Description
The Siemens OH720 (Part Number: S54310-F2-A1 / Cerberus PRO Series) is a reliable multi-criteria addressable detector engineered by Siemens Building Technologies for commercial, industrial, and institutional fire safety applications. By integrating an optical light-scattering smoke sensor with an electronic thermistor heat sensor within a low-profile housing, the device evaluates both particulate density and temperature changes simultaneously. Its internal microprocessor uses intelligent signal evaluation to respond rapidly to both fast-flaming fires and slow-smoldering blazes while rejecting deceptive environmental sources such as steam, dust, or electrical interference. Operating on Siemens Cerberus PRO addressable loops (C-NET), the unit features automatic soft addressing, an integrated short-circuit loop isolator, 360-degree LED status indication, dynamic drift compensation, and full VdS, LPCB, and EN 54 approvals.
Features
- Dual Opto-Thermal Sensing: Combines an optical forward-scattering sensor with a supplementary heat sensor for rapid detection of smoldering and flaming fires.
- High False Alarm Immunity: Employs built-in signal processing algorithms to analyze optical and thermal inputs, preventing false alarms from dust and environmental noise.
- Integrated Line Separator: Built-in short-circuit isolator isolates shorted loop segments automatically to protect system communication integrity.
- Central 360-Degree LED Indicator: Incorporates a central status LED for clear omnidirectional visual polling and alarm status verification.
- Auto-Addressing Protocol: Simplifies commissioning with automatic address allocation via the C-NET loop software.
