STA2 Alarm Horn with Xenon &
LED Tower
The STA2 is a customisable audio-visual signal featuring a tower of 2
AlertAlight L101 type beacons combined with a SONF1 alarm sounder.
Each beaco n positio n can contain either a Xenon or high output L.E.D. light source. The STA2
assembly features a pre-wired junctio n box and cable lo o m enabling the end user to determine
beaco n type and po s ition during installatio n.
Features
SONF1 alarm sounder synchronises automatically on multi-unit
systems.
Multiple configurations of Xenon and L.E.D. beacons.
Internal cable loom and termination PCB simplifies installation.
Common negative/neutral supply minimises cabling.
High output L.E.D. unit can be set to steady or flashing.
Available with red, white or grey housing.
Sealed to IP66.
Tropicalisation available on request.
Also available without SONF1 audible signal – see the STB2/3/4
data.
