- Rate Of Rise Heat DetectorThe 2020R incorporates both rate of rise and static elements, using a heat element with an ASIC.
- EN54 Class A1R ApprovalIt is approved as Class A1R to EN54 - 5:2000 (Amendment 1) and declared against EN 54-5: 2017 + A1: 2018.
- DOP-CFD018 Cat A1RIts designation is DOP-CFD018 Cat A1R, and the certification body numbers are 0832 22 and 2831 05.
- Low Standby CurrentThe maximum standby current is 70μA @ 24VDC at 25ºC and quiescent draw is 55 µA Typical, at 24 VDC, 25°C.
- Ambient Limit For A1RThe ambient operating temperature ceiling is 45ºC, above which class A1R detectors may be triggered into unwanted alarm conditions.
- Requires Compatible Control PanelHeat sensors will only work when connected to a functioning, compatible control panel.
- Low Profile ABS HeadThe ABS housing approximates RAL9016 and measures 102mm in diameter, standing 40.5mm tall before a standard base adds 9.5mm.

Description
The 2020R sits in the Vision conventional range as its rate of rise heat option, built on a heat element and ASIC that carry both rate of rise and static sensing. Class A1R approval under EN54 - 5:2000 (Amendment 1) is accompanied by a declaration against EN 54-5: 2017 + A1: 2018. The designation DOP-CFD018 Cat A1R applies, and the certification body numbers are 0832 22 and 2831 05.
The ceiling attached to Class A1R is plain: the maximum ambient operating temperature for such detectors is 45ºC, beyond which unwanted alarm conditions may be triggered. Heat sensors will also only work when connected to a functioning, compatible control panel, so every component in the detection system must be known-compatible.

On the line it takes 14 - 28 VDC and 55 µA Typical, at 24 VDC, 25°C, latching in alarm until a momentary power interruption resets it. Terminals accept 0.4mm2 to 2.0mm2 conductors. Standard bases (2020B, 2020BSD) and deep bases (2020DB, 2020DBSD) can be used with it, and the 2020LT laser tool triggers it remotely from several metres.
The 2020R is the rate of rise heat detector in the Vision range of conventional detectors, its heat element and ASIC incorporating both rate of rise and static elements for quick and accurate detection of fires. It carries Class A1R approval to EN54 - 5:2000 (Amendment 1), a declaration against EN 54-5: 2017 + A1: 2018 and the designation DOP-CFD018 Cat A1R. LPCB and CE approval is held for the detector.
The supply is 14 - 28 VDC, nominal 24VDC. Quiescent draw is 55 µA Typical, at 24 VDC, 25°C, the maximum standby current is 70μA @ 24VDC at 25ºC and the maximum alarm current is 70mA @ 28VDC. Alarms latch until reset by a momentary power interruption, indicated by the integral LED, with an optional remote LED annunciator to repeat the signal.
Environmental limits run from -30ºC to +70ºC at 5 to 95% Relative Humidity (non-condensing), but ambient operating temperature at a class A1R detector should not exceed 45ºC if unwanted alarm conditions are to be avoided. The low profile ABS head approximates RAL9016 at 102mm diameter and 40.5mm height, a standard base adding 9.5mm, and weighs 70g with 45g for that base.
Heat sensors will only work when connected to a functioning, compatible control panel, and it is essential that only known compatible components go into the detection system. A variety of bases serves the detector - 2020B, 2020BSD, 2020DB and 2020DBSD - while the 2020LT hand held laser tool remotely triggers it from several metres.
