Network Panic Button

ZYCOO PB-S11 Network Panic Button

The ZYCOO PB-S11 is a SIP panic button that places a silent call to preset destinations when pressed. It has a built-in microphone and no speaker, so nothing sounds at the button and the person pressing it does not draw attention. It calls up to five destinations in turn, plays a location message to whoever answers, and runs on PoE through a single network cable.

Works with: any standard SIP server or IP-PBX, including the ZYCOO IP Audio Center.

It suits schools, banks, courtrooms, hospitals, 24-hour restaurants, motels, reception areas, retail shops and car parks, anywhere a staff member may need to raise an alarm quietly. It can also be used for everyday “I need help” calls.

A silent call for help

• No speaker: the button has a microphone only, so the call is concealed. The person at the button is not announcing that help has been called.
• Two activation methods: a single press or a long press, so you can choose which one suits your risk. A long press helps avoid accidental calls.
• Under-desk and counter mounting: the compact unit can be fitted under a desk or counter as well as on a wall.
• LED indicator modes: preset flashing patterns show the button state.
• Adaptive noise reduction: filters background noise so the responder can hear clearly in busy places such as classrooms, factories and stations.

Calls that reach someone

You can set up to five call destinations. If the first is busy, unanswered or offline, the button forwards to the next, so a call is not lost because one person is away from their phone. With a SIP server, it can also dial outbound to external numbers such as security centres, police or medical services.

Works with your phone system

The PB-S11 is a standard SIP endpoint. It registers with any SIP server or IP-PBX as an extension, including the ZYCOO IP Audio Center, and it does not need the IP Audio Center to work. Whoever answers can be on a desk phone, softphone, mobile app or control room console, as long as they are on the same phone system.

A few things are worth checking at design stage:

• Audio codecs: the button supports G.722, G.711 A-law, G.711 u-law and Opus. Your PBX and the receiving phones need to support at least one. G.711 is supported almost everywhere.
• Failover: the five-destination forwarding is handled by the button itself, so it does not depend on PBX ring groups.
• Location message: the voice prompt that plays before the call is answered relies on the PBX passing early media. Test it on your system before sign-off.
• Door control by DTMF: your PBX must pass DTMF tones through to the button, and the door hardware must respond to the relay output.
• External numbers: calling security companies or emergency services depends on your SIP trunk and provider.

Tell the responder where the call is from

A voice prompt can be played before the other end answers. Use the system ringtone, upload your own audio or use a text-to-speech file to announce the location and type of event, for example “Front reception, panic button.” The responder knows where to go before they hear a word from the caller. This is useful on sites with many identical buttons.

Remote door control

Using DTMF tones during the call, authorised staff can lock or unlock doors remotely. A security team could lock classroom doors during an intrusion without leaving the control room. The button also has a dry contact output for relay control of linked equipment.

Built to take abuse

The front panel is 6063 aluminium alloy and the unit is rated IP66 for dust and water, and IK10 for impact. That suits public-facing counters, car parks and any site where the button may be hit, splashed or tampered with. The operating range is -20°C to 70°C.

Installation and integration

The PB-S11 is powered by PoE (IEEE 802.3af/at), so there is no separate power supply. It can be fitted two ways:

• Wall mount: with the EA-MB1 mounting box.
• Flush mount: into a standard 1-gang electrical box.

It uses standard SIP and registers with the ZYCOO IP Audio Center or any third-party SIP server or IP-PBX. It supports three SIP account lines and P2P, and has a flexible API and MQTT. Configuration is through a web interface, or by auto provisioning server.

Specifications

Frequently asked questions

Is the call silent?
Yes. The PB-S11 has a microphone but no speaker, so it makes no sound at the button.

Who does it call?
Up to five destinations that you set. If one is busy, unanswered or offline, it tries the next. With a SIP server it can also call external numbers.

How does the person answering know where the call is from?
A voice prompt plays first. Use the system ringtone, a custom audio file or a text-to-speech file to announce the location or event type.

Can it lock doors?
Authorised staff can lock or unlock doors using DTMF during a call, and the button has a dry contact output for relay control. This needs compatible door hardware.

Does it need a power supply?
No. It is powered over PoE.

Can it be fitted in a standard electrical box?
Yes. It flush mounts in a standard 1-gang box, or wall mounts with the EA-MB1 mounting box.

Is it vandal-proof and weatherproof?
It is rated IK10 for impact and IP66 for dust and water.

Does it work with third-party phone systems?
Yes. It uses standard SIP and works with the ZYCOO IP Audio Center and third-party SIP servers and IP-PBX systems.

Will it work with my phone system?
Yes, if your system is a standard SIP server or IP-PBX. The PB-S11 registers as a SIP extension and calls the destinations you set. It does not need the ZYCOO IP Audio Center. Your PBX needs to support at least one of the button’s codecs (G.722, G.711 A-law, G.711 u-law or Opus).

Do I need a ZYCOO system to use it?
No. It works with third-party SIP servers and IP-PBX systems as well as the ZYCOO IP Audio Center.

Can the person answering be on a normal phone?
Yes. Any SIP phone, softphone or console registered to the same PBX can receive the call.

Does the door lock feature work on any PBX?
It needs a PBX that passes DTMF tones through, plus compatible door hardware. Test it on your system.
