Aiphone Ix-ssa-ra - IP Audio Emergency Station SIP Compatible ADA Compliant 1 Call Button

Aiphone IX-SSA-RA IP Audio Emergency Station

The Aiphone IX-SSA-RA is a flush-mount IP audio emergency station purpose-built for ADA-compliant safety communication in public facilities, campuses, parking structures, and transportation hubs. This model operates as a SIP endpoint (IPv4/IPv6 compatible) with PoE or 24V DC power options, making it suitable for both new builds and retrofit deployments where hardwired infrastructure is already in place.

Overview

The IX-SSA-RA delivers one-way audio push-to-talk functionality with support for up to 20 concurrent call stations on a single system. Unlike video-centric solutions, this audio-only approach keeps bandwidth overhead minimal and eliminates video storage concerns—critical in large-scale emergency notification networks. The unit draws only 3.36W via standard PoE (802.3af class 0) or optional 24V DC, so power delivery is straightforward on existing switches without special PoE+ budgeting. The housing achieves IP65 (dust and water jet protection) and IK08 impact rating, meaningful spec language for outdoor wall-mount or harsh-environment installations where the unit faces weather, physical contact, or vandalism risk.

Key Features

• SIP Protocol & Standards Compliance: Native SIP, IPv4/IPv6, TCP/UDP, HTTP/HTTPS, RTSP/RTP/RTCP support means direct integration with enterprise VoIP infrastructure—no proprietary gateway required. Your existing call server (Asterisk, FreePBX, Cisco, Avaya) can route emergency calls without translation layers.
• ADA Accessibility by Design: Single large call button with tactile feedback and integrated LED status indicator meets Americans with Disabilities Act requirements for audible and visual feedback. Button is positioned at standard mounting height (11-11⁄16" tall unit) to ensure reach-range compliance for wheelchair users.
• Dual Audio Codec Support (G.711 & G.722): G.711 (μ-law and A-law) is the industry default for North American and international PSTN compatibility; G.722 offers higher bandwidth (7 kHz audio) if your call server supports it. This flexibility avoids codec negotiation bottlenecks in hybrid legacy/modern networks.
• Volume Range 73–96 dB: Adjustable output level ensures audibility in noisy environments (outdoor parking, loading docks, industrial floors) without overwhelming indoor corridors. 96 dB is loud enough for attention-grabbing alerts but controllable to avoid discomfort in quiet zones.
• PoE Pass-Through with Type 2 Support: Two RJ45 in/out network ports with integrated PoE passthrough (802.3at Type 2 PoE+) allow daisy-chaining of secondary devices or PoE-powered speakers on the same circuit. This is a real timesaver in facilities where you want to avoid separate power drops for each endpoint.
• Two Relay Contact Outputs: Built-in dry-contact relays enable integration with door strikes, sirens, beacon lights, or HVAC shutdowns—useful for coordinating emergency response beyond just audio notification. Contact output logic can be programmed via SIP server or local configuration.
• IEEE 802.1X Port Security: Network authentication prevents unauthorized devices from joining the emergency call system, a requirement in regulated environments (healthcare, government, education) where call-hijacking or spoofing poses a liability.
• Flush or Surface Mount Flexibility: Supplied with back box for flush installation into wall cavities; alternatively compatible with Aiphone stainless-steel surface boxes (SBX-IDVFRA) and modular emergency towers (WB-CA, WB-HA, WB-CE, WB-HE). This modularity reduces design constraints when exact wall depth or aesthetic preferences vary site to site.
• Operating Range -40° to 140°F (-40° to 60°C): Rated for outdoor, unheated, and high-temperature industrial environments. Real-world implication: no seasonal shutdown or thermal derating in cold-storage facilities, roof-mounted stations, or sun-exposed exterior walls.
• microSD Card Slot: Local recording capability (codecs and duration depend on card capacity) for audit trails and regulatory compliance. Useful for post-incident review or proof of emergency notification timing.

Integration & Compatibility

The IX-SSA-RA integrates into any SIP-capable VoIP platform. If you are deploying a networked security system alongside emergency audio, the station can coexist on the same managed network switch infrastructure without special VLAN carving or QoS overhead. Audio streams are real-time but low-bitrate (G.711 at roughly 64 kbps + overhead); even on shared 1 Gbps switches with dozens of devices, contention is negligible.

