GP6, GP10 and GP12 Sirens

INSTALLATION AND MAINTENANCE

1.Installation

a.Fix siren to a firm level base at a minimum height of 3m above the ground and free of side or top obstructions.

b.For best all round sound propagation mount the unit at a height of 4.5 to 6m with 50m clear radius all round.

c.Figure 1 overleaf shows a polar plot of the sound output from the sirens in free space.

Please note that the propagation of sound in air is affected by the following factors which must be accounted for when calculating the coverage of the siren:

Variations of the propagation speed in the air

Attenuation of the sound during propagation

Wind and turbulence of the atmosphere

Obstacles placed in the vicinity of siren and listener.

Ambient noise levels

d.The plot assumes ideal free-field conditions.

The following losses must be taken into account during commissioning:

Sound attenuation loss over distance in free-field conditions without obstructions.

Attenuation in decibels per kilometre due to absorption of sound in air (10°C, 90%RH).

At 500 Hz frequency the attenuation is 1.6 dB(A)/kilometre

Absorption due to fog in decibels per kilometre.

At 500 Hz frequency the attenuation is 1.0 dB(A)/kilometre

The two figures provided for sound absorption in clear air and fog are sound losses in addition to the typical sound losses experienced over distance indicated in the table above.

GP12, GP6, GP10 specifications

The Klaxon GP series, comprising the GP10, GP12, and GP6 models, represents a pinnacle in acoustic signaling technology, renowned for their robustness and high performance under diverse working conditions. Each model within this range is engineered to offer reliable auditory alerts in various industrial and commercial settings.

The GP10 is designed for environments that require a dependable sound output with minimal power consumption. Its unique polycarbonate housing allows it to withstand harsh weather conditions, making it suitable for outdoor applications. The GP10 features a double-tone signaling capability, providing flexibility in alert types. Furthermore, it operates with high efficiency, ensuring a long operational life with reduced maintenance needs.

The GP12 takes the feature set of the GP10 a step further by incorporating advanced sound projection technology, which enhances audibility across extended ranges. This model is particularly favored in large industrial complexes and buildings where sound needs to travel far without losing clarity. The GP12 also includes adjustable volume settings, allowing users to tailor the sound levels according to specific environment requirements. Its integrated LED indicators provide visual alerts, making it an excellent choice for multi-sensory signaling.

On the other hand, the GP6 model is compact yet powerful, aimed at applications where space is at a premium. Despite its smaller footprint, the GP6 does not compromise on sound output, delivering clear and penetrating alerts that can be heard over considerable distances. This makes it an ideal choice for machinery and equipment that require quick notifications. Like its counterparts, the GP6 is also built from durable materials, ensuring it can endure tough industrial conditions.

All models in the Klaxon GP series embrace cutting-edge technologies such as digital sound generation, which leads to improved sound quality and reduced distortion. These devices are also designed for compatibility with various control systems, accommodating a wide array of signaling and alarm requirements. With their high ingress protection ratings, they offer excellent resistance to dust and moisture, further enhancing their suitability for outdoor and challenging environments.

In summary, the Klaxon GP10, GP12, and GP6 each bring unique features and technologies to the table, catering to diverse signaling needs. Their durability, sound reliability, and adaptability make them essential tools for enhancing safety and communication across various fields.
