6. Setup and Installation

Proper installation is crucial for the reliable operation of the horn strobe. Refer to the specific installation instructions provided with the product packaging for detailed diagrams and wiring schematics. The following is a general guide.

6.1 Mounting

1. Select Location: Choose a wall-mount location that complies with local codes and provides optimal visibility and audibility. Ensure the surface is flat and secure.
2. Prepare Mounting Box: Install a suitable electrical box (e.g., a 4-inch square box with an extension ring, or a weather-resistant outdoor box) according to local codes.
3. Attach Mounting Plate: Secure the device's mounting plate to the electrical box. Ensure the plate is oriented correctly for the desired device position.
4. Weather Sealing: As the device is NEMA 4X and IP56 rated, additional caulk or sealant on the backbox is generally not required, simplifying installation. However, ensure the mounting surface is flush and the device gasket creates a proper seal.

6.2 Wiring

1. Disconnect Power: Ensure all power to the Notification Appliance Circuit (NAC) is disconnected before wiring.
2. Connect Wires: Route the NAC wiring through the electrical box. Connect the positive and negative wires from the NAC to the corresponding terminals on the horn strobe. Refer to the product's specific wiring diagram for terminal identification and proper polarity.
3. Candela Setting: Adjust the candela setting switch on the device to the desired output level as required by local codes and system design.
4. Secure Device: Once wiring is complete and verified, carefully attach the horn strobe unit to the mounting plate, ensuring it snaps or screws securely into place.
5. Restore Power and Test: After installation, restore power to the NAC and perform a functional test of the horn strobe in accordance with NFPA 72 and local requirements.

7. Operating Instructions

The System Sensor P2GRKLED L-Series Horn Strobe operates as part of a fire alarm control panel (FACP) system. It is designed to activate automatically upon receiving a signal from the FACP.

• Activation: When the FACP detects a fire condition or other emergency, it sends a signal to the NAC, which in turn activates the horn strobe.
• Audible Alert: The horn will sound a distinct alarm tone to alert occupants.
• Visual Alert: The LED strobe light will flash at a specified candela intensity to provide a visual warning, particularly important for individuals with hearing impairments or in noisy environments.
• Deactivation: The horn strobe will deactivate once the alarm condition is cleared and the FACP is reset.

8. Maintenance

Regular maintenance ensures the continued reliable operation of your System Sensor P2GRKLED horn strobe.

• Routine Inspection: Visually inspect the device periodically for any signs of damage, discoloration, or obstruction. Ensure the lens is clear and free of debris.
• Cleaning: If cleaning is necessary, gently wipe the exterior with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the finish or lens.
• Functional Testing: Conduct periodic functional tests of the horn strobe as recommended by NFPA 72 and local fire codes. This typically involves activating the fire alarm system to ensure the horn sounds and the strobe flashes correctly.
• Professional Servicing: Any repairs or internal servicing should only be performed by qualified fire alarm technicians.
