ABAX
SYSTEM
The ACX-200 expander takes up 4 positions on the list of devices supported by the
controller. Up to 12 ACX-200 expanders can work together with the ACU-100 controller. The
expander sends to the controller information on the status of zones and receives commands
to change the status of relay outputs. The transmission of zone status information as well as
the output control are performed in real time mode. Only the information on expander zone
settings is sent during the response period. When polling, the controller will send information
to the expander, regarding configuration of one zone. This means that 4 response periods
are needed to send information on the settings of 4 zones. Consequently, even more than 2
minutes can elapse from the moment the new settings are programmed to the moment they
are actually saved in the expander (if the response period is 36 seconds). The settings of
expander zones are stored in non-volatile memory, hence the loss of power supply will not
mean any loss of preprogrammed settings.
Note:
If the communication with the ACU-100 controller is lost, all of the previously activated
outputs will enter the inactive state after 20 response periods.
In order to install the ACX-200 hardwired zone/output expander in the system, do as follows:
1. Open the housing.
2. Make cable inlets in the rear panel of the housing for power cables / cables connecting the
expander with hardwired devices.
3. Prepare a temporary source of 12V DC power supply and add the ACX-200 expander to
the wireless system (see: A
DDING NEW WIRELESS DEVICES
).
4. Select the place where the ACX-200 expander is to be installed and attach it there
temporarily. It is recommended that the expander be installed as high as possible. Thus
a better radio communication range can be obtained and the risk of the expander being
accidentally covered by personnel moving around the premises.
5. Check the level of signal received by the controller from the expander. Change the place
of installation, if necessary.
6. Having obtained the optimum signal level, install the expander permanently.
7. Connect the tamper contact to one of the expander zones. Program this zone as the
tamper zone. You can also connect the tamper contact in series with a 2EOL configured
device (detector), connected to one of the expander zones.
8. Connect wire devices to the expander zones/outputs.
Note:
The cables (for power supply, connection between the expander and hardwired
devices, etc.) should not be run in the immediate vicinity of the antenna, since it may
cause radio interference.
9. Configure the expander zones as required.
4.7.1 Configuration of ACX-200 expander zones/outputs for ACU-100 controller
operation with INTEGRA control panel
The ACX-200 expander occupies 4 zones and 4 outputs in the security alarm system.
Parameters of the ACX-200 zones and outputs are to be programmed in the same way as
those of the other hardwired zones and outputs of the control panel. However, it should be
borne in mind that the actual sensitivity of the ACX-200 zones may be different from that
programmed by means of the keypad or D
LOAD
X program. Within the range of 20ms to
140ms it will precisely correspond to the programmed value. Above 140ms, only some
sensitivity values are available in the expander (300ms, 500ms, 700ms, etc., in 200ms
increments). The values above 140ms, programmed by means of the LCD keypad or the
D
LOAD
X program, are rounded to the nearest value supported by the expander zones.
