Combination Smoke and Heat Detector

Combination Smoke and Heat Detector

  • Multi-purpose Design: when there is smoke or heat during pre-fire period, field situation will vary due to different environments. This combination design is to ensure that the pre-fire confirmation will not be affected by varying environments.
  • Smoke gate has a special design to obscure the strong light effectively and allow smoke to come in easily. Water vapor will not gather on the insect guard screen to cause a false alarm.
  • Features an accumulated water discharger to eliminate leakage of water from the water pipes or ceiling which may leak into the detector and cause a false alarm.
  • This detector has passed strict quality control and repetitive testing, hence its quality is stable and highly reliable.
