*Specifications are measured under laboratory conditions. Actual performance may vary depending on operating
environment and application-specific factors.
*Star topology is supported only in compatible mode or via a bus hub. Connecting multiple branches to a single bus port may
significantly reduce bus range.
*Quiescent current is specified in Wi-Fi standby mode, with Ethernet and all communicators disconnected.
*Battery standby duration applies when all functions are operational and the load connected to the AUX-/AUX+ terminals
does not exceed 336 mA.
*ARC signalling complies with SIA IP Reporting (UDP/TCP-2013) as per ANSI/SIA DC-09-2013. The control panel supports
ADM-CID and SIA-DCS protocols defined in SIA DC-07-2001.04. When transmission messages are AES-encrypted, a “*” is
prefixed to the protocol name (e.g., *ADM-CID, *SIA-DCS). Supported encryption levels include AES-128, AES-192, and
AES-256.

Is the DS-PA502-128 compatible with 5GHz Wi-Fi networks?
No, this control panel supports 802.11b/g/n protocols specifically on the 2.4GHz frequency band. Ensure your router is configured for 2.4GHz to maintain a stable connection for your security system.
Does the system support video verification with my existing IP cameras?
Yes, this panel supports video verification for up to 16 network camera channels (720p) or 8 channels (1080p). It captures a 7-second clip upon an alarm event, which can be sent to your mobile device for immediate verification.
What should I do if I encounter configuration issues during installation?
For detailed installation guidance or specific troubleshooting beyond the provided manual, please contact our technical support team directly at [email protected] for professional assistance.
Does this alarm system come with the necessary regional firmware for use in the Baltics?
Yes, this is the official EU version compatible with standard Hikvision management software and the Hik-Connect mobile application. It is fully compliant with EN50131 Grade 2 standards for high-security environments in Europe.
How does the warranty work if I purchase the control panel from Apsardze24.lv?
We provide a full 2-Year Warranty for all private and business clients. Because our service center is located in Riga, we offer significantly faster turnaround times for repairs or replacements compared to international marketplace vendors.
What power supply or backup battery is included with the HIKVISION DS-PA502-128?
The control panel does not include a battery by default; you will need to purchase a 12VDC lead-acid battery (up to 7Ah) separately to ensure up to 12 hours of standby time. The unit accepts a 100-240VAC mains input, but the battery must be sourced independently.
How many wired devices can I connect to the HIKVISION AX Hybrid PRO G2?
The system supports up to 128 zones and 128 outputs, with 64 bus devices allowed per bus. It utilizes two RS-485 bus ports that support various topologies like Daisy Chain, Cascade, Star, or Ring.
