[1] The trim skirt is outdoor-rated when used with the 449 weatherproof box.

Synchronized operation requires a separately installed synchronization control module. See Table 3 on page 3 for a list of compatible synchronization sources.

Installation

Install this appliance in accordance with the latest edition of NFPA 72 and the local authority having jurisdiction.

WARNING: Electrocution hazard. To avoid personal injury or death from electrocution, remove all sources of power and allow stored energy to discharge before installing or removing equipment.

Caution: Electrical supervision requires the wire run to be broken at each terminal. Do not loop the signaling circuit field wires around the terminals.

Note: The Genesis WG4 High-Candela Speaker-Strobe may be ceiling-mounted or wall-mounted and may be placed in one of four positions (strobe above, strobe below, and strobe to either side); place the electrical box accordingly. See Figure 4.

To install the speaker-strobe:

• 1. Remove the cover from the speaker-strobe by first removing the six cover screws. See Figure 1 on page 2.
• 2. If desired, place the optional trim skirt over the electrical box. See "Specifications" for a list of compatible boxes.

• 3. Remove the gasket that comes with the 449 weatherproof box and replace it with the gasket that comes with the WG4 speaker-strobe.
• 4. Place the gasket over the backplate, and then feed the field wiring through the wire slots on the gasket and the backplate. See Figure 5, item 3.
• 5. Secure the backplate to the electrical box with four screws.
• 6. Connect the wiring to the terminal strip.
• 7. Connect the speaker to the audio NAC and the strobe to the strobe NAC. Observe polarity. See Figure 5.
• 8. If temporal strobe (private mode) operation is desired, cut jumper JP1. See Figure 5, item 5.
• 9. Set the speaker voltage.

The default speaker voltage is 70 V. For 25 V, reposition the speaker voltage-setting switch S3. See Figure 5, item 4.

10. Set the candela output.

The default candela setting is D. To select a different candela output, align the S2 indicator to the desired candela output. See Table 5 and Figure 5, item 1.

• 11. The default wattage setting is Z, corresponding to 1/4 watt. To select a different wattage, align the S1 indicator to the desired wattage setting. See Table 4 and Figure 5, item 2.
• 12. Remove the strobe protective cover. See Figure 2.
• 13. Position the cover over the backplate and secure with the six cover screws.
• 14. Test the unit for proper operation.
