NOTIFIER FS-OSI-RI Adressable Beam Detector User Manual

1. Introduction

This manual provides essential information for the proper installation, operation, and maintenance of the NOTIFIER FS-OSI-RI Adressable Beam Detector. The FS-OSI-RI is a sophisticated fire safety device designed to detect smoke over large areas by projecting and receiving an infrared beam. It is an integral component of an addressable fire alarm system, providing reliable early warning capabilities.

2. Safety Information

Read all instructions carefully before installation and operation. This device must be installed by qualified personnel in accordance with all local and national electrical and fire codes. Disconnect power before servicing. Failure to follow these instructions may result in property damage, injury, or death. Regular testing and maintenance are crucial for optimal performance.

3. Setup

3.1 Unpacking

Carefully remove the beam detector and its components from the packaging. Inspect all items for any signs of damage. Report any damage to your supplier immediately. Retain packaging for future transport or storage.

3.2 Mounting

The FS-OSI-RI consists of a transmitter/receiver unit and a reflector. Mount the transmitter/receiver unit and the reflector on a stable surface, ensuring they are aligned and within the specified operating distance. Refer to the detailed mounting diagrams provided in the separate installation guide for precise placement and alignment procedures. Ensure the mounting location is free from obstructions and excessive vibration.

3.3 Wiring

Connect the detector to the addressable fire alarm control panel (FACP) using appropriate wiring methods as specified in the FACP manual and local codes. Ensure correct polarity and secure all connections. The device operates on a low-voltage power source provided by the FACP.

3.4 Initial Power-Up and Addressing

After all wiring is complete and verified, apply power to the FACP. The detector will perform a self-test. Set the unique address for the FS-OSI-RI using the addressing mechanism on the device, following the FACP's programming instructions. Proper addressing is critical for the FACP to identify the detector's location and status.

4. Operating

4.1 Basic Functionality

The FS-OSI-RI continuously monitors the infrared beam path between its transmitter/receiver unit and the reflector. When smoke enters the beam path, it obscures the beam, causing a reduction in the received signal. If the signal reduction exceeds a pre-set threshold for a specified duration, the detector will signal an alarm condition to the FACP.

4.2 Status Indicators

The detector features LED indicators to communicate its operational status:

• Green LED: Indicates normal operation.
• Red LED: Indicates an alarm condition.
• Yellow LED: Indicates a trouble condition (e.g., beam blockage, misalignment, fault).

4.3 System Integration

As an addressable device, the FS-OSI-RI communicates its status directly to the FACP, allowing for precise identification of the alarm or trouble source. The FACP will then initiate appropriate responses, such as activating alarms, notifying emergency services, or displaying the event location.

5. Maintenance

5.1 Cleaning

Periodically inspect the detector's lens and the reflector for dust, dirt, or other obstructions. Clean these surfaces using a soft, lint-free cloth. For stubborn dirt, a mild, non-abrasive cleaning solution may be used, applied to the cloth, not directly to the device. Ensure the device is powered down before cleaning.

5.2 Testing Procedures

Regular functional testing is essential. Perform tests in accordance with NFPA 72 and local authority having jurisdiction (AHJ) requirements. Testing typically involves:

• Smoke Obscuration Test: Introduce an approved test smoke into the beam path to verify alarm activation.
• Alignment Check: Verify proper beam alignment using the detector's alignment indicators or a dedicated alignment tool.
• Sensitivity Test: If applicable, verify the detector's sensitivity settings are within acceptable ranges.

5.3 Battery Replacement

While the primary power source is typically wired, some systems may incorporate backup batteries. If your system includes a battery backup for the detector or its associated control module, ensure batteries are replaced according to the manufacturer's recommendations or when a low battery trouble signal is indicated by the FACP.

6. Troubleshooting

Refer to the FACP manual for specific trouble codes and detailed troubleshooting steps. Below are general troubleshooting guidelines:

• False Alarms: Check for environmental factors such as dust, steam, insects, or direct sunlight interfering with the beam path. Verify proper alignment and cleanliness of the lens and reflector.
• No Detection: Ensure the detector is powered, correctly addressed, and properly aligned. Check for complete beam obstruction or damage to the unit/reflector.
• Trouble Signal (Yellow LED): This often indicates a beam blockage, misalignment, or a fault within the unit. Re-align the beam, clean the optics, and check wiring connections. If the issue persists, contact technical support.
• Communication Errors: Verify wiring integrity between the detector and the FACP. Check the detector's address setting.
