Visual and audible-visual warning signal towers

A STA audible-visual unit consists of up to four high-performance L101 beacons and a 100dB(A) SONF1 10-tone sounder; the STB version has up to four beacons without the sounder. A pre-configured wiring loom interconnects the housings, enabling the units to be easily populated and configured as they are installed on site.

The units are designed for use in fire and gas systems and as a general-purpose indicator for industrial use in applications such as machine alarms, security systems and any application where a loud audible or audible-visual warning signal is required. The sounder generates the three UKOOA/PFEER standard tones, allowing it to be installed in non-hazardous areas such as accommodation modules and canteens in onshore and offshore facilities.

The beacons are available as either 200cd Xenon strobe units or 120cd high intensity LED units, both with a choice of amber, blue, clear, green, magenta, opal, red or yellow lenses. The two-stage sounder has an effective range of 30m at 1kHz. Nominal operating voltages are 12 and 24V DC and 115 and 230V AC. The units can be wall or bulkhead mounted using external lugs or secured directly to a standard conduit box through the rear face of any of the housings.
