Installation
WARNING
To reduce the risk of shock, always disconnect all power before handling the unit.
WARNING
To reduce the risk of shock, do not tamper with this device when the signal circuit is energized. Dis­connect all power and wait 5 minutes for stored energy to dissipate before handling.
1. Select a mounting method as detailed in Figure 1 and install the electrical box using suitable hardware.
a. For outdoor applications, install the weatherproof
box using four #10 x 1 1/4" (32 mm) screws and caplugs provided in the enclosed parts bag. Carefully adhere the gasket, part number P-007549­0082 (provided in the enclosed parts bag) to the box as shown in Figure 1.
NOTE: Be sure hook flange is facing outward as shown
in Figure 1.
NOTE: The designation "TOP" on boxes denotes
orientation of box after installation.
2. Attach mounting plate using two #8-32 screws provided with the surface box or four #8-32 screws provided with weatherproof box. The flush box uses two #8-32 screws (not provided).
3. Bring signaling circuit field wiring into electrical box.
4. Connect signaling circuit field wires to terminals on horn/strobe assembly (Figures 2-4).

pass through cutouts and engage with tabs on the mounting plate. With the bottom of the grille lifted out slightly, place the grille over the mounting plate so that the hinges of the grille
are in the mounting cutouts. b. Properly seat the grille by pressing the bottom in. c. Fasten the bottom of the grille to the mounting
plate by installing the captive combination drive
screw.
