Description The HD201 Mini Addressable Photoelectric Smoke Detector is a compact and intelligent fire detection device designed to deliver early and accurate smoke detection in addressable fire alarm systems. Using advanced photoelectric sensing technology, it effectively detects visible smoke particles produced by smoldering fires while reducing false alarms. This plug-in type detector communicates via addressable analog signaling, transmitting real-time analog data that represents smoke density to the fire alarm control panel. Each detector’s unique address is securely stored in the MCU’s EEPROM and can be easily programmed using a portable address-setting device. The HD201 features dual LED indicators, controlled directly by the control panel, to provide clear visual status for normal operation, fault, and alarm conditions. Engineered for stable performance across varying environmental conditions, this detector requires compatible addressable communication protocols and must be connected only to listed, compatible fire alarm control panels. The HD201 is ideal for commercial, industrial, and residential applications where reliable and precise smoke detection is essential.
