Introduction
Telefire's TFO-480A Analog Addressable Photoelectric Smoke Detector is an advanced
detector that offers the following advantages:
•
It is considered “green” (environment friendly) as it does not contain radioactive
materials.
•
The TFO-480A contains a powerful microprocessor that performs initial signal
processing locally. The final processing and decision making is performed by the
control panel.
•
The TFO-480A's microprocessor offers a high level of noise immunity and
interactively performs with the control panel drift compensation in order to overcome
environmental changes and dust accumulation in the chamber. Once the detector is
no longer able to compensate the control panel will display a trouble signal
requesting cleaning. The microprocessor also performs signal processing, enables
accurate control of the photoelectric chamber according to parameters set at the
control panel, and manages the communication process with the control panel.
•
The TFO-480A detector excels in sensing smoldering smoke and smoke from
burning of various materials.
•
Soft-set address – the detector’s address is programmed into its memory without
the use of mechanical switches or moving parts.
•
Can be tested directly with a test magnet or remotely from the control panel.
•
The detectors chamber and labyrinth can be cleaned in the field by authorized
people.
The detector consists of a vented chamber (labyrinth), an infrared transmitter and a
receiver that detects light scattering from the smoke particles in the chamber.
The sensitivity of the detector can be adjusted from the control panel within the range of
0.8% – 2.0%/foot (obscuration) in 0.2% increments. Please refer to the appropriate
control panel manual for details.
The detector contains an alarm LED that has 360° visibility. This LED flashes during
normal operation and is latched on during an alarm.
