CONTEXT PLUS CON433A COMBINED ADDRESSABLE SOUNDER AND BEACON 103 DB DEEP BASE

Description

The CON433A/CX/DR is a loop-powered, addressable combined sounder + visual beacon unit with a deep base, designed for fire alarm systems. It carries LPCB certification and complies with EN54-3 (sounders), EN54-23 (visual alarm devices), and EN54-17 (isolators) when used with the matching base.

When wall-mounted, it provides a “W-2.4-8.2” light distribution — delivering at least 0.4 lux over a 2.4m × 8.2m area. 

It employs the same lens and electronics used in Context’s Hi-Output Sounder VAD series, ensuring high reliability in both audible and visual signalling.
