Visual and audible-visual warning signal towers
28 August 2012
E2S has introduced the IP66 sealed STA and the STB user-configurable warning towers. The construction is modular, consisting of a separate termination enclosure fitted with two M20 cable entries and up to five unpopulated housings.
The assembly is available in a choice of grey, red or white. 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 24Vdc and 115 and 230Vac. 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.
