Xtralis ICAM ILS-2 Aspirating Smoke Detector

Key Features
EN54-20 approved
Economical, single or dual area aspirated 'fire' detection
1 or 2 sampling pipes - each up to 100m in length
Coverage up to 1,500m2 at class C
3 users configurable alarm levels per channel


The XTRALIS ICAM ILS-2 Aspirating Smoke Detector provides laser air-sampling smoke detection to meet the individual requirements of many industrial and commercial applications. ICAM ILS-2 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 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.

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.

Programming and Diagnostics

ICAM ILS-2 Detectors have three alarm levels. The sensitivity threshold for each alarm level, along with fan speed and flow sensitivity, can be individually programmed. ILS-2 detectors can be configured using a PC via its USB interface or can be figured locally using an integrated programing interface.
