Asenware Fire Alarm Heat Detector

Asenware Fire Alarm Heat Detector has two LEDs on each detector providing a local 360° visible alarm indication. They die out when the ambient temperature does not reach the alarm value. If the temperature reaches the alarm value, then the detector enters alarm mode and LEDs light.

Operating Voltage Range: 9 to 28 VDC Volts Non-polarized.

The conventional rate of rising heat detector uses thermal components to detect the temperature changes in the environment. It can enable fire alarm when the temperature difference achieved the setting rate of rising temperature value. It can also enable fire alarm when the absolute temperature value reaches the setting fixed value. It has a stable and reliable working performance.

Maximum Alarm Current(LED on):

Operating Temperature Range: -10℃ to 70℃

Fix Temperature Range: 60℃

Rate of Rising Alarm: 7.1℃/5S

Height: 31.78mm installed in Base

Diameter: 99.45mm
