Description

The Asenware AW-303 (AW-D303) is an intelligent addressable multi-sensor fire detector engineered for commercial, industrial, and institutional fire alarm systems. Combining an optical photoelectric chamber with dual electronic heat sensors within a low-profile housing, the detector provides multi-criteria verification to detect fast-flaming fires and smoldering smoke while rejecting transient false alarms. Managed by an internal single-chip MCU executing dynamic curve-tracing algorithms, the unit features dynamic drift compensation for dust accumulation, automatic fault monitoring, and electronic handheld coder addressing. Operating on a non-polarized 2-wire 24V loop, it provides 360-degree visual LED indication, remote indicator driver outputs, and compliance with EN 54-5 and EN 54-7 standards.

Features

  • Dual-Sensing Combination Technology: Integrates an optical photoelectric chamber with dual thermal sensors to detect both smoke particles and rapid or fixed temperature increases.
  • Single-Chip Microprocessor Control: Uses an embedded single-chip MCU to collect real-time ambient data, process complex signal curves, and provide dynamic drift compensation for dust accumulation.
  • Dynamic Rejection Algorithm: Features advanced signal filtering software that suppresses transient environmental disturbances to maintain target sensitivity while avoiding false alarms.
  • Electronic Field Soft Addressing: Allows fast, flexible assignment of loop addresses from 1 to 324 using an electronic handheld coder without relying on physical DIP switches.
  • Non-Polarity Two-Wire Loop Connection: Connects using a non-polarized 2-wire loop interface to ensure fast, fault-free installation and easy system maintenance.
  • Built-In Remote Indicator Terminal: Includes an integrated output port to directly drive an external remote LED indicator located above doors or inside concealed spaces.
