ICAM IAS Single Or Dual Channel Air-Sampling Smoke Detector
Summary
The ICAM IAS Air-sampling Smoke Detection systems provide a flexible solution to meet the unique needs of numerous applications including industrial spaces such as cable tunnels, tamper-proof and unobtrusive requirements of special accommodation, or can simply be used to replace spot (point) detectors in office environments. Available in single inlet pipe (IAS-1) or dual inlet pipe (IAS-2) configurations, these systems offer versatile detection capabilities.
These systems actively draw air from the protected area through sampling holes in a pipe network, with sampled air filtered before being analysed by conventional or analog point detectors incorporated within the systems. The IAS utilises a high performance aspirator and software configurable flow monitoring circuitry, with air flow level displayed on a ten element bar graph that can be adjusted for high and low flow thresholds. The installer-specifiable point detectors offer benefits in simplicity of configuration and cost effectiveness, making integration with existing fire alarm systems straightforward.

FAQ
What is the difference between IAS-1 and IAS-2 systems?
The IAS-1 system features one inlet pipe and can accommodate one or two spot detectors, whilst the IAS-2 system features two inlet pipes and accommodates two spot detectors. Both systems support multiple detection strategies when fitted with two detectors.
What types of point detectors can be used with the IAS systems?
The IAS systems support 1 or 2 analog addressable or conventional spot detectors, including a variety of detector technology types such as photoelectric, ionisation, heat, CO, and others from leading technology providers. Detectors must have universal screw mounting.
What detection strategies are available?
The IAS systems can be configured for single or dual addressable area detection, redundant detection, multi-criteria detection, and coincident or double-knock detection. The specific strategy depends on the number of detectors fitted and boolean logic configuration.
What is the maximum sampling pipe length?
Each inlet pipe can accommodate up to 100 m (328 ft) of sampling pipe. Pipe length may vary subject to specifications by local codes and standards.
How is airflow monitored in the IAS systems?
The systems utilise software configurable flow monitoring circuitry with air flow level displayed on a ten element bar graph. High and low flow thresholds are adjustable, and flow failure is reported as a device fault via relays to the loop.
What are the power requirements?
The IAS systems operate on 24 VDC nominal (18 to 30 VDC) supply voltage with maximum current consumption of 300 mA. Note that spot detectors are powered from the signalling circuit.
Can the IAS systems integrate with existing fire alarm panels?
Yes, in circumstances where premises are already protected by point detectors, the IAS system can be easily introduced onto the existing fire alarm control panel signalling circuit by fitting equivalent detectors into the system, subject to IAS system approval for the fitted detector.
