C-TEC CAST Invacuation Wall Voice Sounder | Multi-Message Lockdown Speaker | White/Red, 92dB(A)
£54.09
Summary
The C-TEC CA446A/DW/LD CAST Invacuation/Lockdown Wall Voice Sounder is a powerful wall-mounting notification device specifically designed for use on C-TEC CAST lockdown and invacuation systems. Delivering high-output voice messages with superb sound intelligibility, this sounder provides clear, authoritative instructions to building occupants during security incidents, ensuring they understand the appropriate response to different levels of threat.
Designed to help venues comply with The Terrorism (Protection of Premises) Act 2025, also known as ‘Martyn’s Law’, this device can sound multiple pre-recorded voice messages to suit different threat scenarios. When used as part of a dedicated LAP2/CA multi-message lockdown alert system or integrated into a combined C-TEC ZFP CAST protocol fire alarm/lockdown system, the sounder can deliver five distinct messages covering full lockdown, partial lockdown, evacuation, and all clear situations. For simpler applications, it can also be used with the LAP501/CA single-message lockdown alert system to sound a full lockdown message.
The device features a nominal sound pressure level of 92dB(A) at 1 metre, ensuring messages are clearly heard throughout the protected area even in environments with ambient noise. Four selectable volume levels allow the output to be tailored to the specific acoustic requirements of different spaces, from small rooms to larger open areas. The superb sound intelligibility ensures that voice messages are not only loud enough but also clear and understandable, which is critical for effective communication during high-stress emergency situations.
Available in both white and red finishes to match different interior schemes or provide visual differentiation within the building, the CA446A/DW/LD features robust construction with an IP33C (Type B) rating for reliable indoor operation. The device includes an onboard short-circuit loop isolator to protect system integrity, group addressing capability for simultaneous operation of multiple devices, and exceptionally low power consumption with just 470µA typical quiescent current. Custom or coded voice messages can be arranged by special order, making this an adaptable solution for schools, theatres, shopping centres, and other commercial and public venues requiring Martyn’s Law compliance.

FAQs
What is the difference between the CA446A/DW/LD and the CA447A/DW/LD?
The CA446A/DW/LD is a voice sounder only, while the CA447A/DW/LD is a voice sounder VAD (Visual Alarm Device) that includes a blue-flashing beacon. Both devices deliver the same five voice messages with 92dB(A) output, but the VAD version provides additional visual notification for occupants who are deaf, hard of hearing, or in high-noise environments. The CA446A/DW/LD has a lower alarm current (15.5mA vs 26.5mA) and is lighter (300g vs 315g).
What voice messages are included with the CA446A/DW/LD?
The device includes five pre-recorded messages: Message 1 for full lockdown (immediate internal threat), Message 2 for partial lockdown (internal threat), Message 3 for partial lockdown (external threat), Message 4 for full evacuation, and Message 5 for all clear when the situation is resolved. When used with the LAP2/CA multi-message panel, all five messages can be triggered. With the LAP501/CA single-message panel, only Message 1 (full lockdown) is available.
Can I customize the voice messages?
Yes, custom or coded voice messages can be arranged by special order. This allows venues to tailor messages to their specific emergency procedures, use coded language for discretion, or provide messages in multiple languages. Contact C-TEC’s lockdown system support team at lockdown@c-tec.co.uk for more details about custom message options.
What systems is the CA446A/DW/LD compatible with?
The device is compatible with C-TEC’s CAST protocol addressable fire panels, including the dedicated LAP2/CA multi-message lockdown alert panel, the LAP501/CA single-message lockdown alert panel, and any ZFP CAST-protocol addressable fire alarm system. It operates on 27 to 40V DC supply voltage.
How loud is the voice sounder and can the volume be adjusted?
The CA446A/DW/LD produces a nominal sound pressure level of 92dB(A) at 1 metre, which is sufficient for clear message delivery in most indoor environments. The device features four selectable volume levels, allowing you to adjust the output to match the acoustic requirements of different spaces, ensuring messages are audible without being excessively loud in smaller areas.
What is superb sound intelligibility and why is it important?
Sound intelligibility refers to how clearly and understandably speech can be heard. The CA446A/DW/LD is designed to deliver not just loud messages but also highly intelligible ones, meaning occupants can clearly understand every word even in stressful situations or environments with ambient noise. This is critical during emergencies when clear communication can make the difference between effective response and confusion.
Can multiple sounders be operated simultaneously?
Yes, the CA446A/DW/LD features a group addressing facility that allows multiple devices to be operated simultaneously across the building. This ensures consistent message delivery throughout the premises and creates a coordinated response during lockdown situations, with all sounders broadcasting the same message at the same time.
What is the onboard short-circuit loop isolator?
The onboard short-circuit loop isolator is a safety feature that protects the integrity of the CAST protocol loop. If a short circuit occurs at the sounder or in the wiring connected to it, the isolator automatically isolates that section of the loop, preventing the fault from affecting other devices on the system and maintaining the functionality of the rest of the lockdown alert network.
Is the device suitable for outdoor installation?
No, the CA446A/DW/LD is designed for indoor areas only. While it has an IP33C (Type B) rating providing protection against solid objects greater than 2.5mm and water spray at an angle up to 60°, it is not weatherproof and should only be installed in indoor environments within the operating temperature range of -10°C to +55°C.
What colour options are available?
The CA446A/DW/LD is available in both white and red finish options. The choice of colour can be based on interior design preferences, the need to match existing fire safety equipment, or to provide visual differentiation between different types of notification devices within the building.
How does this device help with Martyn’s Law compliance?
Martyn’s Law (The Terrorism Protection of Premises Act 2025) requires premises with a capacity of 200 or more to have public protection measures, including lockdown plans, in place by April 2027. The CA446A/DW/LD provides the audible notification component essential for effective lockdown procedures, delivering clear voice instructions to building occupants about the appropriate response to different threat scenarios.
When will the CA446A/DW/LD be available?
The device is scheduled for release in Q4 2025. For specific availability dates and to place pre-orders, contact C-TEC’s sales desk directly.
