Installation

A qualified electrician familiar with National Electrical Code and local code requirements must install this product. Failure to follow the safety precautions in this instruction sheet could result in product or property damage, severe personal injury or death.

WARNING

To reduce the risk of shock, do not connect AC power until installation is complete.

• 1. Install Cat. No. 6537 Pull Cord Switch (Figures 1 and 2).
  • a. Install a single gang 2" x 4" (51 mm x 102 mm) electrical box using suitable hardware.
  • b. Extend the black and white wires using 18 AWG wire and connectors (not supplied). Route the extended wires to the horn/strobe and transformer (polarity is not important). Ground in accordance with local codes and regulations.
  • c. Mount the pull cord switch onto the electrical box using two screws (supplied).
• 2. Install Catalog No. 6536-G5 horn/strobe (Figures 1 and 4).

WARNING

To reduce the risk of shock, do not remove lens or tamper with unit when the circuit is energized. Disconnect power and allow five (5) minutes for stored energy to dissipate before starting work or disassembly. High energy could be stored in the strobe circuit once it is energized.

The 6536-G5 horn/strobe can be mounted on any single gang 2" x 4" (51 mm x 102 mm) electrical box, double gang 4" x 4"

(102 mm x 102 mm) electrical box, or standard 4" x 4" (102 mm x 102 mm) junction box with a plaster ring.

• Install an appropriate electrical box using suitable hardware.
• b. Connect one wire from the 6537 pull cord to one of the horn/strobe wires (polarity is not important).
• c. Extend the remaining horn/strobe wire to the transformer.
• d. Mount the horn/strobe onto the electrical box using two screws (supplied).
• 3. Install Catalog No. 592 Transformer (Figures 1 and 3).
  • a. Select a metal electrical box that can be grounded. Mount the transformer onto the electrical box (Figure 3) so that it has ground continuity to the box and conduit system.
  • b. Install the box using suitable hardware.
  • Ground the box in accordance with local codes and regulations.
  • d. Connect the remaining pull cord switch wire to one of the terminals marked 24V 20VA.
  • e. Connect the horn/strobe wire to the second terminal marked 24V 20VA.
  • f. Connect the transformer's primary wire leads to an appropriate 120V AC power source.
• 4. When all connections are completed, pull the cord switch and verify operability of the horn/strobe.
