This document, the "ICAM Commissioning Guide," outlines the process for commissioning an ICAM (Intelligent Control and Monitoring) system. It is intended for individuals who have attended accredited ICAM training and are knowledgeable about the ICAM product range, aspirating smoke detection systems, and relevant local codes and standards. Commissioning involves integrating the pipe network design, detector installation, power and communication cabling, and system power-up to deliver a fully functional ICAM system that meets customer specifications.
The commissioning process is a systematic approach to validate all operational aspects of the ICAM system, benchmark performance levels, and generate necessary documentation for effective management and maintenance. It is divided into several stages:
This stage is split into two parts: tasks performed before visiting the customer site and tasks performed once on site. Before visiting the site, the commissioning engineer should gather and study design and installation records, including:
Once on site, the initial steps involve checking cabling and initial power-up. All electrical and ICAM network cabling must be securely terminated with correct polarity. The system should be connected to a 24 VDC power source. Caution: Reversing the supply or providing out-of-specification power can damage the ICAM system. All electrical installations must meet local electrical codes and standards. Data communication uses an RS 485 network (unidirectional), requiring correct polarity throughout. Belden 9841 (120 ohm) twisted pair cables (or similar) are recommended. Upon power-up, the system takes approximately 30 seconds to initialize. If any detector fails to power up, power connections and polarity should be re-checked. During power-up, different detectors exhibit specific behaviors:
A preliminary systems check using Xtralis VSC software should be conducted. Faults generated at power-up or due to site changes are normal and can be silenced by accepting factory defaults, but detectors must be configured to site requirements. Settings should be changed to suit site requirements, including normalizing airflow using Xtralis VSC or the display panel. A smoke test at the farthest sampling hole confirms the detector registers smoke within ASPIRE's anticipated time and local codes' maximum time, checking for blockages or leakages.
ICAM detectors (except IAS detectors) are recommended to be configured with Xtralis VSC software. If VSC is unavailable, a display panel can be used. IAS detectors can only be configured via their user interface. Airflow and smoke alarm thresholds should ideally be determined using ASPIRE pipe network configuration software. Upon first power-up, Xtralis VSC registers all ICAM detectors as unconfigured, with other products appearing under ancillary devices. Detailed explanations for Xtralis VSC software and detector setup via display panel are available in the online help and relevant product guides.

ICAM systems can be tested in various ways, depending on customer environment and local codes/standards. Local codes may override ICAM suggestions. Performance testing is done during commissioning and may be required during service, but pipe integrity testing is highly recommended annually. Note: Some tests generate significant smoke, requiring precautions.
This test proves pipe network integrity and measures response time. The type of test depends on the site and application:
In high-roof areas, warmer air near the roof can cause smoke stratification, preventing smoke from reaching roof-mounted sample points. To counteract this, a larger distance between the roof and the sampling point may be needed as roof height increases. Standard 25 mm (1 in.) standoffs are suitable for heights up to 3 m (9 ft). For higher roofs, distances increase: 100mm for 4m, 200mm for 5m, 300mm for 6m, 400mm for 7m, 500mm for 8m, 600mm for 9m. A 5.8 kW gas burner or electric heater can be used to add heat to the smoke to ensure it reaches the roof.
This method is for standard sensitivity fire detection systems in typical customer sites. It requires a smoke source, stopwatch, and fire extinguisher. Detectors with display modules show increased smoke levels.
Suitable for high and enhanced sensitivity environments. Requires smoke pellets, a tray, and a timer. A radiated heater may be needed for high-roof areas to fix stratification.
For more information, refer to BFPSA or FIA CoP standards.
Suitable for standard sensitivity fire detection systems. Involves lighting a flexible polyurethane foam mat. This test is for open areas like warehouses and atriums. Warning: Burning polyurethane foam generates toxic gases. Use appropriate protective equipment.
Legend: A = 500mm (20 in), B = Kitchen foil in tray, C = 20mm (0.874 in).
This test simulates early fire stages for high sensitivity fire detection systems, suitable for underfloor spaces or ceiling voids. It involves overloading a 1-meter length of PVC-coated wire (10/0.1 mm strands, 0.3 mm radial thickness, 0.078 mm² conductor area) using a transformer. Xtralis offers a VTT-10000 test kit. Warning: Burning PVC coating is harmful. Do not hold the wire. Remotely turn on the transformer and use appropriate protective equipment.
Record the following on the commissioning form:
Acceptable response times are determined by site requirements, local codes, and standards. If test response times don't meet standards, the commissioning form should be signed as "NOT ACCEPTABLE," with recommendations for further work recorded.
Outputs for IFT detectors can be tested using a diagnostic test accessed via the TEST OUTPUTS menu function. Refer to the IFT Product Guide for details.
Test results must be recorded on ICAM commissioning forms. Once completed and signed, forms and attachments should be forwarded to all relevant parties mentioned in Chapter 6. Copies of commissioning forms are available in the document library at www.xtralis.com (Xtralis document number 16022).
Both the engineer and customer must be satisfied that all commissioning aspects meet required standards and the system is ready for day-to-day operation. To hand over the system:
