The Context Plus CON446A/CX/DR is a loop-powered addressable sounder that combines alarm tones with clear voice messages, helping occupants understand the alarm and evacuate quickly.
It shares the electronics of the Context Plus wall sounder certified to EN 54-3 and EN 54-17, and draws its power directly from the addressable loop, so no separate power cabling is needed.
Key features:
• Three selectable voice message pairs with high intelligibility.
• 7 selectable volume levels and up to 15 selectable tone pairs.
• Built-in short-circuit loop isolator.
• Group addressing, so several devices can operate together.
• Deep base for surface wiring.
• IP33C (Type B) rating.
• Red housing.
Electrical data:
• Quiescent current: 550µA.
• Alarm current: 10mA at 24V DC with the voice sounder at maximum.
Typical applications:
• Offices, schools and public buildings where spoken instructions improve evacuation.
• Corridors, stairwells and covered plant areas.
