specifications
for successful mounting purposes and may damage your
speakers. Consult Wheelock, Inc. for appropriate mounting
instructions in countries other than the United States.
General mounting instructions:
1.
Select the largest backbox possible to provide additional wiring room for easy
installation (Figures 3 through 5).
2.
Select the conduit entrance to backboxes to ensure sufficient wiring clearance for
installed equipment. When extension rings are required, enter the conduit through
the backbox, not the extension ring. Use Steel City No. 53151 x 1-1/2 inch deep or
No. 53171 x 2-1/8 inch deep extension rings or the equivalent with same area cut
out in back.
Note:
If a sheathed multiconductor cable or 3/4 inch conduit fitting is used, check that
the installed product has sufficient clearance and wiring room prior to installing
the backboxes and conduit.
!
CAUTION:
Equipment damage hazard. Check the installation
instructions of the manufacturers of other equipment used in
the system for any guidelines or restrictions on wiring and/or
locating signaling circuits and signaling devices.
