Description

Conventional Recessed Heat Detector

The Conventional Fire Alarm Heat Detector is engineered to provide early, reliable thermal detection in environments where standard smoke detectors are prone to false alarms, such as kitchens, boiler rooms, and dusty industrial areas. Utilizing a highly stable thermal sensing element, this detector continuously monitors ambient room temperature to identify rapid thermal spikes or fixed high-heat thresholds.

With an adaptable non-polarized wiring design and automatic system reset, it seamlessly integrates into standard 2-wire, 3-wire, or 4-wire conventional fire alarm networks.

Key Features & Performance Advantages

  • High-Efficiency Coverage: Adequately monitors a detecting surface area of up to when installed at a standard ceiling height of 4 meters.

  • Ultra-Low Standby Consumption: Features an incredibly efficient micro-current draw of during normal monitoring conditions ($12\text{-}35\text{V}$).

  • Flexible Wiring Infrastructure: Features non-polarized connection architecture supporting universal 2-wire, 3-wire, or 4-wire configuration schemes for hassle-free field retrofits.

  • Intelligent Auto-Reset Function: Incorporates an automatic alarm reset capability (with an optional 0.5-second power-off reset) to reduce system downtime after testing or activation.

  • Wide Voltage Tolerance: Operates smoothly across a broad DC $10\text{V}$ to $35\text{V}$ power spectrum to protect against voltage fluctuations on the zone loop.
