9 AS 1603.8 Listed Detectors
The following detectors have been independently tested and certified for use in the IAS-1 unit. The table
shows the limits which should not be exceeded if the installation is to conform to this requirement. All figures
are based on the standard configurations shown in Section 9. Pipe lengths are 60 m for a single pipe, and 35 m
per pipe for a tee / two pipe configuration unless otherwise stated.
All point detectors are analog addressable with programmable smoke sensitivity. Under the ActivFire listing,
point detectors should be set to and operated at the most sensitive setting. Please refer to the appropriate fire
panel user manual for instructions.

Notes:
1. Holes in the endcap are considered to be sampling holes.
2. The IAS decal on the front of the detector must be removed when this point is installed.
9.1 Sampling Pipe Network Design
The IAS-1 supports a number of pre-engineered pipe network designs.These designs incorporate suction
pressure and transport time considerations. For setup details, refer to the Xtralis ICAM Pipe Network Design
Guide (Document 14966).
CAUTION: The performance of this system is dependent upon the pipe network. Any extensions or
modifications to the designed installation may cause improper operation. The operational
effects of such changes shall be verified. Any changes must be carried out in accordance
with the pre-engineered pipe networks defined in this document.
The pre-engineered designs assume the following constraints:
1. All sampling points are open holes.
2. For branched designs, the pipes should be balanced, be of equal length and have an equal number of
sampling holes along each branch.
The pre-engineered pipe network designs provide:
l
Transport Times: <90 Seconds
l
Suction Pressure: Greater than or equal to 115 Pa
l
Sampling Point Sensitivity: <=10%
The information below shows the parameters for pre-engineered designs.
