6. AUDIO VISUAL PRODUCTS

KAC Sounders and Strobes from simple tone set conventional products to fully featured fourteen-tone intelligent units, a range of sounders, strobes and combined sounder-strobe products suitable for all applications.

The range meets the requirements of EN54 Part 3; key products are LPCB and VdS Approved. All are fully tested under simulated climatic conditions to ensure “real-world” conformance to the published specifications.

SOUNDERS

KAC Sounders are available in four or fourteen-tone versions. They operate at 9-33VDC, optimised for use at 12 and 24 volts. Four tone sounders have a high, medium and low volume selection, whilst the fourteen tone sounder has a volume control.

The sounders have a distinctive, acoustically efficient low profile shape, producing high sound output at low current levels. The shape provides a wide-angle uniform sound distribution providing good audibility in all directions.

The sounders are of rugged construction with solid-state electronics providing high reliability and stable performance. Three bases are available: low profile IP44, IP55 or IP66.

DETECTOR BASE SOUNDERS

KAC Detector Base Sounders are for use either underneath smoke detectors or fitted with a red or white lid as a low profile wall mounted sounder. They are available in four or fourteen tone versions. They operate at 9-33VDC (nominally 12 and 24 volt). Four tone sounders have a high, medium and low volume selection, whilst the fourteen tone sounder has a volume control.

The package is acoustically very efficient, producing omni- directional high sound output with low current levels. The detector base sounder can be used under any smoke detector with 60mm mounting centres and an external diameter of up to 102mm.

STROBES

The KAC Range of stand-alone Strobes is designed to provide visual signalling for use in a wide range of applications. There are both standard and high intensity output strobes available. A variety of different coloured strobe lenses are available.

This variety of colours provides a range of products for different applications.

SOUNDER STROBES

The KAC Sounder Strobe combines a full feature fourteen-tone sounder with an integral strobe mounted on the horn. The design provides an efficient combination of audible and visual warning, in a package taking up no more surface area than a standard sounder.

A variety of different coloured strobe lenses are available and the product housing is available in either red or white.

BASES

Three bases are available for KAC Sounders and Sounder Strobes. The standard base is an IP44 rated low profile unit. The base has rear and side cable access suitable for use with standard trunking and has mounting holes suitable for the

majority of back box formats.

A deeper profile base with knockouts and marked drilling positions for rear and side entry allows for an IP55 rating, when used with appropriate glands.

The IP66 base has the same features as the IP55, but includes a sealing kit to increase the protection rating.

BS5839 specifications

System Sensor BS5839 is a standard that pertains to fire detection and alarm systems, providing guidelines for the design, installation, and maintenance of these essential safety tools. It is crucial for safeguarding lives and property, ensuring that fire detection systems are effective and reliable. The BS5839 standard, established in the UK, covers a wide range of fire alarm system types, including conventional, addressable, and wireless systems.

One of the main features of BS5839 is its comprehensive classification of fire detection systems. The standard divides systems into categories based on the level of risk and the environment in which the system will operate. This classification helps ensure that the system installed meets the specific needs of the building and its occupants. For example, Category L systems are meant for life safety, while Category P systems are designed to protect property.

The technologies underpinning BS5839 include various types of detectors, alarm devices, and control panels. Smoke detectors, heat detectors, and multi-sensor detectors are prominent among the devices specified in the standard. Smoke detectors use photoelectric or ionization principles to detect smoke and signal an alarm, while heat detectors respond to temperature changes. Multi-sensor detectors combine both smoke and heat detection technologies to provide a more reliable response to fire conditions.

Another key characteristic of BS5839 is the emphasis on regular testing and maintenance. The standard outlines procedures to ensure that systems remain operational and effective over time. This includes routine system checks, functional testing, and more in-depth inspections at regular intervals. Ensuring that systems are maintained according to BS5839 is vital for compliance with insurance requirements and for safeguarding against potential legal liabilities.

Furthermore, BS5839 highlights the importance of staff training and awareness. It emphasizes that personnel responsible for fire safety must be adequately trained in the operation and response to fire alarm systems. This ensures that in the event of a fire, occupants are prompted to take appropriate action and evacuate safely.

In summary, System Sensor BS5839 provides a crucial framework for fire detection and alarm systems. Its classification of systems, incorporation of advanced technologies, and emphasis on maintenance all contribute to enhanced safety and compliance, protecting lives and property effectively.
