NFORMATION
Vortex FP is a certified Flameproof (Exd) detector suitable for use in ATEX Zone 1 or Zone 2
hazardous areas.
•Vortex FP must be installed, operated and maintained in strict accordance with these
instructions, warnings, label information, and within the limitations stated.
•The cover retaining bolts must be kept tightly closed until power to the control system
is isolated - otherwise ignition of a flammable atmosphere can occur.
•Before removing the cover for maintenance or calibration purposes, ensure the
surrounding atmosphere is free of flammable gases or vapours.
•Maintenance and calibration operations must only be performed by qualified service
personnel.
•Only genuine Crowcon replacement parts must be used; substitute components may
invalidate the certification and warranty of the system.
•Vortex FP must be protected from extreme vibration.
•Vortex FP must be protected from direct sunlight in hot environments as this may
cause the temperature of the system to rise above its specified limits and cause
premature failure.
•Vortex FP is supplied certified for use in hazardous areas only with the components
originally fitted. No other devices may be fitted within the Vortex FP enclosure.

ESCRIPTION
Vortex FP is a sophisticated control system designed for monitoring up to twelve gas
detectors. Three input channels may alternatively be used for monitoring conventional
smoke or heat detectors, or flame detectors. Vortex FP may contain (depending on
specification) up to 24 relays for control of external devices.
Vortex FP is supplied in an Exd Flameproof junction box constructed of LM25 aluminium and
finished with a tough polyester coating. Gas levels, alarms and faults can be viewed through
the window, and system functions can be accessed either via the push-buttons or by using
the supplied ‘Crowmag’ magnetic key.
Vortex FP may be delivered configured for 1-4, 1-8 or 1-12 input channels, and with up to
three 8-way relay modules. Vortex FP may also have up to four Zener barriers or galvanic
isolators fitted for connection of intrinsically safe (I.S.) field devices. Please refer to the
specification sheet provided with the system for exact configuration details.
Vortex FP is based on Crowcon’s Vortex control system, and the standard Vortex manual
(part number M07211) must be referred to in conjunction with these instructions.
Vortex FP is not available with back-up batteries fitted. For continued operation in the event
of mains supply failure, it is recommended that Vortex FP is connected to a suitable UPS
system.
