Installation

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.

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

Install this product in accordance with applicable requirements in the latest editions of NFPA 72 National Fire Alarm and Signaling Code, CSA C22.1 the Canadian Electrical Code, Part 1, Section 32, CAN/ULC-S524 Installation of Fire Alarm Systems, and in accordance with the local authority having jurisdiction.

To install the temporal horn:

• 1. Select and install a suitable electrical box. See "Mounting the electrical box" on page 2 for details.
  • Note: Outdoor installations require a weatherproof backbox.
• 2. Set the tone and pattern. See "Selecting the volume and pattern" on page 2 for details.
• 3. Bring the signal circuit field wiring into the electrical box.
• 4. Position the mounting plate on the electrical box with the hook flange up and facing outward as shown in Figure 2. Fasten the plate using the screws provided.
• 5. Connect the signal circuit field wiring. For the unit to function properly, observe polarity. See Figure 1.
  • For additional wiring details, see the installation instructions for the signaling modules or circuits used in the fire alarm control panel.
• 6. After completing the connections, attach the unit to the mounting plate, as noted below.
  • a. The grille has tabs (at the top of the inner face) that engage with the hook flange on the mounting plate. Angle the bottom of the grille out slightly, and then slide the unit into place so that the tabs engage the flange.
  • b. Seat the grille by pressing the bottom in.
  • c. Fasten the bottom of the grille to the mounting plate by tightening the captive locking screw.
• 7. Apply power and activate the unit to verify that it is operating properly.

Figure 1: Typical wiring diagram

Polarity is shown in the active state.

• (1) From UL/ULC Listed fire alarm control panel signal circuit.
• (2) To next device or end of line resistor for Class B. Return to control panel for Class A connection.

• (1) Gasket with adhesive backing
• (2) Weatherproof box
• (3) Standard box
• (4) Knockouts for 1/2 in. (13 mm) or 3/4 in. (19 mm) conduit top, bottom, back
• Mounting the electrical box

Figure 2 shows mounting details for:

• Standard box. When using a 4 in. square box, use an extension ring for additional wiring space, if needed. If using a double-gang electrical box that is 2-1/2 in. (64 mm) deep, locate the conduit only at the rear of the box.
• Weatherproof box. Peel off the adhesive backing from the gasket and adhere to the box.
• Surface mount box.

Selecting the volume and pattern

The horn has a jumper for selecting a high or low volume output level. The default is high volume. To set the output to low volume, remove the output jumper from the circuit board on the rear of the unit. See Figure 3.

The horn has a jumper for selecting either a temporal or steady tone. The default is temporal tone. To set the output to steady tone, remove the tone jumper from the circuit board on the rear of the unit. See Figure 3.

Tip: Save the jumper by sliding it onto a single pin.

  • (6) Mounting plate (supplied with horn)
  • (7) #8-32 screw
  • (8) Captive locking screw
  • (9) Hook flange
