TOA IP-A1SC15 IP Horn Speaker, PoE/PoE+, 15 W, IP66

Introduction: TOA IP-A1SC15 at a glance

The TOA IP-A1SC15 IP horn speaker is a purpose-built outdoor paging loudspeaker designed for demanding perimeter and industrial applications. With a built-in Class-D amplifier, PoE/PoE+ power support, SIP/ONVIF and multicast network audio compatibility, and on-device playback of pre-recorded messages, the IP-A1SC15 combines rugged weatherproof construction with modern IP audio features. It delivers high sound-pressure levels (up to 124 dB SPL at 1 m when powered by PoE+) and flexible network control, making it a strong choice for sites that require intelligible, reliable outdoor paging.

Key features

• High output:Up to 124 dB SPL (1 m) when powered by PoE+ (15 W).
• PoE/PoE+ support:Single-cable data and power via IEEE 802.3af/at simplifies installation.
• Network-first:SIP/VoIP, ONVIF audio backchannel, RTP/RTSP, multicast and HTTP API control for integration with VMS and SIP systems.
• On-board playback:Stores up to 20 WAV/MP3 files (~80 MB) for scheduled or triggered announcements.
• Ruggedized enclosure:IP66-rated housing and wide operating temperature range (−30 °C to +55 °C) for outdoor environments.

Detailed specifications and benefits

• Amplifier output:15 W with PoE+ (IEEE802.3at Class 4); 8 W with PoE (IEEE802.3af). This internal Class-D amp offers efficient power use and solid output for typical outdoor paging scenarios.
• Maximum SPL:124 dB at 1 m (PoE+); 121 dB at 1 m (PoE). That level of acoustic output is suited to long-range paging, perimeter alarms and noisy construction environments.
• Sensitivity & response:112 dB (1 W, 1 m) sensitivity and a usable frequency range from about 280 Hz to 12.5 kHz – tuned for voice clarity rather than deep bass, which is typical and appropriate for horn-style paging speakers.
• Supported codecs:Opus, PCMU/PCMA (G.711), and G.722 (mode-dependent) allow compatibility with a range of SIP endpoints and VMS implementations while helping maintain speech intelligibility over networks.

• Network interface:100BASE-TX RJ-45 with Auto MDI/MDI-X.
• Protocols:SIP (RFC3261) for VoIP paging, ONVIF for audio backchannel with many video management systems, RTP/RTSP for streaming, HTTP API for remote control, plus IGMPv3 and NTP for multicast and time synchronisation.
• Remote control:Can be controlled via SIP calls, multicast streams or HTTP API commands; suitable for centralized paging servers or local VMS-triggered announcements.
• Control I/O:Two no-voltage contact inputs and an open-collector output offer simple local control, trigger integration and fault monitoring.

• Up to 20 pre-recorded files (~80 MB total) in WAV or MP3 format can be stored on the device and played on schedule, by trigger or on repeat. This is useful for routine announcements, warnings, and automated messages without reliance on a network stream.

• Ingress protection:IP66-rated enclosure and components (aluminium horn flare, ABS reflector, PC rear cover) that resist dust and heavy spray for reliable outdoor service.
• Operating conditions:−30 °C to +55 °C and up to 90% relative humidity (non-condensing), allowing deployment in a wide range of climates.
• Mechanical:Compact footprint (222 × 211 × 276 mm) and lightweight (1.4 kg) with stainless-steel mounting bracket and fasteners for secure mounting on walls or poles.
• Power considerations:Use PoE+ switches or midspan injectors where full 15 W output is required; PoE (802.3af) will deliver reduced amplifier output (8 W) but still supports many paging needs.

Benefits in practical terms

• Simplified installation:PoE/PoE+ eliminates separate power runs, reducing cabling and installation cost for distributed outdoor nodes.
• Flexible integration:SIP and ONVIF support mean the speaker can be integrated into telephony-based PA systems or VMS platforms without proprietary gateways.
• Local resilience:On-board audio playback ensures critical messages can still be delivered if network streaming is interrupted.
• High intelligibility outdoors:The horn design and focused frequency response prioritise speech clarity at distance, a key requirement for perimeter and safety announcements.

Use cases and real-world scenarios

The TOA IP-A1SC15 fits many outdoor and industrial paging needs. Typical deployments include:

• Perimeter security:For large sites or fenced perimeters, the horn speaker delivers clear deterring announcements and alarm tones that can be centrally triggered from a security console or VMS.
• Construction and industrial sites:Harsh environments and high ambient noise make a weatherproof horn with high SPL and focused speech response essential for safety messages, shift calls and evacuation alerts.
• Parking lots and transport hubs:Staff paging, public safety announcements and automated messaging (lot closing, suspicious activity alerts) can be handled via SIP or timed on-board playback.
• Integration with video systems:ONVIF audio backchannel and HTTP control allow VMS software to trigger live or pre-recorded voice warnings tied to camera analytics (motion, intrusion, loitering).
• Distributed emergency voice alarm:When used with compatible controllers and SIP systems, the device can be part of an emergency voice alarm network for outdoor areas where intelligible voice evacuation is needed.

How it compares to similar products

When evaluating the TOA IP-A1SC15 against other outdoor paging options, consider these comparison points rather than single-number specs:

• PoE vs. mains-powered horns:PoE/PoE+ simplifies cabling and centralises power management, whereas mains-powered horns may deliver higher continuous power but require separate electrical runs and protection.
• On-board storage:Not all IP horn speakers include local file playback; the IP-A1SC15's ability to store up to 20 messages is an advantage where network reliability is variable or where scheduled announcements reduce operator load.
• Protocol support:SIP and ONVIF compatibility gives the TOA unit broad interoperability with telephony and video systems. Some competitive units may support proprietary protocols or only multicast streaming, limiting flexibility.
• Ingress rating and build:IP66 is common in this segment; the TOA's alloy horn and stainless hardware provide a good balance of durability and weight for mounting on posts or walls.
• Acoustic output:124 dB SPL is at the higher end for PoE-powered horns. If you need extreme long-range coverage in very noisy sites, higher-powered mains horns exist, but they increase installation complexity.

Customer feedback and testimonials

Installation, safety and compliance notes

• Install in accordance with local electrical and safety regulations. Use PoE/PoE+ switches or certified midspan injectors capable of delivering the necessary power budget if maximum output is required.
• Secure mounting with the supplied stainless-steel bracket is important for long-term stability in windy or exposed sites.
• Manufacturer certification details such as CE/UKCA should be confirmed from the official TOA datasheet where up-to-date regulatory declarations are provided.
