The VF2020 and VF2021 fixed temperature\/rate-of-rise heat detectors are suited to detect in the presence of slow or fast rising temperatures due to burning combustibles.
The construction of these models incorporate a thermistor heat element protected from damage by the built-in, durable plastic guard. These electronic heat detectors incorporate two power\/alarm LEDs for 360\u00b0 indication of status. In standby condition the power LEDs flash Green. In an alarm condition the LEDs latch on Red. The VF2020 and VF2021 electronic heat detection circuitry performs the same function as a Mechanical Device but with Electronic Precision. If the heat rise is less than 12\u00b0\/minute the detector will not alarm until it reaches its alarm temperature (135\u00b0 or 190\u00b0 \u00b1 7.5\u00b0F). If the heat rise is greater than 12\u00b0\/minute the detector will alarm immediately giving an early warning signal and latching the Red alarm LEDs on.<\/p>\n
