NOTE: The total number of strobes on a single NAC must not exceed 69 for
24 volt applications. Loop resistance on a single NAC should not exceed 120
ohms for 24 volt.
NOTE: A shorting spring is provided between terminals 2 and 3 of the mount-
ing plate to enable wiring checks after the system has been wired, but prior
to installation of the final product. This spring will automatically disengage
when the product is installed, to enable supervision of the final system.
Removal of a notification device will result in an open circuit indication on
the NAC.
MOUNTING AND REMOVING APPLIANCE
1. Attach mounting plate to junction box. (See Figures 3, 5, 7, and 9.)
2. Connect field wiring to terminals. (See Figures 1 and 2.)
3. If the product is not to be installed at this point, use the paint cover to
prevent contamination of the mounting plate.

(See Figure 12.)
3. Threaded knockout holes are provided for the sides of the box for ¾ inch
and ½ inch conduit adapter. Knockout plugs in the back of the box can
be used for ¾ inch and ½ inch rear entry.
4. To remove the ½ inch or ¾ inch knockout, place the blade of a flat-head
screwdriver along the outer edge and work your way around the knock-
out as you strike the screwdriver. (See Figure 13.)
NOTE: Use caution not to strike the knockout near the top edge of the
surface mount back box.
5. V500 and V700 wiremold raceways are also provided. Use V500 for low
profile applications and V700 for high profile applications.
6. To remove the knockout, turn pliers up. (See Figure 13.)
7. Attach the mounting plate to the surface mount back box using the four
unpainted screws. (See Figures 4, 6, 8, and 10.)
8. To wire and attach the product, follow steps 4 and 5 of “Mounting and
