The product supports DC 12-24 V input and is engineered for straightforward integration.
Key Features
-
Wide Voltage Compatibility (12–24 V DC) — suitable for both 12 V and 24 V systems for simplified installation across multiple applications.
-
High Sound Output (≈ 105 dB(A) @ 1 m) — loud alert that helps ensure audible notification for occupants in medium-to-large spaces.
-
Low Standby Current Design — keeps loop or panel load minimal, preserving system battery life and reducing wiring cost.
-
Compact and Lightweight (82 × 82 × 33 mm / ~81 g) — easy to mount in tight or retrofit locations without bulky enclosure issues.
-
ABS Housing for Durability — strong plastic casing resists impact and environmental wear, supporting long-term reliability.
-
Temperature Range: –10 °C to +50 °C — reliable operation in typical indoor commercial and light industrial environments.
-
Dual-Use for Fire & Security Systems — can function not only in fire alarm systems but also in intruder / security systems, providing system versatility
Industrial Uses / Applications
-
Conventional fire alarm systems in offices, retail, light industrial facilities
-
Intruder/security alarm systems requiring loud audible alert
-
