Before removing the cover for maintenance or calibration purposes, ensure the
surrounding atmosphere is free of flammable gases or vapours.
x
Maintenance and calibration operations must only be performed by qualified service
personnel.
x
Only genuine Crowcon replacement parts must be used; substitute components may
invalidate the certification and warranty of the system.

ESCRIPTION
Vortex FP Compact 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 Compact may contain (depending on
specification) up to 16 relays for control of external devices.
Vortex FP Compact 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 Compact may be delivered configured for 1-4, 1-8 or 1-12 input channels, and
with up to two 8-way relay modules (one relay module only if three input modules are fitted).
If intrinsically safe (I.S.) field devices are to be connected, the required Zener barriers or
galvanic isolators must be located within a separate Exd certified enclosure. Alternatively a
larger version of the product: Vortex FP is available with space sufficient for such devices.
Please refer to the specification sheet provided with the system for exact configuration
details.
Vortex FP Compact 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 Compact is not available with back-up batteries fitted. For continued operation in
the event of mains supply failure, it is recommended that Vortex FP Compact is connected to
a suitable UPS system.
