Check that all electrical installations meet the requirements of local electrical codes and standards.
Data communication between detectors is done via an RS 485 network. The communication between devices
connected to the network is unidirectional. The polarity must be maintained throughout the network. It is
recommended that RS 485 (Belden 9841 - 120 ohm) twisted pair cables (or similar) be used. You must ensure
that the network is appropriately wired, please see the ICAM Communications Guide for further details.

You should now power up the system.
l
The system takes approximately 30 seconds to power up
l
If the system or any detector on the network fails to power up, re-check that all power wires are securely
connected to their respective terminals and the polarity is correctly maintained
During power up, different things will occur on different detectors at different times:
l
IFT detectors:
l
Sounder beeps
l
Aspirator starts
l
Display shows a rolling test message showing: IFT detector type, Software version and some
Optional text information
l
Fault indicators are activated for current faults
l
Current smoke background level (%obs/m) is displayed
l
Power LED turns on if there are no faults
l
IAS detectors
l
All LEDs turn on then off
l
Aspirator starts
l
Fault indicators are activated for current faults
l
High and low flow thresholds as well as current flow level are indicated on the bargraph
l
System OK LED turns on if there are no faults
l
ILS detectors:
l
All LEDs turn on then off about five times and the sounder beeps about five times
l
Aspirator starts
l
Fault indicators are activated for current faults
l
Smoke levels are indicated on the bargraph
l
System OK LED turns on if there are no faults
The detector(s) may show faults immediately after power up and this is normal. Reset the detector(s) to
unlatch the relays and fault LEDs. The fault LEDs on any display connected to the system will light up (this is
normal).
If any of the above does not happen, refer to the product guide for that detector and check that the detector
and RS485 network have been correctly installed.
3.3.2 Preliminary Systems Check
Conduct a preliminary systems check before you begin commissioning. The check can be conducted by
using Xtralis VSC software.
At power up or when changing site requirements a range of faults will be generated. This is normal. To silence
the faults you can accept the factory defaults, but you MUST remember that you still need to configure the
detector to suit the customer site. For further information see the product guide for the detector or the ICAM
Troubleshooting Guide.
Change the settings to suit site requirements:
l
Normalizing the air flow - Normalize the air flow using Xtralis VSC or the display panel (if applicable)
l
Create smoke at the farthest sampling hole from the Detector to confirm that the detector registers the
presence of smoke within the time anticipated by ASPIRE but also within the maximum time according to
local codes and standards. This test should be conducted for each pipe to ensure that there is no
blockage or leakage in any of the sampling pipes
For information on smoke tests please refer to Section 5.1.
