SL-2000-P Duct Smoke Detector by APC By Apollo

1. Why is the SL-2000-P the top choice in Vietnam?

APC by Apollo is a US-based brand renowned worldwide for its smart fire detection solutions. The SL-2000-P is specially designed for the Asian market, offering internationally certified safety and quality (UL & CUL, CSFM) at a more competitive price.

SL-2000-P Duct Smoke Detector

This detector features:

• Photoelectric sensing – for fast smoke detection.
• Combined heat and smoke sensing – to enhance sensitivity while minimizing false alarms.
• Compatibility with both local and zoned fire alarm systems.

2. A Critical Role in Building Fire Protection Systems

🔸 Early Fire Detection – A Lifesaving Factor
As the first line of defense in fire safety, the SL-2000-P quickly detects smoke within seconds, enabling:

• Timely evacuation of occupants and staff.
• Automatic activation of alarms, lights, and fire suppression systems (e.g., sprinklers, gas).
• Signal transmission to the control panel for responsive actions.

🔸 Minimizing Damage and Risk
Early warning and response help:

• Prevent the spread of fire throughout the building.
• Protect assets, documents, and equipment in offices and factories.
• Reduce legal risks for building owners and managers.

🔸 Smart Integration with Building Management Systems (BMS)
APC smoke detectors integrate with BMS via addressable signals, allowing:

• Real-time monitoring of device status.
• Quick localization of the fire zone for precise emergency response.
• Automatic control of elevators, fire doors, and pressurization fans.

3. Key Features of the SL-2000-P

🔸 Flexible Output Signals
Supports both addressable and conventional systems with separate output terminals:

• Terminals 6 & 7: Fire alarm relay contacts (NO/NC).
• Terminal 12: Activates the “Common Shutdown” output – used to shut off HVAC during fire.
• Terminals 13 & 14: Technical fault relay (for error or power loss conditions).

🔸 Supports up to 30 devices on a single shutdown loop
🔸 Built-in LED Status Indicators
Easily check the status – power, alarm, fault, or maintenance needed.

🔸 Magnet Test Function
Hold a magnet to the designated area on the detector cover to simulate a fire alarm. The red LED lights up and output current increases, verifying system response.

4. Installation & Operation Guide for SL-2000-P

Step 1: Choose the Right Location

• Mount on horizontal ductwork where airflow is stable, away from bends, dampers, or fans.
• Ideal placement: at least 3 duct diameters before and after the sampling point.

Step 2: Install Sampling Tubes

• Adjustable to match airflow direction.
• Ensure red plug caps the intake tube (for smoke entry); blue cap on exhaust tube (for flow exit).

Step 3: Electrical Connections

• Power with 24VDC or 120/220VAC.
• Connect relay terminals according to fire alarm system diagram.
• For HVAC shutdown: Terminal 12 to control device; Terminal 20 supplies +24VDC.

Step 4: Test and Maintain

• Use a magnet to verify fire alarm function.
• Check fault LED to know when cleaning is needed.
• Regularly clean the fan, filter, and sensor to maintain performance.
