Cranford Controls launches new 12V sounder, strobe and combination units for fire and security systems 
(07/03/2006)
For use in security systems and other 12VDC applications, Cranford Controls has introduced 12 Volt versions of its well-established 24VDC Vantage fire sounder, strobe and combination audible-visual units. The two stage sounders have 32 selectable tones, with variable outputs from 91dB(A) to 111dB(A) at 1m, selectable via an on-board DIL switch.
The sounders offer a wide frequency range from 400 to 2950Hz and a combination of advanced electronics, a high performance transducer and efficient folded horn design ensures that they are highly capable devices, particularly at the higher frequencies more often used in security applications. The beacons, available with red, amber or clear lenses, can be hard-wired to give either 0.7W or 0.4W output; they draw only 10mA or 6mA at 12V, minimising the load on the control panel and potentially reducing the size of the battery back-up required.
The compact units are available in red or white, sealed to IP43 for indoor use or IP65 for external applications. The enhanced environmental protection is achieved by using a deep mounting base as an alternative to the standard base.
In both versions, the unit is assembled into the base using a bayonet fixing arrangement and can be locked into place using a security grub screw if required. The separate base enables the majority of the installation work to be carried out at the first fix stage, with the devices themselves added during the commissioning phase.
The 12V and 24V versions of the Vantage are identical in appearance, enabling a uniform look across the fire and security systems to be achieved throughout the protected premises.
