Indicates a potentially hazardous situation which, if mishandled, could result in moderate or minor personal injury, and/or property damage.

When Installing the Speaker

• Do not expose the speaker to rain or an environment where it may be splashed by water or other liquids, as doing so may result in fire or electric shock.
• Install the speaker only in a location that can structurally support the weight of the speaker and the mounting bracket. Doing otherwise may result in the speaker falling down and causing personal injury and/or property damage.
• Since the speaker is designed for indoor use, do not install it outdoors. If installed outdoors, the aging of parts causes the speaker to fall off, resulting in personal injury. Also, when it gets wet with rain, there is a danger of electric shock.
• Do not mount the unit in locations exposed to constant vibration. The mounting bracket can be damaged by excessive vibration, potentially causing the unit to fall, which could result in personal injury.

When the Speaker is in Use

• Should the following irregularity be found during use, immediately cut off the power supply from a PoE switching hub and contact your nearest TOA dealer. Make no further attempt to operate the speaker in this condition as this may cause fire or electric shock.
  • If you detect smoke or a strange smell coming from the speaker
  • If water or any metallic object gets into the speaker
  • If the speaker falls, or the speaker case breaks
  • If the LAN cable is damaged (exposure of the core, disconnection, etc.)
  • If the speaker suddenly stops producing sound

• To prevent a fire or electric shock, never open nor remove the speaker case as there are high voltage components inside the speaker. Refer all servicing to qualified service personnel.

• To prevent the electromagnetic wave from badly influencing medical equipment, make sure to switch off the speaker’s power when placing it in close proximity to the medical equipment.

When Installing the Speaker

• Attach the safety wire to the speaker. If not attached, the speaker could fall off, resulting in personal injury.
• Avoid installing the speaker in humid or dusty locations, in locations exposed to the direct sunlight, near the heaters, or in locations generating sooty smoke or steam as doing otherwise may result in fire or electric shock.
• Avoid touching the speaker’s sharp metal edge to prevent injury.

When the Speaker is in Use

• Do not operate the speaker for an extended period of time with the sound distorting. Doing so may cause the speaker to heat, resulting in a fire.
• Have the speaker checked periodically by the shop from where it was purchased. Failure to do so may result in corrosion or damage to the speaker or its mounting bracket that could cause the speaker to fall, possibly causing personal injury.

The IP-A1PC238 IP ceiling speaker is capable of delivering extremely high volume sound output. Therefore, close proximity to the speaker over time could present the danger of hearing impairment. Be sure to follow the instructions below when conducting performance tests:

• Turn down the sound volume before adjusting the volume.
• Do not position one’s ear close to the speaker.
• Point the speaker in a direction where no people are present.
• Avoid listening to high-volume output for prolonged periods of time.

2. SUMMARY AND FEATURES

The IP-A1PC238 IP ceiling speaker is equipped with a built-in power amplifier and sound source memory. It can be connected to and used over a local network.

• Power is supplied by way of PoE (IEEE 802.3af) switching hubs.
• The IP ceiling speaker is compatible with the following broadcasting modes:

Internal sound source broadcasting mode| Enables broadcast of up to 20 internal sound source files by means of control input or Remote API (HTTP).
---|---
VMS broadcasting mode| Enables backchannel audio broadcast from the VMS (Video management system) software using the common protocol for IP cameras.
SIP broadcasting mode| Enables SIP broadcasts from any voice communications device that utilizes the SIP protocol, such as SIP or IP telephone (IP-PBX) systems.
Multicast broadcasting mode| Allows up to 20 multicast ports to be set up, for 20 multicast audio stream paging groups.

• Orders of priority can be set among the various broadcasting modes, meaning higher priority broadcasts can interrupt and override lower priority broadcasts.
• Since the speaker is equipped with individual offset adjustable volumes for each broadcasting modes and patterns (internal sound source), actual broadcasting volume can be normalized or optimized.
• Broadcasts can be controlled using Remote API or control inputs from connected external equipment.
• Connected external equipment can be controlled by control outputs in synchronization with speaker broadcasts.

3. ABOUT SECURITY MEASURES

• Ensure that sufficient security measures are taken on the customer’s own responsibility.
• TOA Corporation takes no responsibility for damage or loss caused by security-related problems, such as illegal access.
• To help prevent illegal access to the speaker, be sure to change the user ID and password from those used for initial setup. For setting methods and other details, please refer to the separate setup manual which can be downloaded from the TOA DATA Library (https://www.toa-products.com/international/).
