Electronics Board
The ACX-220 electronics board features several key components:
- 1. APS connector: For connecting a SATEL power supply unit (e.g., APS-412).
- 2. LED indicator: Flashes when communication with a controller is active.
- 3. Relay Output LEDs: Indicate the status of the relay outputs. OFF signifies an inactive output, while ON signifies an active output.
- 4. Tamper switch: Detects cover removal.
- 5. Antenna: For radio communication.
Terminals:
- COM: Common ground.
- +12V: Power input or +12 VDC power output when the module is powered via the APS connector.
- TMP: Tamper output (normally closed contact).
- Z1...Z4: Zone inputs for connecting detectors.
- C1...C4: Common contact for relay outputs.
- NC1...NC4: Normally closed contact for relay outputs.
- NO1...NO4: Normally open contact for relay outputs.
Installation
Disconnect power before making any electrical connections.
The ACX-220 expander should be installed indoors in spaces with normal air humidity. Thick walls and metal partitions can reduce radio signal range. Mounting the expander high above the floor is recommended to improve radio communication range and prevent accidental obstruction. Avoid installing the device near electrical systems, as this may adversely affect radio signal range.
The expansion module can be powered from a SATEL APS-412 power supply unit connected to the APS connector, or alternatively from the +12V and COM terminals. In the latter case, the control panel, expander with its own power supply, or a separate power supply can be used.
[info] If a power supply unit is connected to the APS connector, the expander will report the following power supply unit troubles: loss of 230 VAC mains, low battery, or power supply overload.
- Loosen the screws securing the enclosure cover and remove it.
- Connect a temporary 12 VDC power supply to the expander.
- Add the expander to the wireless system. Refer to the ABAX 2 / ABAX controller manual or the INTEGRA 128-WRL control panel installer manual. The serial number required for registration is on the electronics board. Note: In INTEGRA / VERSA alarm systems, the expander is identified as ACX-201. Simultaneous operation of the expander by ABAX 2 and ABAX controllers / INTEGRA 128-WRL control panels is not possible.
- Place the expander in its intended installation location.
- Check the signal strength received by the ABAX 2 / ABAX controller or INTEGRA 128-WRL control panel. If the signal level is below 40%, select a different installation spot. Minor adjustments of ten to twenty centimeters may suffice. The ARF-200 tester can be used to check radio signal strength at the intended location without installing the expander.
- Disconnect the temporary 12 VDC power supply.
- Make a hole in the enclosure base for the wires.
- Run the wires (power cables, detector connection cables, etc.) through the hole.
- Secure the enclosure base to the wall using appropriate wall plugs (screw anchors) and screws, selected based on the mounting surface type (e.g., concrete, brick, plaster).
- Connect detectors to the expander zones. Use a 2.2 kΩ resistor for EOL configuration or two 1.1 kΩ resistors for 2EOL configuration.
- If the tamper switch is to be supervised, connect its output terminals to an expander zone. This zone can be configured as 2EOL, allowing the tamper output and detector to be connected in series.
- Connect devices to the expander outputs.
[info] Given the nature of radio communication, it is not recommended to use the expander in applications requiring rapid output status switching.
- Depending on the chosen powering method, connect the power supply unit to the APS connector or connect the power leads to the +12V and COM terminals. Use flexible conductors with a cross-section of 0.5-0.75 mm² or rigid conductors with a cross-section of 1-2.5 mm².
- Never connect power supply to the APS connector and terminals simultaneously.
- Replace the cover and secure it with the screw.
- Power up the expander.
- Configure the expander settings by referring to the ABAX 2 / ABAX controller manual or the programming manual for INTEGRA, VERSA, and PERFECTA 64 M series control panels.
[info] To comply with EN50131-3 standard requirements, set the alarm zone sensitivity to 400 ms.
