TOA Electronics Enclosure for SIP Module - SP-11NB-AM

Overview

DEAL: On Sale — The TOA SP-11NB-AM is a compact aluminum chassis enclosure for the SP-11N SIP VoIP phone paging module, enabling integration of the SP-11N into TOA 900 Series and 9000M2 Series amplifier/mixer frames for telephone-initiated paging in commercial public address systems.

Description

The SP-11NB-AM encloses the SP-11N circuit board in a standalone aluminum-panel chassis with front-panel hairline finish for rack-compatible mounting. It provides a 6-pin removable terminal block for 5 open-collector relay output channels (max 27 V DC / 50 mA per channel) to trigger zone activation or auxiliary devices. Network connectivity is via RJ-45 at 10/100BASE-TX auto-negotiation, supporting SIP (RFC3261), RTP, TCP/UDP, DHCP, BOOTP, SNMP, ICMP, and HTTP protocols. Audio encoding is G.711 μ-law/A-law. The unit is powered by the included AC-1215P AC adapter (or equivalent) and operates from 0°C to +40°C. The compact 35 × 78 × 91.4 mm footprint and 86 g weight allow easy mounting within AV racks or enclosures.

Key Features

• SIP VoIP paging integration — Enables telephone-initiated paging from any SIP-compatible PBX or VoIP system into TOA 900/9000M2 PA systems.
• 5 relay control outputs — Open-collector relay outputs (27 V DC / 50 mA max) for zone activation, tone triggering, or auxiliary device control.
• Standard IP protocols — Supports SIP (RFC3261), RTP, DHCP, SNMP, and HTTP for easy integration with enterprise IP networks.
• G.711 audio encoding — μ-law and A-law G.711 audio compatibility for standard telephony audio quality over IP.
• Compact aluminum enclosure — Hairline aluminum panel finish, 86 g, 35 × 78 × 91.4 mm for flexible mounting within racks or custom enclosures.

Typical Applications

The SP-11NB-AM is used in commercial and institutional environments where telephone-initiated paging is required: hospitals and healthcare facilities enabling nurse station or phone-triggered overhead paging without dedicated paging consoles; corporate campuses integrating IP PBX systems with TOA 900/9000M2 paging amplifiers for all-call or zone announcements; schools and universities requiring SIP-based paging from administration phones; and retail or industrial facilities adding automated or operator-dialed paging to existing TOA PA infrastructure.

Technical Specifications

FAQ

What is the relationship between the SP-11NB and the SP-11N?

The SP-11N is the SIP paging module circuit board; the SP-11NB-AM is its aluminum chassis enclosure. The SP-11NB-AM is purchased when you need the SP-11N to function as a standalone unit rather than as a plug-in module within a 900 Series frame.

Which TOA amplifier frames is the SP-11N compatible with?

The SP-11N is designed for use with TOA 900 Series and 9000M2 Series modular amplifier/mixer frames. When used standalone, the SP-11NB-AM enclosure provides the housing.

What PBX or phone system is needed?

Any SIP-compatible PBX or IP phone system supporting RFC3261 SIP, RTP, and G.711 audio can initiate paging through the SP-11N.

How many paging zones can the SP-11N control?

The SP-11NB-AM provides 5 open-collector relay outputs for zone switching or auxiliary triggering, enabling up to 5 independently controllable zones or functions.

Does the SP-11NB-AM include the SP-11N module?

The SP-11NB-AM is sold as the enclosure; verify with your distributor whether the SP-11N module is included or sold separately depending on the SKU configuration.
