The XTRALIS ICAM ILS Aspirating Smoke Detector provides laser air-sampling smoke detection to meet the individual requirements of many industrial and commercial applications. ICAM ILS detectors are suitable for both medium sensitivity and multi-hole Class C applications.

These detectors are compact, rugged, waterproof and extremely versatile making them suitable for both general coverage and localised protection of equipment cabinets or ductwork.

The ICAM ILS-2 system has one and two inlet pipes and can be configured with dual addressable areas.

Each detector has two sets of alarm contacts per channel which are programmable across the dynamic sensitivity range of 0.06 to 3.33% per meter in 9 stages. The detectors internal fan is powerful and quiet and can support pipe lengths of up to 100m per channel.

Pipe Lengths

The ICAM ILS is equipped with a powerful aspirator that enables use of a total of 100m (linear) of sampling pipe per inlet.

Class Sensitivity

Maximum number of holes per EN54-20 sensitivity class:

Class A3 holes per inlet
Class B6 holes per inlet
Class C18 holes per inlet

How It Works

ICAM ILS Aspirating Smoke Detectors actively draw air via sampling a network of pipes. The air is filtered before being analysed by medium sensitivity laser spot (point) detectors that are incorporated into the system. Alert, Action or Fire alarm states are communicated through dry contact relays and indicated via LEDs on the detector’s display.

ILS detectors employ a powerful, high-performance aspirator and sophisticated, software configurable, flow monitoring circuitry. The system features a ten element bar graph display that can be adjusted for low and high flow thresholds. Flow failure is reported as a device fault via dedicated fault relays.

Configuration Options & Detection Strategies

The ILS system is available with one inlet pipe (ILS-1) or two inlet pipes (ILS-2), and can be fitted with one or two detectors per system. The available options for the ILS-1 and ILS-2 systems are:

  • ILS-1 system – one or two laser point (spot) detectors *
  • ILS-2 system – two laser point (spot) detectors

ILS-1 systems fitted with one laser point detector are capable of providing single area detection, but ILS-1 and ILS-2 systems fitted with two detectors can be configured for a number of detection strategies. The table below describes the possible detection strategies for ILS systems fitted with two point detectors:

ILS-1Single Addressable Area
Redundancy *
Coincident / Double-Knock * †
ILS-2Dual Addressable Areas

* These are software programmable modes for an ILS-1 system fitted with two detectors (second detector sold separately).

† Subject to local codes and standards.

Programming and Diagnostics

ICAM ILS detectors have three alarm levels. The sensitivity threshold for each alarm level, along with fan speed and flow sensitivity, can be individually programmed. ILS detectors can be configured locally using an integrated programming interface or configured and diagnosed via the well known Xtralis VSC software via its USB interface.


The ICAM ILS is fully approved by VdS for safe use and installation in any European Union country and bears the CE mark to show that it complies with all the applicable Directives including the CPR, EMC and the Low Voltage Directive (LVD).
