The Fanvil PA2S is an industrial-grade SIP paging gateway designed for enterprise audio-video intercom and public address systems. Using standard IP/RTP/RTSP protocols, it enables organizations to deploy scalable broadcast, intercom, and emergency notification infrastructure without proprietary hardware requirements.

Built for integration flexibility, the PA2S connects external devices including microphones, cameras, passive speakers, and security sensors through multiple I/O interfaces. Its compact 113mm x 83mm x 28mm form factor supports diverse deployment scenarios from wall-mounted emergency stations to rack-integrated control panels.

Best For

The PA2S serves organizations requiring integrated voice and video communication with broadcasting capabilities across distributed facilities.

- Educational Campuses: Schedule automated announcements, enable emergency lockdown notifications, and provide two-way intercom at building entrances with synchronized video verification

- Healthcare Facilities: Deploy nurse call stations with video verification, broadcast paging to specific zones, and integrate PIR sensors for patient monitoring alerts

- Industrial Parks: Create emergency call points at remote locations with weatherproof enclosures, trigger automated alarms via relay outputs, and centralize incident management

- Transportation Hubs: Distribute live announcements to passenger areas, connect door access controls with visual verification, and activate alarm signals during security events

- Corporate Facilities: Implement reception area intercoms with video, broadcast background music or alerts to office zones, and integrate with existing IP-PBX systems

Key Features

- Dual SIP Registration: Supports two concurrent SIP lines with independent call handling and SIP hotspot mode for group ringing across multiple PA2S units

- Video Intercom Integration: Connects IP cameras via RTSP for audio-video intercom sessions with NVR recording capability through standard RJ45 interface

- Flexible Power Amplifier: Integrated Class D amplifier scales from 5W (PoE) to 30W (24V external) based on 4Ω/8Ω speaker load and power input selection

- Multicast Broadcasting: Receives up to 10 multicast addresses without SIP signaling for simultaneous zone paging and scheduled announcements

- Emergency Call Interface: Dedicated button and LED port for one-touch emergency calls with customizable alert destinations and visual status indication

- Security I/O Ports: Switch input/output terminals connect PIR sensors, alarm lights, door strikes, and relay-controlled devices for automated response actions

- Audio Recording Output: 3.5mm line-out port enables call recording or connection to external powered speakers and audio distribution systems

- Wide Codec Support: Narrowband (G.711, G.729, G.723, G.726) and wideband (G.722, Opus) codecs with full-duplex acoustic echo cancellation

What deployment scenarios is the Fanvil PA2S best suited for?
The PA2S works for environments needing combined paging, intercom, and emergency notification with video verification. It handles campus-wide announcements, building entry intercoms with camera feeds, remote emergency call points with alarm triggers, and zone-based broadcasting in facilities up to medium scale. The dual SIP lines support both regular intercom traffic and dedicated emergency channels simultaneously.
How does the PA2S compare to traditional analog paging systems or basic SIP adapters?
Traditional analog paging requires separate devices for video, emergency buttons, and amplification. Basic SIP adapters lack power amplifiers and security I/O. The PA2S integrates all functions in one unit with dual SIP lines, built-in 30W amplifier, RTSP video support, and alarm relay outputs. This reduces equipment count and wiring complexity compared to multi-device analog installations.
What factors determine if the PA2S provides sufficient value compared to higher-end intercom controllers?
The PA2S delivers strong value when you need video intercom and amplified paging but not advanced features like touchscreen displays or door controller licensing. It costs less than full intercom stations while handling most paging gateway functions. Consider higher-end units only if you require local user interfaces, complex access control logic, or centralized multi-site orchestration beyond basic cloud management.
Which IP-PBX systems and camera brands work with the PA2S?
The PA2S registers with any SIP-compliant IP-PBX including Asterisk, 3CX, Broadsoft, and FreePBX. It connects to IP cameras supporting RTSP streaming over standard RJ45 Ethernet. The device uses open protocols (SIP, RTP, RTSP) rather than proprietary signaling, ensuring broad compatibility with enterprise VoIP and IP video systems already deployed.
What power supply options does the PA2S support and how does power source affect amplifier output?
The PA2S accepts PoE (IEEE 802.3af Class 3) or 12-24V DC external adapters. With PoE and 4Ω speakers, output is 10W. External 12V delivers 10W, 18V delivers 20W, and 24V delivers 30W at 4Ω. Higher speaker impedance (8Ω) reduces output proportionally. The device auto-switches to external power if PoE fails, ensuring continuous operation.
How many concurrent calls or broadcast sessions can the PA2S handle?
The PA2S supports two concurrent SIP registrations and can handle calls on both lines simultaneously. It receives up to 10 multicast paging addresses without SIP signaling for zone broadcasts. In SIP hotspot mode, one PA2S acts as server while others become clients, allowing group ringing and shared line appearances across multiple units without consuming additional SIP accounts.
What microphone specifications are required for the MIC/Line-in port?
The terminal-block MIC input requires electret condenser microphones with -38dB sensitivity, 2.2kΩ impedance, and 2.54Vpp bias voltage. The port defaults to microphone mode but can be configured via web interface as line-level input for connecting audio sources like FM tuners or mobile devices. Line-out mode supports external powered speakers or recording devices through 3.5mm jack.
Can the emergency call button trigger automated actions beyond placing a SIP call?
The button port initiates SIP calls to preconfigured destinations and can activate LED indicators via dedicated 5V/5mA output. When combined with switch I/O ports, the PA2S triggers relay-controlled devices like alarm lights, door strikes, or sirens. Web configuration maps button presses to multiple simultaneous actions including SIP calls, multicast alerts, and relay activations for coordinated emergency response.
