The IP-A1PG is a compact, Power over Ethernet (PoE) powered gateway unit designed to bridge disparate communication and security networks into a unified IP-based public address system. Operating as a critical integration hub within TOA’s IP Audio ecosystem, it converts legacy analog audio signals, Session Initiation Protocol (SIP) telephony voice streams, and Video Management System (VMS) ONVIF backchannel audio directly into stable multicast network audio streams. This enables flexible group paging, automated event broadcasting, and precise scheduling across vast enterprise networks.

SKYRS guarantees regional stock allocation, hardware provisioning kits, and specialized ecosystem matching for all installation types across industrial, commercial, and safe-city grids throughout Pakistan (including major technical fulfillment hubs in Karachi, Lahore, Islamabad, Faisalabad, and Peshawar).
IP-A1PG-ST (Standard Surface Kit): The core gateway unit delivered with integrated rubber isolation pads and internal chassis screws. Perfectly suited for quick, decentralized deployments on utility desks, network backboards, or structural shelves.
IP-A1PG-RM (Rackmount Integration Pack): Packaged with customized rack ears designed to horizontally gang multiple IP-A1 series gateway devices within a standard 1U/2U server rack layout alongside primary IT networking gear.
IP-A1PG-DIN (DIN-Rail Mounting Variant): Shipped with heavy-duty clip adapters tailored for snapping the gateway securely into standard industrial DIN-rail paths located inside centralized electrical control boxes or industrial automation enclosures.
To preserve system reliability and protect warranty frameworks across sensitive IT infrastructure, turn-key deployment, field assembly, and software logic mapping are handled exclusively by certified SKYRS engineering wings within Pakistan.
Chassis Attachment & Space Allocation: Structural placement of the gateway based on site requirements (DIN-rail clipping, server rack grouping, or wall cabinet anchoring).
Signal Interfacing & Ground Alignment: Terminating analog background music (BGM) playback sources or balanced localized microphones to the 6-pin input terminal block. Ensuring proper shield grounding to eliminate local RF interference.
Integrated Control Cabling: Hardwiring the 4 control inputs directly into external sensors, panic buttons, or access control relays. Interfacing the 24 V DC mute control loop to local fire alarm panels for immediate system attenuation during emergencies.
PoE Network Drop Verification: Interfacing the single RJ45 port into high-performance PoE network switches using certified Cat6 infrastructure cabling, evaluating packet delivery rates, and validating power consumption levels.
SIP Telephony Integration: Registering the gateway as a dedicated SIP endpoint within local IP-PBX phone servers, enabling users to broadcast directly to public address zones simply by dialing an internal extension number.
VMS and ONVIF Bridge Mapping: Establishing security network handshakes to intercept ONVIF backchannel voice outputs from central Video Management Software platforms, instantly transmitting security audio to multi-zone IP horns.
Multicast Routing and Zone Allocation: Configuring the internal address translation table to route incoming unicast audio streams into up to 20 synchronized multicast addresses over the network.
Web-GUI Scheduler Setup: Configuring the built-in calendar schedule matrix (supporting up to 2,000 automated items) to handle shift changes, daily operational chimes, and automatic announcements directly from the device without external scheduling software.
HTTP/HTTPS API Macro Programming: Writing and testing outbound HTTP command sets. When a physical control input is triggered, the gateway executes a macro that can simultaneously change device priorities, activate remote relays, or force downstream IP speakers to unmute and broadcast warnings.
