Grandstream SIP-based GSC3506 v2 multicast paging speaker

Grandstream GSC3506v2 multicast paging speaker - distributed by TeleDynamics

The Grandstream GSC3506 v2 is a versatile multicast paging speaker designed to provide effective paging and public address capabilities, enhancing security and communications in environments like offices, schools, hospitals, apartments, and more.

In this article, we explore the capabilities of this innovative device and highlight some of its most impressive features.

Paging systems

For too long, organizations have been relying on outdated analog public address (PA) systems to fulfill their paging needs. These systems require the often-complicated integration of more advanced unified communications (UC) systems with older analog technologies due to PA systems lagging behind in the leveraging of more advanced technologies. Some more modern PA systems that are based on VoIP and SIP still use analog speakers, requiring running speaker cables to the appropriate locations throughout your facilities.

Grandstream’s solution

Grandstream helps organizations overcome the challenges involved with PA systems by delivering its newest SIP-based PA system speaker, the GSC3506 v2. As part of Grandstream’s facility management portfolio, this device can be connected to the facility’s structured UTP cabling, which is used for all types of network devices. The GSC3506 v2 can be connected to the same network infrastructure as IP cameras, wireless access points, and IP telephones, becoming part of Grandstream’s UC and facility management ecosystem.

The GSC3506 v2 speaker

Equipped with a 30 W high-fidelity high-definition (HD) speaker, this high-performance SIP speaker provides crystal-clear HD audio. It supports SIP and multicast paging, group paging, and push-to-talk (PTT), and it features built-in whitelists, blacklists, and graylists for easily managing unwanted calls. With its sleek design, robust HD speaker, seamless integrations, and advanced functions, the GSC3506 v2 enables users to implement a cutting-edge security and paging system in any setting.

As the newest iteration of the product after the GSC3506 v1, the v2 incarnation retains the same form factor as its predecessor while introducing new features such as PoE++ support, a three-pin differential line-out port, a more powerful speaker capable of up to 99 dB, and expanded memory (256 MB of RAM). When integrated with other Grandstream products, such as desktop and cordless IP phones, facility access systems, network switches, and IP PBXs, the GSC3506 v2 enables users to easily build a cutting-edge security paging and PA solution.

Key features

Here are some of the most noteworthy features of the device:

A 30W high-fidelity speaker with HD acoustic chamber
Support for SIP paging, multicast paging, and call waiting with priority override
Support for full-band and wide-band audio codecs, including Opus and G.722
Auxiliary ports:
- 1× 3-pin differential line out port
- 1× 2-pin switch-in input
- 1× alarm-in input
- 1× 24 V DC for local power provisioning
- 1× 10/100 Mbps network port with PoE/PoE+/PoE++
- 1× USB port for external storage
Volume up/down and reset keys

Versatility of deployment

The GSC3506 v2 features a wide range of ports that make it a highly versatile component of your overall PA system:

The two-pin differential line output port is used to send audio signals to an external amplifier or speaker system. It essentially reproduces whatever sound is being played by the local speaker and sends it to an analog system. This is useful if you want to further amplify the sound or distribute it further throughout your facilities using an external sound system.
The two-pin switch-in input port can be used to connect an external switch or sensor to trigger an action. For example, it could be connected to a door sensor, panic button, or any other contact-closure device. When the switch is activated (opened or closed), the GSC3506 v2 device can respond by initiating an event, such as sending a page, triggering an alarm, or carrying out another automated response.
The alarm-in input is similar to the switch-in input but is specifically used with external security systems and devices, including motion detectors, door sensors, smoke detectors, or other safety systems. When an external alarm device is triggered, the alarm-in input can activate the predefined alarm action on the GSC3506 v2, essentially allowing the device to participate as an alarm notifier. This feature is particularly useful for integrating the speaker into larger security systems, allowing it to respond automatically to real-time events.

Conclusion

The GSC3506 V2 stands out as a first-rate solution for enhancing security and communications across a wide range of environments. With its upgraded features—including PoE++ support, a powerful 99 dB speaker, expanded memory, and advanced connectivity options like SIP and multicast paging—it offers users the flexibility to create an efficient and seamless public address and security system. Whether integrated with other Grandstream devices or used independently, the GSC3506 v2 delivers crystal-clear audio and reliable performance, making it an ideal choice for offices, schools, hospitals, and much more.
