Finder FF O1000 Conventional Optical Smoke Detector

What Is the Finder FF O1000 Optical Smoke Detector?

The Finder FF O1000 is an optical smoke detector designed for use in conventional fire detection systems. It detects visible smoke particles produced in the early stages of a fire in enclosed spaces and alerts the conventional fire panel to which it is connected. It is highly sensitive to fires that develop slowly and begin as smouldering combustion.

Operating Principle

The device features an optical sensing chamber that operates on the light-scattering principle. Under normal conditions, the infrared emitter and receiver inside the chamber are positioned so that they cannot see each other. When smoke particles enter the sensing chamber, the infrared beam is scattered and reaches the receiver sensor. When the light intensity detected by the sensor exceeds the set threshold, the detector enters the alarm state and notifies the panel via the conventional zone line by drawing more current.

The Role of Fire Detection Systems

Optical smoke detectors are among the most fundamental components of fire safety systems, providing early warning. Detecting smoke produced by a fire before it reaches the flaming stage provides critical time to evacuate the area and organise the necessary response.

Why Choose It?

• Stable Detection: The advanced optical chamber design minimises false alarms caused by environmental factors.

• Easy Maintenance and Cleaning: The removable optical chamber makes routine cleaning and maintenance straightforward.

• 360-Degree Viewing Angle: The status LEDs on the device make it easy to check the detector's operating or alarm status from any angle.

• Broad Compatibility: It has a flexible design that works with many standard conventional fire alarm panels.

Installation Details

The Finder FF O1000 is easily installed by fitting it into a compatible conventional detector base. Its snap-fit locking mechanism makes installation and removal quick. For ceiling mounting, it is recommended that the detector be positioned centrally in the area, away from the outlets of ventilation ducts where air circulation is strong. End-of-line resistor connections must be made in accordance with the panel specifications.

Frequently Asked Questions

Can the Finder FF O1000 be used with addressable panels? No. The FF O1000 is a conventional detector. It is compatible with conventional fire alarm panels that operate on a zone basis.

How is the detector reset after it enters the alarm state? In conventional systems, the detector must be reset via the “Reset” function on the connected fire alarm control panel to clear the alarm state.
