SENSEPOINT RFD OPERATING MANUAL

1 Safety

Ensure that this Operating Manual is read and understand BEFORE installing / operating /
maintaining the equipment. Pay particular attention to Warnings and Cautions. All document
Warnings are listed here and repeated where appropriate at the start of the relevant
chapter(s) of this Operating Manual. Cautions appear in the sections/sub-sections of the
document where they apply.
Sensepoint RFD is designed for installation and use in Zone 1 or 2 hazardous areas in Europe and
Class 1 Division 1 or 2 area applications in North America.
Installation must be in accordance with the recognized standards of the appropriate authority in the
Access to the interior of the detector, when carrying out any work, must only be conducted by
Before carrying out any work ensure local regulations and site procedures are followed. Appropriate
standards must be followed to maintain the overall certification of the detector.
For installations where conduit is used, and the sensor is mounted directly to the Sensepoint RFD,
there must be a "Seal Fitting" installed within 18 inches of the Sensepoint RFD. For installations
where the sensor will be mounted remote from Sensepoint RFD, two "Seal Fittings" will be
required: One at the conduit entrance for the power/signal and one at the sensor wiring entrance.
The total distance of the location of these Seal Fittings is 18 inches. (e.g. Seal Fitting located within
10 inches of the power/signal entrance and the second Seal Fitting within 8 inches of the sensor
If using an anti-seize compound, the threads should be thinly coated with an approved silicone
To reduce the risk of ignition of hazardous atmosphere, de-classify the area or disconnect the
equipment from the supply circuit before opening the detector enclosure. Keep assembly tightly
Never attempt to open a junction box/enclosure or replace/refit the sensor in potentially
The detector must be earthed/grounded for electrical safety and to limit the effects of radio frequency
interference. An earth/ground point is provided inside and outside the unit. Ensure that all
screens/armor are earthed/grounded at a single star point at the controller or detector - BUT NOT
BOTH - to prevent false alarms due to earth/ground loops.
Only replace the Remote Handheld Interface batteries in a non hazardous area. Only replace the
batteries with approved 'AAA' alkaline batteries, Energizer E92 or Duracell MN2400. Use only two
new batteries of the same type when replacing batteries. The Handheld Remote Interface has
Do not expose to temperatures outside the recommended range.
Do not expose sensor to organic solvents or flammable liquids.
At the end of their working life, sensors and batteries must be disposed of in an environmentally
safe manner. Disposal should be according to local waste management requirements
Alternatively, sensors may be securely packaged and returned to Honeywell Analytics clearly marked
