Product Name: LONDEX Alarm Annunci
Product Description
The LONDEX Range of Alarm Annunciators were acquired by RTK Engineering Ltd in 1996 and have been extensively used in all industry types but are very common within Sub Station & Turbine applications due to its historical connection with GEC, Ruston Gas Turbines & Cambridge Instruments.
The Londalert 32 & Londalert 4 are fully integrated 32 channel General Purpose Alarm Annunciators that are suitable for 19" or Flush Panel mounting. The display fascia's offer differing ergonomic solutions but the features are largely common.

Integral Common Horn & Common Alarm Relays.
