3. Installation

3.1 Unpacking and Inspection

Carefully unpack the PC2-WL Horn Strobe and inspect it for any signs of shipping damage. Verify that all components, including the mounting plate, are present. If any damage is found or parts are missing, contact your supplier immediately.

3.2 Mounting Location

The PC2-WL is designed for ceiling mounting. Select a location that provides optimal audibility and visibility within the protected area, adhering to local codes and standards for notification appliance placement.

3.3 Wiring

Connect the device to the fire alarm control panel's notification appliance circuit (NAC) terminals. Ensure correct polarity. The device operates on 12/24V DC. Refer to the fire alarm control panel's documentation for specific wiring diagrams and compatibility.

3.4 Device Assembly and Mounting

Secure the provided mounting plate to the ceiling junction box using appropriate hardware.
Connect the wiring from the NAC to the terminals on the horn strobe unit.

4. Operating Instructions

The System Sensor PC2-WL Horn Strobe operates automatically in conjunction with a compatible fire alarm control panel. When the fire alarm panel detects an alarm condition, it will activate the horn strobe.

Horn Function: Upon activation, the device will emit an audible alarm signal with a peak output of 90 dBA.
Strobe Function: Simultaneously, the integrated strobe light will flash at a specified candela rating (15/177 candela), providing a visual alert.

The device remains in standby mode with 0 mA current draw until an alarm condition is detected. During an alarm state, the current draw ranges from 54 to 289 mA, depending on the selected candela setting and voltage.

5. Maintenance

Regular maintenance ensures the continued reliable operation of your PC2-WL Horn Strobe.

Cleaning: Periodically clean the exterior of the device with a soft, dry cloth to remove dust and debris. Do not use abrasive cleaners or solvents.
Testing: Conduct functional tests of the horn and strobe as part of your regular fire alarm system testing schedule, as required by local codes and NFPA 72.
Inspection: Visually inspect the device for any physical damage, discoloration, or obstructions to the horn or strobe.
Power Cycle: If the device appears to be malfunctioning, ensure power is disconnected from the fire alarm panel, wait a few minutes, and then restore power. If the issue persists, refer to the troubleshooting section.

6. Troubleshooting

Problem	Possible Cause	Solution
Horn or Strobe not activating during alarm.	No power from NAC. Incorrect wiring. Device malfunction.	Verify power to the NAC from the fire alarm panel. Check wiring connections for correct polarity and secure terminals. Consult a qualified technician for device replacement if necessary.
