Removable, High Performance chamber Automatic Sensitivity Window Verification (ASWV) – Drift Compensation Technology Remote Indicator output Wide voltage range (9.5 ~ 30 V dc) Low profile design with one-piece outer cover Single fire LED - 360° viewing Range of mounting bases Approved by LPCB; Quality – High quality products ensures long term reliability Flase Alarm Reduction – Hoghiki’s conventional range uses advanced verificaition techniques to reduce the potential for false or unwanted alarms. In addition, the Photoelectric Smoke Detectors operate on very low sensitivty, yet exceed the requirements of the EN54 standard to minimise false alarms. Approvals – Hochiki’s conventional products are tested and approved to the latest standards and regulations by the major European third party test bodies, including LPCB and VdS. Simple Installation – Simple installation, integration and therefore cost minimisation is achieved through special bases integrated on the same set of cables. Integration and Cost Minimisation – Using a number of special bases, and through integration detection and evacuation devices on the same set of cables, the lowest cost of installation and ownership are achieved. Low current consumption and the capability of integration into security systems further reduce ownership costs. Compatibility – Development in alliance with independent panel manufactures ensures that functions and benefits of the Hochiki Conventional Detection range are incorporated, and rigorous testing confirms compatibility and compliance. Locking Mechanism – The Hochiki Conventional range has been designed for ease of installation, with a wide range of bases, and adapters, and a locking mechanism on all detectors for on-site activation. Simple and Robust – Simple and robust connections provide sufficient space for all modern fire alarm cables.
