BLASI – Piezo Sounder 6-28VDC (Siren)
The BLASI Piezo Sounder 6-28VDC (Siren) is a high-output audible alarm integrated into automatic revolving door control systems. This wide-range piezoelectric siren generates piercing 105+dB warnings triggered by the TA-4 logic board for safety alerts, emergency conditions, and operational status notifications. Operating across 6-28VDC input ensures reliable performance during battery backup and mains power fluctuations. Weatherproof IP65 construction withstands entrance environment humidity and cleaning chemicals while direct mounting to distribution panels provides immediate audible coverage essential for passenger safety communication in commercial facilities.
Product Details
The BLASI Piezo Sounder delivers continuous 105-110dB output across 1500-3500Hz siren sweep specifically engineered to penetrate ambient entrance noise while remaining comfortable for prolonged exposure. Wide 6-28VDC operating range eliminates voltage sensitivity issues common during battery failover while low current draw (30-150mA typical) preserves emergency reserve capacity for extended outage operation.
Direct activation from TA-4 controller alarm outputs coordinates with visual indicators and safety interlocks, providing multi-modal hazard notification during emergency stops, safety edge faults, and system malfunctions. Precision frequency modulation creates distinctive rising/falling siren pattern immediately recognizable as door system alert rather than generic fire alarm.
Robust ABS or polycarbonate housing with stainless steel mounting hardware resists corrosive cleaning agents and mechanical impact. Field-replaceable design enables rapid siren restoration while maintaining circuit integrity. Essential for regulatory compliance requiring audible safety communication in hotels, hospitals, office buildings, and retail facilities where clear warnings prevent accidents during peak occupancy and emergency conditions.
