The SE-804P is a high-output piezoelectric siren designed for use with fire alarm systems, intruder alarm panels, and other security/alert systems. It features a loud sound level (≈105 dB) and a compact, lightweight ABS plastic housing, making it suitable for surface-mounted installations in commercial or industrial environments. 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; Surface-mounted installation in corridors, machine rooms, storage areas; Retrofit projects replacing older horn/sirens where higher SPL and compact footprint are needed; Areas where moderate ambient noise requires a siren with strong output.
