4. Setup and Installation

The PAD 200-DUCT is designed for ceiling mount installation within HVAC duct systems. Proper air sampling tube installation is critical for effective smoke detection.

4.1 Site Selection

• Select a location in the duct where airflow is consistent and turbulence is minimal.
• Ensure easy access for maintenance and testing.
• Avoid locations immediately downstream from humidifiers, filters, or sharp bends in the ductwork.

4.2 Mounting the Detector

1. Turn off all power to the HVAC system and the detector's power supply.
2. Drill appropriate holes in the ductwork for the detector housing and air sampling tubes according to the provided template (if applicable).
3. Secure the detector housing to the duct using the supplied mounting hardware. Ensure a tight seal to prevent air leakage.
4. Install the air sampling tubes. The inlet tube should extend across the duct to sample the entire airflow, and the exhaust tube should be shorter.

4.3 Wiring

The detector operates on 9 Volts DC (Battery Powered). Refer to the wiring diagram on the unit or in supplementary documentation for specific connections. Ensure correct polarity and secure all connections.

• Connect the power supply wires to the designated terminals.
• Connect alarm and supervisory contacts to the fire alarm control panel as required by local codes.

5. Operating Instructions

Once installed and powered, the PAD 200-DUCT detector continuously monitors the air within the HVAC duct for the presence of smoke particles.

5.1 Normal Operation

Under normal conditions, the detector's status indicator (usually an LED) will flash periodically, indicating that the unit is powered and functioning correctly. The detector is in a standby state, ready to detect smoke.

5.2 Alarm Condition

When smoke is detected in the duct, the detector will enter an alarm state. This will trigger an audible alarm from the unit itself and activate its alarm contacts, signaling the fire alarm control panel. The status indicator will typically illuminate steadily or flash rapidly to indicate an alarm.

5.3 Resetting the Detector

After an alarm condition has been addressed and the smoke cleared, the detector can be reset. This is typically done via the fire alarm control panel or a local reset button on the detector itself (if present). Refer to your fire alarm system documentation for specific reset procedures.

6. Maintenance

Regular maintenance ensures the continued reliability and performance of your duct detector.

6.1 Testing

• Monthly: Perform a functional test using the test button on the detector. This should trigger an alarm.
• Annually: Conduct a full system test with simulated smoke to ensure the detector responds correctly and communicates with the fire alarm control panel. This should be performed by a qualified technician.

6.2 Cleaning

• Annually (or as needed): Carefully remove the detector head and clean the sensing chamber using a soft brush or compressed air to remove dust and debris.
• Clean the exterior of the detector housing with a damp cloth. Do not use harsh chemicals or abrasives.
• Inspect air sampling tubes for blockages or damage.

6.3 Battery Replacement

The detector is battery-powered (9 Volts DC). Replace the battery annually or immediately if a low battery signal is indicated by the detector or the fire alarm control panel. Use only recommended battery types.

1. Disconnect power to the detector.
2. Open the detector housing.
3. Carefully remove the old battery and dispose of it according to local regulations.
4. Insert a new 9V DC battery, ensuring correct polarity.
5. Close the housing and restore power. Test the detector.

7. Troubleshooting

If troubleshooting steps do not resolve the issue, contact qualified service personnel.
