Genesis Low Frequency (520 Hz) Horn Installation Sheet

Description

The Genesis Low Frequency (520 Hz) horn can be used for applications where a low frequency alarm notification appliance is required. The device is designed for indoor use only and can be mounted on the wall or ceiling. See Table 1 for a list of model numbers.

The horn includes field-configurable jumper options for selecting:

• Temporal or steady horn output
• High dB or low dB output

Installation

Install and wire this device in accordance with applicable national and local codes, ordinances, and regulations.

Note: Electrical supervision requires that you break the wire run at each terminal. Do not loop wires around the terminals.

To install the horn:

• 1. Remove the cover by using a screwdriver to depress and slightly twist both tabs on top of the unit.
• 2. Set the horn signal and sound output level to desired settings. See Figure 1.

To change the horn output level from high dB to low dB, cut jumper JP3.

To change the horn signal from temporal to steady, cut jumper JP2.

3. Mount the horn as follows.

Note: Route the signal circuit field wiring through the cutout in the center of the horn.

Flush mount: Mount the horn and flush mount spacer onto a compatible electrical box (Figure 2), making sure not to overtighten the mounting screws. See "Specifications" for compatible electrical boxes.

Surface mount: Mount the G4B or G4RB surface mount box on the wall or ceiling (Figure 3), and then secure the appliance to the box using the screws provided with the box.

• 4. Connect the signal circuit field wiring to the horn terminals (Figure 4). Observe polarity for the unit to function properly.
• 5. Replace the cover by aligning it at the bottom, and then snapping it in at the top (Figure 2 and Figure 3).
• 6. Test the unit for proper operation.
