If the controller is to be connected to the control panel to which an ABAX 2 / ABAX
controller is already connected, it is recommended that the address to be set in the
new controller be higher than that in the controller already connected to the control
panel.

Installation of the controller
Disconnect power before making any electrical connections.
Be careful during installation to avoid damage to the components located on the
controller electronics board.
4.1 Selecting a mounting location
The controller should be installed indoors, in spaces with normal air humidity. Prior to
installation you should plan the arrangement of all ABAX 2 wireless devices which are to be
operated by the controller. Select the installation place so that these devices are located
within the controller operating range. Remember that thick walls, metal partitions, etc. will
reduce the range of the radio signal. It is recommended that the controller be mounted high
above the floor. This will allow you to get a better range of radio communication and avoid
the risk of the controller being accidentally covered by people moving around the premises.
Installing the device in close vicinity of electrical systems is not recommended, since it can
adversely affect the range of radio signal.
Several ABAX 2 / ABAX wireless system controllers can work within each other's range. The
number of wireless devices working within each other's operating range depends on the
frequency of periodical communication. The higher the frequency of communication, the
lesser number of devices can work within each other's range.
4.2 Preparing the cabling
Run the cables to be used to connect the controller to the control panel or other devices to
the controller's installation location. For power cables, use flexible conductors with cross-
sectional area of 0.5-0.75 mm

. Do not lay the cables in immediate vicinity of the low-voltage
electrical network wires, especially those used for supplying the high-power equipment (such
as electric motors).
4.3 Installation of enclosure
The description below applies to the enclosure in which the ACU-280 controller is sold.
1. Open the controller enclosure (Fig. 4). The enclosure opening tool, shown in the
illustration, is included in the detector delivery set.
2. Place the enclosure base against the wall and mark location of the mounting holes. Set
the enclosure so that the cable entry opening is situated at the bottom of the enclosure or
at the base.
