The STA and STB towel signals can be configured to include visual and audible signals to create an effective status indicator or warning signal for a range of applications.
The STB tower can be configured with either 2, 3 or 4 Xenon strobe or L.E.D.beacons whilst the STA variant also features a SONF1 type alarm horn sounder capable of up to 100 dB(A) at 1 metre.
The STA/STB tower assembly contains the enclosure, junction box and pre-wired cable loom. The beacon components are ordered separately to meet your individual signalling needs. Pluggable terminals on the L101X Xenon beacon and L101H L.E.D. beacon ensure fast installation and provide the user with the flexibility to sequence colours and light sources as required.
The STA and STB tower signals are designed for high performance and easy installation and are especially
suitable where site staff need to identify the status of an emergency in a
clear and effective way.
