Point Detectors
Ensure that the selected detectors have sufficient sensitivity for the application. See Section 5: Pipe
Installation for further details of how dilution affects detector sensitivity.
If the installation is to be done in accordance with AS 1603.8 under the ActivFire scheme, then the detector
must have been tested for use in the system. Please refer to the list of approved detectors in Section 9: AS
1603.8 Listed Detectors.
4.1
Baffles
Due to the large variation in the sizes and shapes of point detectors it is necessary to fit baffles to the IAS-1
system to ensure that the sampled air flow is directed toward the detector. Each baffle is shaped to match a
particular model/range of detectors and simply clips into position in the slots provided in the transparent lid.
Please contact your local Xtralis ICAM distributor for ordering information.
4.2
Detector Installation
One or two conventional or analog addressable point detectors are attached to the mounting board using the
provided screws.
Addressable loop or conventional circuit wiring can be connected to the point(s) with either of two methods:
the wiring can be connected to the LOOP IN and LOOP OUT terminals on the main circuit board (refer
l
to Figure 3-1). Additionally, the terminals on the point(s) must be connected to the detector terminals
located in the center of the point mounts on the mounting board. This is the preferred method. Refer to
Section 4.3.3: Configuration with Units Connected in Series for further information.
the wiring can be connected directly to terminals on the point. It should be routed via the cutouts in the
l
mounting board. Refer to Section 4.3.1: Configuration with two Addressable Detectors for further
information.
When one point detector is installed, the detector should be placed in the Channel 1 position.
Note: The LOOP IN and LOOP OUT terminals are linked and the local detector terminals on the
display/mounting board are connected to these terminals via the ribbon cable.
4.3
Wiring Examples
The following examples show typical installations for conventional and analog addressable detectors. Please
ensure that all wiring complies with manufacturer's instructions and local and national fire detection code
requirements.
