1. Attach the speaker strobe expander plate to the junction box as shown in
Figure 5. The speaker strobe expander plate is compatible with a 4˝ x 4˝

˝ junction box. If using a back box skirt, attach the speaker strobe
expander plate to the back box skirt and then attach the entire assembly
to the junction box (see figure 6).
2. Connect the field wiring to the terminals, as shown in Figure 1.
3. If the speaker strobe device is not to be installed at this point, use the
paint cover to prevent contamination of the speaker strobe expander
plate.
4. To attach the speaker strobe device to the speaker strobe expander plate,
remove the paint cover, then hook the tabs on the product housing into
the grooves on the strobe plate.
5. Swing the speaker strobe device into position to engage the pins on the
device with the terminals on the speaker strobe expander plate. Make
sure that the tabs on the back of the device housing fully engage with the
expander plate.
6. Secure the speaker strobe device by tightening the single mounting
screw in the front of the speaker strobe housing. For tamper resistance,
the standard captive mounting screw may be replaced with the enclosed
Torx screw.

NOTE: The total number of strobes on a single NAC must not exceed 40 for
24 volt applications or 12 for 12 volt applications. Loop resistance on a single
NAC should not exceed 120 ohms for 24 volt and 30 ohms for 12 volt systems.
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.

NOTE: UL1971 is not applicable to mass notification devices, but these read-
ings were obtained using the measurement procedure specified under UL1971.
IMPORTANT: For more information on current draw, light output and sound
output data, reference Speaker Strobe installation manual I56-3935 and Strobe
only installation manual I56-2769.
NOTE: Shorting springs are provided between terminals 2 and 3 and terminals
5 and 6 of the mounting plate to enable wiring checks after the system has
been wired, but prior to installation of the final product. These springs will
automatically disengage when the product is installed, to enable supervision
of the final system.
