Heat Detector AHR-871

Heat Detector AHR-871


(1) Heat-sensing diaphram can operate for

      unlimited number of times and is not affected

      by room temperature.  The conducting parts

      use gold coating to avoid axidation.

(2) Uses alloy air equalizer to avoid humidity and

      stabilize the ventilation function. Alloy itself has

      many micro-holes that can expel non-fire heat to

      avoid false alarms.

(3) The unit is completely sealed; its function is not

      affected by humidity, dust, or insects.

(4) This detector has passed strict quality control

      through automatic repetitive testing and been

      calibrated automatically under stable temperature

      and humidity conditions. Thus, quality and reliability

      are consistent from the first detector produced to
