STA2 LED Alarm Tower 230vAC with Sounder SONF1 and Junction Box,  
 fully assembled with Red & Amber LED Beacon Elements (listed from top)  
   
 The STA2, STA3 and STA4 are customisable audio-visual signals featuring a tower of 2, 3 or 4 AlertAlight L101 type beacons combined with a SONF1 alarm sounder.  
 Each beacon position can contain either a Xenon or high output L.E.D. light source. The STA2, STA3 or STA4 assembly features a prewired junction box and cable loom enabling the end user to determine beacon type and position during installation.  
  
 Features:
 • SONF1 alarm sounder synchronises automatically on multi-unit systems.
 • Multiple configurations of Xenon and LED beacons.
 • Internal cable loom and termination PCB simplifies installation.
 • Common negative/neutral supply minimises cabling.
 • High output LED 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 sheet (2.1.021v10a).
