Installation with PA400 Sounder
The optional strobes are interconnected to the PA400 by first
removing the two mounting screws from the sounder. Use a small
screwdriver to punch out the skinned-over areas as indicated in
Figure 2. Install the adapter plate on top of the sounder and screw
the combined sounder and adapter plate to the electrical outlet
box. Make sure field wiring terminals are oriented in the upward
position when mounted in the outlet box. Next, slide the strobe
directly into the slots in the plates. The positive solder lug may
be colored red or marked with a plus sign (+). This lug must be
in the slot closest to the field wiring terminals. Grasp the catch
area on each end of the strobe and squeeze while applying inward
force. Make sure the strobe catches fully engage the slots in the
adapter plate and that no gap appears at the interface between the
strobe and adapter plate.
