The ICAM ILQ detector is a cost-effective Aspirated Smoke Detection (ASD) solution that meets the unique needs of numerous small area applications of up to 100 m² (1,000 ft²). Examples of these include telco landline remote offices, base station controllers, remote base stations, small server rooms, data centre containers, critical equipment, packaged HVAC units, anechoic chambers, pump houses, generator enclosures, signalling huts and modular laboratories, just to name a few.
ILQ detectors are suitable for both high and normal sensitivity applications and offer many installation advantages in terms of out-of-box operation, stand-alone functionality and simplified pipe network.

How it Works

The ILQ detector actively draws air from the protected area through a pipe network where two or four holes are used. The ILQ has two pipe inlets and there are always one or two holes on each pipe. Sampled air is then filtered before being analyzed by the detection chamber. The detection chamber utilizes a laser light source and photoelectric receiver circuitry to detect scattered light caused by the presence of smoke. Alarm (Pre-Alarm & Fire) and Fault conditions are reported by activating the corresponding LEDs on the simple display and dry contact relays. The system allows configuration of both smoke alarm and flow fault thresholds to suit the application needs.

Configuration Options

Convenient and expedient configuration of the ILQ detector is available via DIP switches for true out-of-box operation. A USB communication interface is also available for the Xtralis QSC Configuration and Fire System Management Software application.

Inputs and Outputs

The ILQ detector provides a programmable General Purpose Input (GPI) for remote Reset, Reset + Disable, Stand-by and External Device (PSU) monitoring functions. Three dry contact relay outputs are available for Alarm and Fault annunciation.