Port security via 802.1X and standard IPv4/IPv6 DHCP provisioning fit existing enterprise directory and certificate management. If your facility uses Cisco, Avaya, or open-source (Asterisk/FreePBX) call systems, SIP registration is immediate once credentials are supplied. The SMTP/SFTP protocols enable remote logging of call events to a syslog server or backup call archive.

Frequently Asked Questions

Q: Is the IX-SSA-RA suitable for outdoor/weather-exposed mounting?

A: Yes. The IP65 rating and -40° to 140°F operating range support direct outdoor installation. Pair it with the optional SBX-IDVFRA stainless-steel surface mount box for enhanced corrosion resistance in marine or chemical-spray environments.

Q: Can the IX-SSA-RA record emergency calls locally?

A: Yes. The microSD card slot allows local audio recording for compliance and audit trails. Recording duration depends on card capacity and audio codec; G.711 at 64 kbps on a 32 GB card will record approximately 45 hours of audio.

Q: What VoIP systems does the IX-SSA-RA work with?

A: Any SIP-compliant PBX or VoIP platform: Asterisk, FreePBX, Cisco Unified Communications, Avaya, Poly, or cloud-based services (8x8, RingCentral, Vonage) that support standard SIP registration and call routing. No proprietary gateway required.

Q: How much network bandwidth does a call use?

A: G.711 audio is approximately 64 kbps RTP payload plus protocol overhead (~80–100 kbps total per call). With 20 simultaneous calls, peak usage is roughly 2 Mbps—negligible on modern enterprise switches.

Q: Can the relay outputs trigger external devices?

A: Yes. The two dry-contact relay outputs can activate door strikes, sirens, strobes, or HVAC shutdowns. Relay logic is configurable via SIP server commands or local administration interface.

Q: Does the IX-SSA-RA comply with ADA requirements?

A: Yes. Single large call button with tactile feedback, integrated LED status indicator, and standard mounting height (11-11⁄16") meet ADA accessibility standards for audible and visual feedback in emergency communication systems.

Jerry Tildsen

I've specified the Aiphone IX-SSA-RA in higher-ed campuses, healthcare facilities, and parking structures where emergency audio notification is non-negotiable. The SIP protocol is a game-changer here—no proprietary hardware or licensing lock-in. Once it's registered to your existing PBX, it behaves like any other VoIP endpoint. The 3.36W PoE draw is tiny; even on a modest 48-port PoE switch, you can deploy 20–30 of these without exhausting budget. The ADA compliance piece is built in, not an afterthought—the call button, LED feedback, and mounting dimensions all meet code right out of the box.

Technical Highlights:

• SIP + Open Protocols (IPv4/IPv6, RTSP/RTP/RTCP): Zero vendor lock-in. Integrates with Asterisk, Cisco, Avaya, or any standards-based PBX. If you migrate call systems in five years, the IX-SSA-RA comes with you—no forklift replacement.
• 3.36W PoE (802.3af class 0) + PoE passthrough: Tiny power footprint frees up budget on your switch. The daisy-chain capability (RJ45 in/out with Type 2 PoE+ passthrough) means you can run secondary PoE speakers on the same circuit drop. Real cost saving in retrofit scenarios.
• IP65 + IK08 + -40° to 140°F Operating Range: Outdoor-rated, full-season capability. No thermal derating in summer heat or winter cold. IK08 impact rating means it shrugs off casual vandalism or accidental strikes—not true of every consumer-grade audio panel.
• Two Relay Outputs + microSD Recording: Beyond audio notification, the relays trigger door locks, sirens, or strobes. microSD recording is compliance gold—time-stamped proof of who called and when, invaluable in post-incident review or regulatory audit.

Deployment Considerations:

• SIP registration is only as secure as your network authentication. Enable 802.1X port security and require strong PBX credentials—unsecured SIP endpoints are an easy attack vector. The IX-SSA-RA supports 802.1X, but it's on you to enforce it at the switch.
• Volume range (73–96 dB) is great for outdoor or noisy zones, but if you mount it in a quiet hallway, 96 dB will startle people. Plan speaker placement and test volume levels in situ before commissioning.
• PoE passthrough works with Type 2 (PoE+, 30W max), not PoE++ (Class 4+). If you plan to daisy-chain a high-power device (e.g., a PTZ or powered siren), check wattage limits.

The IX-SSA-RA shines in campus safety, healthcare emergency codes, and parking structure panic call systems—anywhere you need open-standard emergency audio without the complexity of a closed proprietary ecosystem. Its small footprint and PoE efficiency make it practical to deploy in numbers across large facilities.
