Description:
The Context Plus CON433A/CX/DR Combined Addressable Sounder & Beacon is a high-performance, loop-powered fire alarm notification device designed to provide both audible warning and visual alarm indication in addressable fire detection systems.
Featuring a powerful 103dB(A) sound output at 1 metre, this combined sounder and visual alarm device (VAD) is suitable for wall-mounted fire alarm notification applications in commercial, industrial and institutional buildings.
The device is LPCB certified to EN54-3 (Sounders), EN54-17 (Short-Circuit Isolators) and EN54-23 (Visual Alarm Devices), meeting recognized standards for fire alarm notification equipment.
Equipped with a high-output flashing beacon, the CON433A/CX/DR provides W-2.4-8.2 light distribution, delivering a minimum illumination of 0.4 lux over a 2.4m × 8.2m cuboid area when wall mounted according to the manufacturer’s specified configuration.
The integrated short-circuit loop isolator helps protect the addressable fire alarm loop by isolating short-circuit faults.
Its group addressing facility allows multiple compatible devices to be activated simultaneously, supporting coordinated alarm notification across different building areas.
The sounder offers 7 selectable volume levels and up to 15 selectable tone pairs, providing flexibility for different fire alarm system requirements.
Operating from a 24V DC addressable loop, the device features a low 550µA quiescent current, helping maintain efficient power consumption during standby operation.
The red deep-base enclosure provides an IP33C (Type B) protection rating, making it suitable for installations that meet the manufacturer’s specified environmental conditions.
Designed for professional addressable fire alarm systems, the Context Plus CON433A/CX/DR is suitable for offices, warehouses, factories, schools, commercial buildings and industrial facilities requiring combined audible and visual fire alarm notification.
