AW-D302
Addressable Heat Detector
The AW-D302 is an addressable heat detector designed for use with the AW-FP300 fire alarm control panel. Equipped with a built-in microprocessor, it provides real-time temperature data and electronic addressing for efficient fire detection in smart systems.
It is particularly suited for locations where smoke detectors may be unreliable, such as kitchens, boiler rooms, generator rooms, drying workshops, and smoking rooms. It is not recommended for places with a lot of smoke but little heat.
Suitable Applications
This detector is suited for environments where standard optical smoke detectors might cause false alarms due to high ambient dust, steam, or ambient smoke, but high heat generation indicates an active fire:
- Kitchens and boiler rooms
- Generator rooms and electrical switchrooms
- Drying workshops and smoking areas
Key Features
- Microprocessor Control: Features a single-chip microcomputer for real-time temperature data acquisition, signal processing, and sensor fault monitoring.
- Electronic Coding: Addresses can be coded and rewritten in situ using an external programmer (supports addresses 1 to 324).
- Two-Wire Non-Polarity Connection: Uses a polarity-insensitive two-bus loop for straightforward wiring and maintenance.
- Visual Status Indicator: A red LED flashes during normal polling and remains continuously lit during an alarm state.
- Remote Indicator Support: Equipped with output terminals to power an optional remote LED indicator upon alarm activation.
- Modular Design: Built with a detachable upper/lower enclosure that mounts onto an independent base for easy installation and debugging.
