C-TEC CAST Invacuation Wall Voice Sounder VAD | Multi-Message Lockdown Speaker with Blue Strobe | White
£72.11
Summary
The C-TEC CA447A/DW/LD CAST Invacuation/Lockdown Wall Voice Sounder VAD is a powerful wall-mounting notification device specifically designed for use on C-TEC CAST lockdown and invacuation systems. Combining high-output voice message capabilities with a blue-flashing Visual Alarm Device (VAD), this sounder provides both audible and visual alerts to ensure building occupants receive clear, unmistakable lockdown instructions during security incidents.
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 levels of threat. 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 scenarios. 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 superb sound intelligibility with a nominal sound pressure level of 92dB(A) at 1 metre, ensuring messages are clearly heard even in noisy environments. Four selectable volume levels allow the output to be tailored to the specific acoustic requirements of different spaces. The integrated blue-flashing VAD beacon provides essential visual notification for occupants who are deaf, hard of hearing, or in high-ambient-noise environments, while also serving as an instantly recognisable visual indicator that differentiates lockdown alerts from fire evacuation alarms.
Available in both white and red finishes to match different interior schemes or provide visual differentiation, the CA447A/DW/LD features robust construction with an IP33C (Type B) rating for reliable operation. The device includes an onboard short-circuit loop isolator to protect system integrity, group addressing capability for simultaneous operation of multiple devices, and 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 a voice sounder and a voice sounder VAD?
A voice sounder VAD (Visual Alarm Device) combines both audible voice messages and visual signalling in one unit. The CA447A/DW/LD includes a blue-flashing beacon that activates during lockdown situations, providing visual notification for occupants who are deaf, hard of hearing, or in high-noise environments. The blue colour also helps differentiate lockdown alerts from red fire evacuation beacons, reducing confusion during emergencies.
What voice messages are included with the CA447A/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 have custom voice messages recorded?
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 CA447A/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?
The CA447A/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, from small rooms to larger open areas.
What does the blue VAD beacon indicate?
The blue-flashing VAD beacon activates specifically during lockdown situations, providing an instantly recognisable visual indicator that differentiates lockdown alerts from fire evacuation signals (which typically use red beacons). This colour differentiation helps prevent confusion and ensures occupants understand whether they should evacuate the building or move to secure areas within it.
Can multiple sounders be operated simultaneously?
Yes, the CA447A/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.
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 CA447A/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 CA447A/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.
When will the CA447A/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.
