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. Key Features: Third-party certified (LPCB) to EN54-3, EN54-23, and EN54-17 [citation:2]; 103 dB(A) sound output @ 1 m; Onboard short-circuit loop isolator for protection and fault tolerance; Quiescent current: ≈ 550 µA; Alarm current: ≈ 14 mA @ 24 V DC (sounder + beacon at full); Group addressing / synchronization function — allows multiple units to operate together under one command; 7 selectable volume levels and up to 15 tone pairs for flexible installation tuning; Deep base design for better wiring access and mounting flexibility; Light distribution rated "W-2.4-8.2" (meets minimum 0.4 lux) when wall mounted; IP rating: The IP55 variant (CON433A/CX/DR/65) is available for weatherproof installations [citation:1]. Industrial Uses / Applications: Office buildings, corridors, stairwells; Hotels, schools, hospitals; Retail / commercial premises; Areas requiring both audible and visual alarms; Installations with addressable fire loop systems; Indoor or semi-protected exteriors [citation:2].
