Cranford Controls VocAlarm Voice Enhanced Sounder
£52.91
Summary
The VOCALARM Voice Enhanced Sounder represents a significant advancement in emergency notification technology, combining traditional alarm tones with clear, digitised voice messaging to improve human response in emergency situations. Each unit is synchronised using a high crystal oscillator to ensure precise timing and coordination across multiple devices.
Clarity is maintained through the use of a high quality digitised voice messaging system that utilises a low current drive circuit for efficient operation. The system offers exceptional flexibility with a growing choice of messages for a wide variety of applications including fire evacuation, security alerts and factory automation, making it suitable for diverse environments where clear communication is essential.
Available in both single message (VCL-01) and dual message (VCL-02) variants, the VOCALARM provides installers with options to suit different application requirements. For two-stage alarm systems, a continuous tone can be added to the VCL-01 model, ensuring compliance with various fire safety protocols and building evacuation procedures.
Each message is preceded by a 6 second sweep tone as standard, in line with BS 5839 requirements, ensuring the system meets British fire safety standards. The robust IP65 rated enclosure makes the VOCALARM suitable for both internal and external installations, whilst the wide operating temperature range ensures reliable performance in challenging environmental conditions.

FAQ
What messages are available for the VOCALARM?
The VCL-01 single message model offers over 30 pre-recorded messages including fire evacuation instructions, security alerts, and factory automation announcements. Popular options include “Fire! Please leave the building” and “Attention! Please leave by the nearest exit”. The VCL-02 dual message model combines two messages such as fire and security alerts for versatile applications.
What is the difference between VCL-01 and VCL-02 models?
The VCL-01 is a single message model that can store and play one pre-selected message, whilst the VCL-02 is a dual message model capable of storing and playing two different messages. The VCL-02 is ideal for applications requiring both fire and security alerts or different evacuation instructions for various scenarios.
What power supply requirements does the VOCALARM have?
The VOCALARM operates on 15-30Vdc with a current consumption of approximately 29mA at 24Vdc. This wide voltage range makes it compatible with most fire alarm system power supplies and ensures reliable operation even with voltage fluctuations.
Can the VOCALARM be used outdoors?
Yes, the VOCALARM has an IP65 protection rating, making it suitable for outdoor installations. It can withstand dust ingress and water jets from any direction. The operating temperature range of -20°C to +70°C ensures reliable performance in various weather conditions.
How loud is the VOCALARM?
The VOCALARM produces 100dBa tone output and approximately 97dBa message output at 1 metre distance when powered at 24Vdc. Volume control allows adjustment down to -25dBa to suit different environments and comply with local noise regulations.
Does the VOCALARM comply with British fire safety standards?
Yes, each message is preceded by a 6 second sweep tone as standard, in line with BS 5839 requirements. This ensures compliance with British fire safety standards and provides the familiar alert tone before voice instructions.
Can I have custom messages recorded?
While the standard range includes over 30 messages covering fire, security and automation applications, custom messages may be available for specific requirements. Contact your supplier to discuss bespoke message options for unique applications.
How is the VOCALARM synchronised with other units?
Each VOCALARM uses a high crystal oscillator for precise synchronisation, ensuring multiple units operate in coordination. This prevents audio interference and provides clear, unified emergency communications across large installations.
