Asenware AW-CTD322 Two-Wire Conventional Heat Detector

AW-CTD322 Conventional Heat Detector

The Asenware AW-CTD322 Heat Detector is a high-precision thermal sensing device engineered for integration into conventional fire alarm control systems. This unit utilizes a dual-detection methodology, combining fixed temperature thresholds with rate-of-rise thermal monitoring to ensure rapid response to combustion events. It operates on a standard two-wire loop, drawing power directly from the zone circuit. Consequently, it minimizes cabling requirements for large-scale commercial installations. The internal microprocessor analyzes ambient conditions continuously to differentiate between environmental fluctuations and genuine fire threats.

Key Features

• Dual Thermal Sensing Technology
  The device monitors both the absolute temperature and the speed of temperature increases to trigger alarm states efficiently.

• Non-Polarized Wiring Architecture

  • Simplifies field installation by removing polarity requirements on the two-wire loop.
  • Reduces potential for circuit damage during high-volume commissioning phases.

• 360-Degree Visual Indicators
  Dual LEDs provide high-visibility status updates, flashing during standby and remaining latched in red during an active alarm state.

Why Choose Asenware Sensing

• The sensor utilizes SMT (Surface Mount Technology) for enhanced stability and resistance against electromagnetic interference.

• Additionally, the bimetal sensing element provides long-term reliability without the calibration drift associated with lower-tier sensors.

• Therefore, procurement managers can specify this unit for high-density deployments where maintenance overhead must be kept to a minimum.

• This hardware is compatible with most third-party conventional fire panels that support standard 24VDC zone loops.
