Description and Operation
1.1
Introduction
Welcome to the ICAM IFT-P Product Guide. This document is written to provide you with information on
technical specifications, cabling, and how to install, configure and operate the ICAM IFT-P detector.
The ICAM IFT-P is an aspirating smoke detector that provides early warning of fire by analyzing air drawn
through an air sampling pipe network. A highly sensitive detector chamber is able to detect smoke at very low
concentrations.

Principle of Operation
Air samples are drawn through the pipe network from the protected area through wide bore pipe systems.
Wide bore tubes generally have sampling holes drilled at intervals within the protected area.
The aspirator draws air from the pipe network into the detector inlets where the samples are combined,
filtered, and directed to the laser detection chamber. The ICAM IFT-P uses a T-piece of pipe to combine air
sampled from two inlet pipes.
The ICAM IFT-P has flow monitoring on both pipes. The detection chamber consists of a laser beam directed
across an optical chamber, through which the air sample flows. A photodetector built into the optical chamber
measures the amount of light scattering from particles in the air. A clean air sample will cause very little
scattering but as the smoke density of the sample increases, the amount of light directed onto the
photodetector will also increase. The light signal is processed to become a direct measurement of the amount
of light scatter caused by smoke. Information about laser chamber safety can be found on page .
If the smoke detected is higher than the preset alarm thresholds in the detector (Alert, Action, Fire 1 and Fire
2), an alarm will be reported. One or more Alarm relays, preset to activate at an alarm threshold will signal the
host panel after a preset time delay. The time delays can be changed as required. Alarm states are also
shown on the display panel.
